Deliverable Name:
HP Smart Array Controller Firmware Release for HP SA P400, P800, E500 and P700m controllers supported on Integrity Servers.    

Release Version and/or Date:
      fw ver: 7.22 EFI ver: 3.20

Last Recommended or Critical Version:
      fw ver: 7.22 EFI ver: 3.20

Previous Version of Firmware:
      fw ver: 7.18 EFI ver: 3.06

Firmware Dependency:

• Updating the HP MSA 60 and/or MSA 70 firmware version to 2.16 or higher is required to enable dual domain functionality.

Enhancements/New Features:

• Enhanced the SATA NCQ (Native Command Queuing) drive rebuild algorithm to continue progression in the event that individual block(s) cannot successfully be regenerated due to read error(s) such as UREs (Unrecoverable Read Errors) on the source drives.  Any individual blocks that cannot be regenerated during the drive rebuild will be marked as inaccessible on the rebuilding drive including those above the 137GB address.
  

Problems Fixed:

• Added fix for a POST message indicating potential data loss due to the expiration of the battery-backed cache batteries on the HP Smart Array controller, following an abrupt primary power loss in an HP server.
• Fixed an issue that resulted in unnecessarily disabling the write cache after the battery-backed cache batteries expire following an abrupt primary power loss.
• Fix for an incomplete or problematic data transfer issue on RAID 0 or RAID 1 volumes, which may occur under heavy I/O workloads. This issue may happen when array accelerator cache-bypassed write operations take place on a common small Logical Block Addressing (LBA) region on the drive, following multiple discontinuous non-overlapping cached writes.
