HP StorageWorks Enterprise Virtual Array release notes (XCS 09522000) (5697-0233, November 2009)

• Addressed an issue of incorrect severity reporting for disk enclosure inter-I/O module communic-
ation issues.
• Previously HP recommended that customers disable the Enable time sync feature in HP Command
View EVA to avoid an issue in controller software for server-based management configurations.
This feature can now be re-enabled as per published best practices.
The following issues were fixed in XCS 09501x00 and are included in XCS 09522000:
• Fixed an issue where an Emulex Fibre Channel adapter, mezzanine card, or combination card
in an HP-UX 11.23 IA64 or 11.31 IA64 server failed to discover LUNs presented from an EVA4400
or EVA6400/8400 running XCS 09500000, 09501000, or 09501100. The affected 4 Gb
Emulex PCI-e HBAs are AD299A, AD335A, AD221A, AD222A, and AD393A and all Emulex
mezzanine cards, including those in the BL870 and BL860 blade servers.
• Addressed a condition where a disk group was declared inoperative due to missing disk drives.
• Fixed an issue where an unrecovered read media error from a disk drive caused a Unit Stalled
Too Long error to occur or host I/O to stall on a LUN.
• Fixed an issue where a recursive termination could occur when a failed or missing disk drive was
being accessed during a rebuild parity operation and a subsequent controller resynchronization.
• Fixed an issue where a recursive termination could occur during snapshot creation.
• Fixed an issue where high snapshot write activity could lead to a controller reset.
• Fixed an issue where Fibre Channel switches using Extended Link Services (ELS) caused a controller
reset.
• Improved internal controller communication to reduce failure reporting.
• Improved I/O module firmware to reduce resets and loop disruption.
• Improved controller software to address controller replacement issues.
• Fixed an incorrect host port speed reporting issue.
• Improved controller role transition under a certain controller failure condition.
• Addressed an issue where a Linux host could see an unresponsive host port after a controller failure.
