Fixes and Enhancements for Firmware Release Build 33263
This release provides the following fixes and enhancements:
•
•
•
•
•
•
•
•
•
•
•

2.1.1.2

Added support for the LED to light on the target device during COPYBACK task.
Fixed an issue where the device was not detected after a hot-add.
Fixed an issue where a drive command timeout could cause the adapter to reset.
Fixed an issue where a redundant logical drive could fail after single drive failure.
Fixed an issue where the UEFI drive would be incorrectly identified.
Fixed an issue where the logical drive size was inconsistent between BIOS and PBSI.
Fixed an issue to properly display the Micron 5100 SSD firmware version in PBSI.
Fixed an issue with a slow shutdown when logical drive was failed or degraded.
Fixed an issue where the firmware would crash after a rebuild with maxCache enabled.
Fixed an issue where the OS adapter would reset during multiple-controller Kdump activity.
Fixed an issue where the logical drive would fail when a metadata write failed during rebuild.
Fixed an issue to honor PBSI frequency settings.

Fixes and Enhancements for Firmware Release Build 33204
This release provides the following fixes and enhancements:• Removed support for auto-detecting the hot-plugged drives feature from ExtScsiPassThru layer
without needing to reload the controller UEFI driver.
• Previous behavior: Drives that are added after the UEFI driver has loaded could be seen by the
UEFI driver by making a second call to the function EfiScsiPassThruGetNextTargetLun. Thisbehavior has now been removed.
• Current behavior: To see hot-plugged drives added after the UEFI driver has loaded, you willneed to remove and reload the controller UEFI driver and then you will see the new drives.
You will no longer see hot-plugged drives by calling the EfiScsiPassThruGetNextTargetLun
function.
• Risk: Low• Added support for physical drive failure events through PBSI event logging.
• Added support for Green Backup events through PBSI event logging.
• Added support to allow RAW drives to remain in a spun-down state when the user spins down thedrive.
• Exposure: Applies to RAW drives only.
• Fixed an issue where the console showed a controller cache warning due to a backup unit fault
after flashing new firmware in UEFI mode.
• Fixed an issue where the box display order could be inconsistent during POST.
• Fixed an issue with setting the Spare Drive Flag=0 for PBSI event logging.
• Removed bad character from "Physical drive failure" field in PBSI.
• Fixed a timestamp issue in PBSI.
• Fixed an issue where RAW drives were lost when spun down and followed by an ARCCONF RESCAN.

Microsemi Proprietary and Confidential. Release Notes Revision 2

9What is New?

• Fixed an issue with a media change error message in the UEFI script, causing a script failure.
• Fixed an issue where entering the system BIOS, changing and saving a setting, then exiting caused
the system to hang (introduce CPLD 12).
Note:
CPLD is not activated automatically with a standard firmware flash. To update CPLD, run thefollowing command in ARCCONF: ARCCONF CPLD 1 FLASHUPDATE
See the Microsemi Adaptec RAID Controller Command Line Utility User's Guide (ESC-2160659)
for more information.
• Fixed an issue where the drive would go offline during an expander reset operation.
• Fixed expander mapping issues.
• Fixed an issue where the Read Buffer would fail.
• Fixed an issue where the controller would hang when the drive member was removed from a RAID
5 array.
• Fixed an issue where the UEFI would freeze while saving the support archive.
• Added support for driver NMI feature to controllers.
• Fixed an issue where the INQUIRY to VPD page 0xB0 WRITE SAME length was leading to IO timeouts.
• Root cause: The INQUIRY to VPD page 0xB0 has a field to specify the maximum WRITE SAME
length that the drive can support. SAT-4 had this field as unspecified and therefore SATL wassetting it. However, this is the field that the latest Linux version uses to determine the proper
WRITE SAME size to send and treats "0" as the sending maximum. This led to IO timeouts.
• Exposure: Setting correct fields in INQUIRY to VPD page 0xB0.
• Fix: Set the WRITE SAME length field to the maximum amount a 512-buffer can accept.
• Risk: None
• Set the SES, STE, SVPD to a higher priority.
• Root cause: The firmware sends an RCV_DIAGNOSTICS command to the VSEP every 10 seconds
and will time out this command if it does not receive a completion within 30 seconds. In highly
loaded systems, the SVPD thread may not wake up within 30 seconds, causing the firmware
to time out the command.
• Exposure: ARC programs• Fix: Increase the priority of the SES, STE, and SVPD threads. These threads are low-activity
threads and should be serviced immediately by the firmware. The high-activity threads, like
SAS_FAST, will have a lower priority relative to the SES, STE, and SVPD threads.
• Risk: Low

2.1.2

Driver Fixes

2.1.2.1

10What is New?

• Fix: This was an upstream patch, which was propagated into the out-of-box driver.
• Risk: Low• Backported inbox changes from 50740 to an out-of-box driver.
• Root cause: In order to harmonize in-box/out-of-box drivers, sync changes between the two
drivers.
• Fix:• Risk: Low• Fixed an issue with the static code analysis.
• Root cause: Correct static code analysis issues.
• Fix:• Risk: Low• Fixed an issue where some devices may be offline after a reset.
• Root cause: Devices which caused errors may be offline after reset.
• Fix: Reset offline devices to be available after reset.
• Risk: Low• Reworked the IOP_Reset functionality.
• Root cause: In-box driver 50834 included changes to the IOP_Reset functionality.
• Fix: Backported these changes to the inbox driver.
• Risk: Low• Fixed an issue where the ARCCONF reset command could hang.
• Root cause: Need to ensure that we are the only user of ioctl commands.
• Fix: Protect access using the ioctl mutex.
• Risk: Low• Added support for kdump on 3 or more adapters.
• Root cause: When using reset devices, an IOP Reset for each controller will take 45 seconds,
while the timeout for bringing devices online is 120 seconds. A method was required to performa soft reset that will not take as long as an IOP Reset.
• Fix: Incorporated the soft-reset functionality, and dropped IO in firmware to allow the kdump
to be able to handle more than two controllers.
• Risk: Medium• Fixed an issue where the ARCCONF does not respond to commands after lockup on second controller.
• Root cause: Check for controller failure during ioctl processing.
• Fix: Included a check for controller health prior to executing ioctl.
• Risk: Low• Fixed an issue where a controller would unexpectedly reset due to a lack of resources.
• Root cause: Some fibs would not be returned to the management free pool.
• Fix: Included a check to determine which pool a fib belongs to and return appropriately.
• Risk: Low• Fixed an issue where kdump would not function on RHEL 7.1.
• Root cause: Kdump on RHEL 7.1 would only allow 30 seconds prior to issuing a SIGKILL, whichcaused the driver to report an error.
• Fix: Included a workaround for RHEL 7.1, which would not be interruptible during kdump.
• Risk: Low
