Last Update:   01/28/2008    ==========================================================================  Version History for the IBM DS4000 Fibre Channel Hard Disk Drive and   EXPxxx drive expansion enclosure ESM Firmware Update Pack  ==========================================================================        1. IBM DS4000 FC Hard Disk and EXP100/420/710/810 ESM Update Program           Version 1.57 - 01/26/2008         Updated the EXP710 ESM firmware to 9673.         Updated the EXP810/EXP420 ESM firmware to 98B3.         - Fix 386583, CR128599/CR131243/CR131110 ESM upgrade to 9661 on            EXP710s fails on DS4500.            Description:  While attempting to update the ESM fw from 9639 to            9661. One channel always went down and it only recovered after a            ESM with fw 9640 has been installed. An investigation revealed            that the ESM that is directly connected to a channel will pull the            channel down if it had ESM code 9661. After the EXP710 has been            upgraded to 9661, a drive channel went down, All ESMs that are            connected to the drive channel are seen as unknown. On channel            that did not go down, the Drive channels are seen as optimal. All            other drive channels are going down as soon as a ESM with fw 9661            is connected to it. The event was triggered by some DS4500            controllers (and likely other) were found to have a problem,            related to CR 95892. These controllers failed to connect to EXP710            at 96.43 or later, due to CRC errors caused during the EXP710 SOC            PTBI Lite diagnostic. This is apparently due to minor timing            differences in the Tachyons on the DS4500.             Where Seen:  When updating ESM Firmware (fw) from 9639 to 9661            when system is at 06.12.56.00.            Symptom: EXP710 ESMs connected directly to the controller will have            the link to controller stay down after a FW upgrade.   In the            96.43 SBOD code, the PTBI Lite to PTBI Regular toggling was            removed to resolve CRs 108149 and 94410.            Resolution: The issue was resolved by adding in enhanced PTBI            toggling, where PTBI Lite would be tried for 3 iterations before            switching to PTBI Regular.             Updated the HDS725050KLA360 drive firmware files to CTA. CTA fixes listed          below:         -SDB FIS A1 with an invalid SActive bit is sent to the host during NCQ Write           operations.  The following conditions can result in this:          *  Write Cache Disable          *  Mixed Non-NCQ / NCQ Write workload          *  Write DMA command followed by a sequential Write FPDMA command          *  FW includes performance improvement for NCQ Sequential Write with Write Cache Disable          After Write DMA command completes, used cache segment is left active, then a subsequent          sequential Write FPDMA command executes where a cache scan results in a Sequential Hit          to the Active cache segment.  This results in sequential Write FPDMA and Write DMA extending          write operations to the disk.  After all write data has been completed to disk, firmware          tries to send SDB FIS A1 for NCQ Write command from the non-NCQ write path.  This results          in a invalid SDB FIS being sent to the host. The fix is to Check previous command is NCQ          before allowing firmware to execute new NCQ command as sequential.                  Firmware Changes in LP1158:          New default setting for SERDES values in Polaris card image.  New           defaults settings value = RC_RX_EQ={10,1,0,10,1,0}.  New settings          were requested by manufacturing in order to speed up manufacturing          processes.  This firmware the same as LP1157 but with this default          setting value added.                Version 1.56 - 12/03/2007         Updated the EXP710 ESM firmware to 9663.         Version 1.55 - 10/31/2007         Replace to correct ST3500641NS driver firmware in SATA_HDD_SM9x_format         folder.  Firmware header string was changed from...         ST3500641NS         39M4517 39M0181 IBM         to...         ST3500641NS         39M4557 39M0181 IBM.         This corrected error message of "drive firmware is incompatible".           Repackaged and reposted to fix corrupted version of EXP810 ESM         firmware 98A3 and to fix corrupt hard disk firmware files contained         in the x_HDD_SM9x_format folders (10/24/2007).           Updated the ST373455FC, ST3146855FC, ST3300655FC drive firmware         files to B977.  This firmware has a fix for manufacturing only         firmware updates.           