Last Update: 02/17/2006 ========================================================================== 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 EXP500/700/710/810 ESM Update Program Version 1.49 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 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 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 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 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 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.
