Linux Update Package Instructions: To install, enter the following on the command line: rpm -Uvh linflash-3.03-0.i386.rpm You must copy the firmware image to the same directory for the linux flash utility to work. Create a diskette image of the firmware and copy the .rom file to the same directory as linflash. Usage : linflash [-r] [-p] [-s] [-i [file] [file] [...]] [-f [file] [file] [...]] -r : Flash without asking for user input to flash adapter(s). -p : Prompt user for filename. Flash without checking for signatures. -s : Silent flash. First matching image file will be taken for each adapter. -i : Ignore the following files. These files will not be considered for flashing the matching controllers. -f : Force the following files To be flashed for the matching controller. In case more than one matching files are specified, the first one would be taken. To uninstall the rpm, enter the following command: rpm -e linflash 3.0 Fixes or Enhancements Component Current Version Previous Version Firmware 250O 2.48 BIOS 1.06 1.06 Ctrl-M U821 U812 Boot Block 1.7.4Dell 1.7.1Dell Bug Fixes: 1. Addressed issues found with the Firmware status Queue. This was causing the firmware to post status completion of command IDs still in progress, causing the driver to reuse those command IDs. 2. Addressed an issue in the media error counter logic when drives with media errors are replaced. 3. Improved rebuild logic to handle multiple media error in the same array in corner case conditions. 4. Improved Firmware error handling and messages for TBBU related events. Enhancements: 1. Improve firmware behavior and reporting when a multi-bit error is encounter at boot time. If an unrecoverable (multi-bit) error is encountered, during a cache scrub at initialization, the cache is re-initialized. 2. Improve the Firmware interrupt handling for all possible interrupts and takes specific actions based on the type and source of the interrupt. 3. Improve firmware failure algorithm for failed drives based on SAF-TE information. 4. Improved firmware error handling for cable pulled/removed situations. 5. Improved firmware algorithm and error handling for drive roaming scenarios and deleted Logical Disks. 6. Improved error logging and debug information collection when the firmware hangs or crashes. 7. Improved BIOS status reporting and messaging during POST. 8. Improved error firmware handling when drives return Hardware Error (sense key code 04) in some configurations. 4.0 Important Information Firmware upgrade while controller is doing background I/O task Firmware upgrade process will fail if any background I/O task (i.e. RAID-5 background consistency check or power on auto-resume rebuild and reconstruction) is being performed. The program will stop at the "Flash Download" screen with the following message: "Consistency Check of logical drive(s) in progress for adapter-X. Failed Writing Image on Adapter X with Baseport ...". Firmware and configuration on the adapter will not be modified by the program. A reboot can be performed to return to the Operating System. Wait until the background task completes before updating the firmware. Universal CRTL-M: Multiple adapters can be configured from CRTL-M, but currently selected adapter should be verified before performing any configuration changes using the Select Adapter option. Drive Migration: When hard drives are moved from one controller to another, the target controller configuration must be cleared to ensure a configuration mismatch does not occur. FlexRAID: FlexRAID Virtual Sizing is no longer supported by the current firmware (v.2.48) and should be disabled prior to firmware flash. This can be performed from CRTL-M by accessing Objects -> Logical drive -> View/Update Parameters -> FlexRAID Virtual Sizing and will need to be performed for each logical drive present. 5.0 Change History Change History from 2.37 to 2.48 Firmware Enhancements 1. Improved hard drive status logic when virtual disks are spanned across channels. 2. Firmware will automatically change cache settings to WriteThru when a battery problem is detected to preserve data. If WriteBack was originally selected, firmware will switch back once battery problem has been corrected. 3. In the Rebuild function of CRTL-M, a new status called “INCON” will be displayed after a rebuild operation completes if any unrecoverable errors are found in any of the hard disk drives. To identify the location of the error and if any data was present, run a check disk from the O/S (e.g. chkdsk in windows). Note: Dell recommends that a check disk or consistency check should be run after any RAID rebuild operation is completed by the controller. Firmware Bug Fixes 1. When multiple hard drive media errors are encountered, array rebuild operation will complete. 2. Consistency checks are aborted after reboot in cluster or stand alone mode. User must restart consistency check manually if needed. 3. Manual initialization calls will be rejected if a background initialization or consistency check is in progress on the logical drive. 4. Address potential controller lock-ups that could occur during either degraded, rebuilding or multiple drive pull and reinsert scenarios. 5. Addressed potential controller freezing during driver failure on possible Raid configurations. Change History from 2.27 to 2.37 Firmware Enhancements None Firmware Bug Fixes 1) Fixed Blue screen due to a misbehaving drives. 2) Changed the request sense length to 0x10 from 0x12. This was owing to CRC errors on Seagate drives. 3) Fixed issue where misbehaving drive would cause the system to hang. 4) Fixed NVRAM issue related to downgrading firmware. 5) Fixed issue where BGI would run during an NVRAM mismatch. 6) Sense Info pointer now increments correctly. 7) Fixed issue where rebuild might not restart after reboot. 8) Added fix for the firmware to keep checking for hot spare if the first rebuild fails. 9) Fixed a problem where the firmware would continuously respond to an auto request sense failure from a failing hard drive. 10) Fixed a conflict with Direct I/O, No Read-Ahead, and Write-Through cache parameters and platforms with more than 4 GB of system memory. BIOS Changes None Ctrl-M Changes None WebBIOS changes None Change History from 2.24 to 2.27 Component Current version Previous version Firmware 2.27 2.24 BIOS 1.04 1.03 Ctrl-M 5.62 5.62 WebBios 1.65 1.65 Firmware Enhancements None Firmware Bug Fixes 1. There was a data corruption for I/Os in Write Back mode, introduced during implementation of fast I/O feature in WRITE BACK mode in an earlier version. We then disabled it as per request in release version 2.21. We thought that was only for that specific release. Since it was enabled in the common code the bug reappeared in the later version. 2. Battery status was not properly detected. WebBios Bug Fixes None WebBios Enhancements None