Firmware Changes in LP1157:           52269 ENG_411 Polaris build that has the TOV for the spin-up increased                to 300 seconds           51805 ENG_402 Final work around for LISM handling issue in a open loop                situation and DLM=0          51808 Possible lost inbound frames          51832 ABTS for an IO in the task list doesn't get BA_ACC          52085 ENG_407 PANIC TARGET 1 77 - Target FC IB parity error.          52089 ENG_409 Drive fault when sector 0 is not readable on startup          Updated the ST3500630NS and ST3750640NS drive firmware files to        3.AEP.          Updated the EXP100 ESM firmware to 9566.          Updated the EXP420 ESM firmware to 98A3.          128871/128502 (CL #WIC~128502) Boot Panics When Power Supply with a Bad I2C bus is installed          128873 (RW #WIC~127755) (CL #WIC~127754) (CAL05184) For SEOC Retry, increase retries and add debug dump          128874 (CL #WIC~127984) (TD_PT24173) ESM failed during continual upgrade/downgrade           123473 mfgSubsystemLineShow "AltESMRunning" command is failing          124377/124378 (CL #WIC~124071) (2-178252461) Bad Zone Recovery did not activate on li           125459 Husker panics or is reset by alternate during State Capture upload          117836 CLI command logClear during SES stress test results in a watchdog timer panic          119116 Move Log Buffer Init Before SPI Bus Init in System Initialization          121952 (CL #WIC~121564) SOC SERDES pwr reg at 2 gig changed          Updated the EXP710 ESM firmware to 9662.

This firmware has the fix to the drive reporting        an invalid frame as an 04/44/98 internal hardware error rather than        a 0b/44/98 retryable error.         Version 1.53 - 4/26/2007        Updated EXP710 ESM firmware to 9661 to         - Support the intermix of EXP810, EXP710 and EXP100 enclosures behind a           DS4300, DS4500, DS4700 and DS4800 storage subsystem with controller           firmware 6.23.xx.xx or later.        - Fix 94410 Critical error DRIVE_TRAYS_NOT_GROUPED_TOGETHER.           MEL Event type 2835 Drive trays not cabled correctly. Fixed by adding           the same SEOC retry mechanism as used in EXP420/EXP810 ESM firmware.          Updated EXP420/EXP810 ESM firmware to 9898 to support          - The intermixing of the Fibre Channel and SATA E-DDMs within the same           DS4700 storage subsystem or EXP810 drive expansion enclosure.        - The intermix of EXP810, EXP710 and EXP100 enclosures behind a DS4300,          DS4500, DS4700 and DS4800 storage subsystem with controller firmware           6.23.xx.xx or later.                Updated the ST336605FC and ST373405FC drive firmware files to version         B34C This firmware version has the fix to the drive handling of Fibre         Channel LIPs and LPEs primitives, which is required to prevent drives         from being incorrectly marked as failures when having EXP810s in the         DS4300 and the DS4500 drive loop(s.)           Updated the ST373455FC, ST3146855FC, and ST3300655FC drive firmware files        to version B976.  This firmware version has the fix to the drive green        LED is off when idle after a power cycle.  The LED blinks with activity        and the drive is still optimal.                 Version 1.52 - 1/17/2007        Updated EXP420/EXP810 ESM firmware to 9884 for the following fixes.                   - 111133 Fixed improper fibre channel loop initialization                  (LIP) injection for disk drive devices. ESM firmware was                  obtaining the wrong arbitrated loop physical address                  (ALPA) resulting in a mismatched drive configuration.        - 114285 Fixed ESM failures due to flash timeout. EXP810                  indicates ".8".        - 114295 Fixed ESM with wrong tray ID when swapped.        - 114298 Fixed multiple drive failures when processor has failed                 (".8).           Version 1.51 - 10/30/2006        Include the following required updates to support the intermix         between the EXP810 and EXP100 storage expansion enclosures and the        attachment of EXP810s to the DS4300 and DS4500 subsystems.           -  Updated the EXP810 ESM firmware to 9881         -  Updated the EXP710 ESM firmware to 9640         -  Update the drive firmware of the following Fibre Channel drives to            the levels as stated in the table below. The fix to the drive            handling of Fibre Channel LIPs and LPEs primitives, which is            required to prevent drives from being incorrectly marked as failures            when having EXP810s in the DS4300 and the DS4500 drive loop(s.)                         ---------------------------------------------            | FC  Drive Product ID   |  Firmware Version  |             ---------------------------------------------            | ST3146807FC            |      B35F          |            | ST373307FC             |      B35F          |            | ST336607FC             |      B35F          |            | ST318307FC             |      B35F          |             ---------------------------------------------            | ST318453FC             |      B95E          |            | ST336753FC             |      B95E          |            | ST373453FC             |      B95E          |             ---------------------------------------------            | ST3146854FC            |      B96C          |            | ST373454FC             |      B96C          |            | ST336754FC             |      B96C          |             ---------------------------------------------             | ST3146954FC            |      B90A          |            | ST373554FC             |      B90A          |            | ST336854FC             |      B90A          |             ---------------------------------------------                 Version 1.50 - 5/24/2006        Updated the EXP700 ESM firmware to 9330 to incorporate the following        fix.         - 999718/99956 - several 0x280D and/or 0x280C errors incorrectly           posted in the subsystem event (MEL) log after the DS4000 controller           firmware is updated to 6.12.16.00 or later. These errors mislead           the customers into thinking that they are having hardware failures           when there is none.                    Updated the EXP710 ESM firmware to 9639 to incorporate the following        fixes/updates.           - Fix the i2c bus timeout that caused ESM incorrectly reporting           hardware failures (90949/90152).        - Fix the i2c bus read problem in the ESM modules that resulted in           several 0x280D and/or 0x280C errors incorrectly posted in the           subsystem event (MEL) log after the DS4000 controller firmware is           updated to 6.12.16.00 or later. These errors mislead the customers           into thinking that they are having hardware failures when there is           none (99861/99718).        - Fix the "drive tray not connected correctly" in DS4800 storage          subsystem with EXP810s and EXP710s intermixing in the same drive           channels (100949/99810)         - Improve ESM handling of internal EXP710 i2c bus errors           (98007/cal05913).        - Shorten the ESM reboot time to 15 seconds to allow faster recovery           during DS4000 storage subsystem startup or after ESM firmware           download (102261.)                    Updated the EXP810 ESM firmware to 9865 to support the new 4Gbps         fibre channel drive modules and to fix the memory leak in the EXP810         ESM SES API code, which could result in a depletion of ESM memory         resources. (101242)                Updated drive firmware for the fibre channel drives with the         following Product ID strings HUS103073FLF21, HUS103030FLF21 and         HUS103014FLF21 to JFQ8 to fix a potential incompatibility problem         with the new DS4000 4Gbps hard drive options when hot inserting the         new DS4000 4Gbps drives in the same DS4000 EXP drive expansion         enclosure that these drives are located. The 4Gbps drives will be         operated at 2Gbps mode in this condition. It also incorporate         maintenances fixes for the several low-severity problems.                General released drive firmware version B909 for the 4Gbps fibre         channel drives with the following Product ID strings - ST336854FC,         ST373554FC and ST3146954FC.                  Version 1.49 - 2/17/2006        Updated drive firmware for the fibre channel drives with the         following Product ID strings - ST336754FC, ST373454FC and ST3146854FC         - to version B96B to correct the reporting of IBM hard drive part         number.           2. IBM DS4000 FC Hard Disk and EXP500/700/710 ESM Update Program       Version 1.48 - 11/22/2005        Updated drive firmware for the fibre channel drives with the         following Product ID strings - ST336754FC, ST373454FC and         ST3146854FC - to version B969 to turn SMART PERF bit on to improve         drive latency.                       Version 1.47 - 10/24/2005        Updated the EXP700 ESM firmware to 9329 to incorporate the following        fix.           - 93692/90152/88897 (C294615) - several 0x280D and/or 0x280C errors          incorrectly posted in the subsystem event (MEL) log after the           EXP700 ESM is upgraded to 9328.            Version 1.46 - 07/26/2005        Updated the EXP700 ESM firmware to 9328 to incorporate maintenance        fixes.           - 90152 - ESM firmware has a too short i2c timeout value causing          unnecessary device failures reported        - 280D errors after upgrading EXP700 ESMs to ESM firmware version           9327 (C280030)                    Version 1.45        Updated the EXP710 ESM Firmware to 9631 to incorporate maintenance         fixes.                   - Fix the notification problem between the Switch-JBOD chips (SOC)           in the EXP710 ESM during the DS4000 storage subsystem powering           up that might caused the EXP710 ESMs to falsely believe they were           not connected to other EXP710 ESMs. This in turn lead the DS4000           controllers to think that the EXP710 drive enclosures were not           properly clustered together (83970).                - Fix the problem that might cause drive(s) to report a loss of           redundancy after hot swapping the EXP710 ESMs as part of a ESM           replacement procedure. The problem was caused by the SerDes PLLs           on the SOC chips in the EXP710 ESMs locking onto the wrong           frequency at SOC power-up, causing loss of access to drive(s). As           part of this change to allow the EXP710 ESM time to boot up and           stabilize after being hot-plugged, the EXP710 ESM firmware will           now wait 12 seconds before unbypassing the external SFP           connections. One visible external indicator of this change is           that the EXP710 ESM SFP ports will flash for 12 seconds while           they are held in bypass, until they are released to "automatic"           /normal mode. (85965/TD_PT5331)            Updated drive firmware for the fibre channel drives with the         "Product ID" strings ST318453FC, ST336753FC and ST373453FC to B95B         and ST373307FC, ST336607FC and ST3146807FC to B35C to incorporate         enhancements and maintenance fixes. The list of enhancements are as         followed:                          1. Corrected & Updated List of Sense Key Error Codes that need              trigger to save to disc of Log Page 3Ah to improve the amount              of data collected during failures.          2. Fix drive false errors reporting while running background             write/read test           3. Incorporate Drive State Dump feature which is controlled through             mode page setting and can be initiated by SCSI command.          4. Change format of Inquiry page C4h to comply with IBM              Manufacturing test enhancements          5. Add Enable ECHO_FAULT_LED_TO_ACTIVE feature so that the HDD              drive fault blink codes are reported on HDD Activity LED              instead of Fault LED. This will allow customers and field              service to read the blink codes of faulty drives to assist with              drive failure analysis.                    This new version of drive firmware also contains various         maintenance fixes for field problems. Only the major severity         problem fixes are listed below:                    1. No Response to PLOGI          2. Drive goes bypass with no/rapid flashing of activity LED          3. Assert when busying port during CRC triggered abort          4. Target busy for >20 seconds after receiving LIP FF with WCE=0          5. Prediction not disabled following ABTS          6. No sense data after a check status          7. Need extra free retries for ROA issue causing 09/8000/C3           8. Format Immediate causes other commands to hang.          9. Port Busy Assert After Write merge Abort          10. Fix cleaning up of ALU Buffer Parity error prior to flashing              LED 0x19          11. Assert Failure: Dirty Segment Flags was set upon releasing               segment . This problem has been reported by some DS4000               customers          12. RLA algorithm overflow caused read command with long transfer               to timeout.          13. Corrupted DRAM read cause link service command timeout          14. Drive Hanging due to not reselecting for a read command or               hanging not sending the data for a read command          15. Assert with disk transfer ctb=null  when a paused WCE restarts.          16. Targeted LIP Reset during data-in phase causes target to OPN               itself.....WCE must be enabled.          17. Performance degradation on Write / Read until Reset is received.          18. Set "Perf" bit in mode page 1C to disable the Fly-Height               measurement subset of SMART data collecting. In certain IO               work load scenarios, this measurement might cause read               latency spikes whenever it is invoked as part of the drive               on-going SMART data collecting function.            Updated drive firmware for the fibre channel drives with the         following Product ID strings HUS103073FLF21, HUS103030FLF21 and         HUS103014FLF21 to JFQ4 to incorporate maintenances fixes for the         several low-severity problems. The most severe problem fixes are         listed below:         - drive hung after the OPN retry time-out occurred and the next queued           command the was fetched (dequeued) from the command queue is the          write command.                  - 60s timeout occurred for the random read/ write command when           large number sequential reads are received and get full cache hits          in different segments.        - problem that could degrade the write sustain rate and 1Gbps          write sequential performance.        - drive went into degraded mode and reported 04/4400 forever          after being reboot three times to recover from the drive S-RAM          correction.                  Version 1.44 - 03/15/2005        Updated the EXP710 ESM Firmware to 9629 to incorporate maintenance        fixes.                   - 81272 Drive-side timeouts with EXP710 on the DS4300 mreg (2)         - 82461 (C259426) : drives do not spin up when incorrectly                  connecting EXP710/EXP700 in non-clustered setup  (2)         - 83528 (WIC~80458) two drive enclosure IDs of 0 on the loop                 after doing simulated ESM pulls  (2)         - 79542 Drive side timeouts during benchmarks when using EXP710                enclosures                Updated the EXP700 ESM firmware to 9327 to incorporate maintenance        fixes.                    - 82950 LIP not generated as drives join the loop...ESM does                 not complete diagnostics              - 83188 2G ESM becomes unresponsive on fibre loop when peer                 has I2C failure                       - 83211 2G ESM sets SES bypass bits incorrectly when drive                 bypasses itself                         - 83812 Power cycle EXP700 trays caused loop stability issue due                to improper LISM             Version 1.43        Document the correct behavior when one inserts an ESM that does         not have same ESM firmware version as the surviving ESM in the         drive expansion enclosure in section 1.4 of the README file.         Modify section 1.5 of the README file to show the new IBM        recommended firmware upgrade sequence for the ESMs, controllers         and hard drives in an DS4000 storage subsystem configuration.                 Version 1.42 - 10/21/2004        Repackage the Drive firmware files so that they are recognized         as the drive firmware files by the DS4000 storage subsystem with         controller firmware version 06.xx.xx.xx installed.                Version 1.41        Updated EXP700 ESM Firmware to 9326 to correct memory corruption         issue that caused the ESM port name to change on the loop, resulting         in I/O errors. The memory corruption was occurring when the ESM sent         a response frame that didn't get taken off the loop for any reason         and came back to it, which might happen if one of the ports on the         ESM or controller tray were bypassed at the right time. This was         fixed with new Vitesse libraries. The new Vitesse libraries also         fixed a problem where the Vitesse code was occasionally incorrectly         removing some spawned tasks and preventing them from firing, which         was causing problems with loop diagnostics. There were some         additional changes to help make sure we report loop diagnostic         failures correctly by adding retries to the code for turning on         fault LEDs in case of temporary I2C failures. The new Vitesse         libraries also fixed some issues we were seeing with unexpected LIPs         on the loop under heavy I/O loads.          3. IBM DS4000 Hard Disk and EXP500 ESM Update Program       Version 1.40        Updated EXP700 ESM Firmware to 9324 to correct false fan and        temperature errors, correct problems where the drives in bays 11-14        would not spin up at power up, correct other drive side issues,         and provide support for copper GBIC cabling for use only with the         SAN Integrated subsystem.          Updated EXP500 ESM Firmware to prevent accidental corruption from         downloading the wrong firmware to the ESM.  In environments where         there are EXP500s and EXP700s in the same controller, it is         IMPERATIVE that all EXP500s ESMs are updated to 9166 before the         EXP700 ESM firmware is applied.                Updated firmware for drives with Strings ST318304FC, ST336704FC,         and ST173404FC to B338; ST318452FC and ST336752FC to B94a;         ST318432FC and ST336732FC to B949; ST318453FC, ST336753FC and         ST373453FC to B954; ST373307FC, ST336607FC and ST3146807FC to         B356 to correct a problem that caused the drive to marked offline         when a lip was received on both ports, corrected a problem where         the light for the drive would be lit green even if it failed an         internal diagnostic, corrected a problem where drives did not         report the proper status when a correctable error was         encountered, and corrected a performance problem when the drive         did queued sequential writes.      4. IBM DS4000 Fibre Hard Disk and EXP500 ESM Update Program       Version 1.30        Updated firmware for drives with ID strings of ST39103FC,         ST318203FC, ST136403FC to B325; ST336605FC, ST373405FC to B346;         ST318451FC, ST318452FC, ST336752FC to B946; ST318432FC,         ST336732FC to B947 to correct a performance issue where the         drives would recover slowly from Fibre Channel LIPs as well as         mode page enhancements for better log reporting of drive         activity. EXP500 ESM code is updated to 9166 to improve bypass         diagnostics when a bad GBIC is detected, correct an error where a         HDD replacement is logged when an ESM is replaced, correct a         condition where the ESM reports incorrect EXP component         information, and protects the ESM from accepting incorrect         firmware.      5. IBM Fibre Hard Disk and EXP500 ESM Update Program       Version 1.20        Updated firmware for drives with product ID strings of        ST318304F, ST336704F and ST173404F to B337, ST318451F        to B933 as well as disable write cache on all drives to        prevent drives from being failed by controller under extreme        circumstances      6. IBM Fibre Hard Disk Drive and EXP500 ESM Update Program       Version 1.10          Added update of EXP500 ESM Firmware from 9150 to 9163 to          prevent false fan alerts and correct diagnostic lights      7. IBM Fibre Hard Disk Drive Update Program       Version 1.01          Updated firmware for drives with product ID strings of          DDYS and DPSS to S9HA       8 IBM Fibre Hard Disk Drive Update Program       Version 1.00          Initial Release              __________________________________________________________________________  ==========================================================================  Version History for ESM firmware  ==========================================================================          1. For EXP810 drive expansion enclosure             A. ESM firmware 9898 to support           - The intermixing of the Fibre Channel and SATA E-DDMs within the same           DS4700 storage subsystem or EXP810 drive expansion enclosure.        - The intermix of EXP810/EXP710 and EXP100 enclosures DS4300, DS4500,           DS4700 and DS4800 storage subsystem with controller firmware           6.23.xx.xx or later.           B. ESM firmware 9884 to support the following field fixes        - 111133 Fixed improper fibre channel loop initialization                  (LIP) injection for disk drive devices. ESM firmware was                  obtaining the wrong arbitrated loop physical address                  (ALPA) resulting in a mismatched drive configuration.        - 114285 Fixed ESM failures due to flash timeout. EXP810                  indicates ".8".        - 114295 Fixed ESM with wrong tray ID when swapped.        - 114298 Fixed multiple drive failures when processor has failed                 (".8).           C. ESM firmware 9881 to support the intermix of EXP710 and EXP810 with           EXP100 storage expansion enclosures or the attachment of EXP810s in           DS4300 and DS4500 subsystems with controller firmware version           6.19.xx.xx or later.         D. ESM firmware 9865 to support the new 4Gbps fibre channel drive          modules and to fix the memory leak in the EXP810 ESM SES API code           (101242).                E. ESM firmware 983A is the initial firmware               2. For EXP710 drive expansion enclosure           A. Version 9661 to support           - Support the intermix of EXP810/EXP710 and EXP100 enclosures behind             a DS4300, DS4500, DS4700 and DS4800 storage subsystem with             controller firmware 6.23.xx.xx or later.           - Fix 94410 Critical error DRIVE_TRAYS_NOT_GROUPED_TOGETHER.             MEL Event type 2835 Drive trays not cabled correctly. Fixed by             adding the same SEOC retry mechanism as used in EXP420/EXP810 ESM             firmware.                B. Versionn 9640 to support the intermix of EXP710 and EXP810 with           EXP100 storage expansion enclosures or the attachment of EXP810s in           DS4300 and DS4500 storage subsystems with controller firmware version           6.19.xx.xx or later.           C. Fixes in ESM firmware 9639          - Fix the i2c bus timeout that caused ESM incorrectly reporting             hardware failures (90949/90152).          - Fix the i2c bus read problem in the ESM modules that resulted in             several 0x280D and/or 0x280C errors incorrectly posted in the             subsystem event (MEL) log after the DS4000 controller firmware is             updated to 6.12.16.00 or later. These errors mislead the customers             into thinking that they are having hardware failures when there is             none (99861/99718).          - Fix the "drive tray not connected correctly" in DS4800 storage            subsystem with EXP810s and EXP710s intermixing in the same drive             channels (100949/99810)           - Improve ESM handling of internal EXP710 i2c bus errors             (98007/cal05913).          - Shorten the ESM reboot time to 15 seconds to allow faster recovery             during DS4000 storage subsystem startup or after ESM firmware             download (102261.)         D. Fixes in ESM firmware 9631          - Fix the notification problem between the Switch-JBOD chips (SOC)             in the EXP710 ESM during the DS4000 storage subsystem powering up             that might caused the EXP710 ESMs to falsely believe they were             not connected to other EXP710 ESMs. This in turn lead the DS4000             controllers to think that the EXP710 drive enclosures were not             properly clustered together (83970).                    - Fix the problem that might cause drive(s) to report a loss of             redundancy after hot swapping the EXP710 ESMs as part of a ESM             replacement procedure. The problem was caused by the SerDes PLLs             on the SOC chips in the EXP710 ESMs locking onto the wrong             frequency at SOC power-up, causing loss of access to drive(s). As             part of this change to allow the EXP710 ESM time to boot up and             stabilize after being hot-plugged, the EXP710 ESM firmware will             now wait 12 seconds before unbypassing the external SFP             connections. One visible external indicator of this change is             that the EXP710 ESM SFP ports will flash for 12 seconds while             they are held in bypass, until they are released to "automatic"             /normal mode. (85965/TD_PT5331)                  E. Fixes in ESM firmware 9629          - 81272 Drive-side timeouts with EXP710 on the DS4300 mreg (2)           - 82461 (C259426) : drives do not spin up when incorrectly                    connecting EXP710/EXP700 in non-clustered setup  (2)           - 83528 (WIC~80458) two drive enclosure IDs of 0 on the loop                   after doing simulated ESM pulls  (2)           - 79542 Drive side timeouts during benchmarks when using EXP710                  enclosures         F. ESM firmware 9627 is the initial firmware        3. For EXP700 drive expansion enclosure            A. Fixes in ESM firmware 9330               - 999718/99956 - several 0x280D and/or 0x280C errors incorrectly              posted in the subsystem event (MEL) log after the DS4000              controller firmware is updated to 6.12.16.00 or later. These              errors mislead the customers into thinking that they are having              hardware failures when there is none.          B. Fixes in ESM firmware 9329              - 93692/90152/88897 (C294615) several 280D and/or 280C errors             incorrectly posted in the subsystem event logs after the EXP700             ESM is upgraded to 9328.                       C. Fixes in ESM firmware 9328              - 90152 - ESM firmware has a too short i2c timeout value causing            unnecessary device failures reported          - 280D errors after upgrading EXP700 ESMs to ESM firmware version             9327 (CMVC 280030)                  D. Fixes in ESM firmware 9327          - 82950 LIP not generated as drives join the loop...ESM does not            complete diagnostics                - 83188 2G ESM becomes unresponsive on fibre loop when peer has             I2C failure                         - 83211 2G ESM sets SES bypass bits incorrectly when drive              bypasses itself                           - 83812 Power cycle EXP700 trays caused loop stability issue             due to improper LISM                E.
