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

(standard part number 2660-0211 and spare part number 466263-001) uses 512 Mb DRAM

chips. The new cache DIMM (standard part number 2660-0281 and spare part number 587246-

001) uses 1 Gb DRAM chips. This does not change the physical memory capacity (1 GB) of the

cache DIMM. It is a change to the controller memory module type only, which affects controller

policy and cache memory.

This memory module change requires a minimum version of XCS controller software (XCS

09522000) to support it. Additionally, you cannot mix the two DIMM memory types (for example,

spare part numbers 466263-001 and 587246-001) in one controller. Each controller within the

enclosure can have different DIMM memory types as long as both controllers are running a min-

imum of XCS 09522000.

NOTE:

The cache DIMM with the modified memory module (standard part number 2660-0281 and spare

part number 587246-001) requires a minimum of XCS 09522000. You cannot run any earlier

version of XCS or the controller will be rendered inoperative. New shipments of EVA4400

controllers with this cache DIMM will have a label stating Min FW 09522000 affixed to them.

Fixes

The following issue has been fixed in XCS 09522000:

• Addressed an issue where certain error handling instances on the EVA4400 could lead to a

controller halt.

The following issues have been fixed in XCS 09520000 and are included in XCS 09522000:

• Addressed an issue which could occur in 8Gb infrastructures in which host port perturbations

could cause the controller operation to terminate due to a watchdog timeout.

• Addressed an issue which caused the online disk drive firmware upgrade to fail intermittently.

• Addressed an issue where incorrect or incomplete disk enclosure I/O module information was

reported.

• Addressed an issue where an incomplete metadata write operation led to repetitive controller re-

starts.

• Improved disk enclosure I/O module handling which previously led to instability.

• Addressed an instance of controller termination due to a "TSDK Assert" condition.

• The EVA6400/8400 now correctly reports RoHS compliance on the controller hardware.

• Addressed an issue in which leveling did not complete after a disk drive topology change.

• Fixed OCP issues where certain menu selections caused the OCP to go blank or entering the

worldwide ID displayed all zeros.

• Fixed an issue where deleting a presented unit while the unit was still receiving I/O caused a

CSM reset or Unit Stalled Too Long condition

• During a DR group failover in an HP Continuous Access EVA configuration, the force full copy

action was stalled after the intersite link was resumed.

• Fixed an issue where a CSM reset condition occurred while waiting for leveling to complete.

• Addressed an issue where incorrect or incomplete controller status was reported.

• Addressed an issue which caused controller operation to terminate due to an inconsistent volume

ID block.

• Addressed an issue in the controller software that led to incorrect capacity reporting.

• Addressed an issue which led to repeated reporting of failure for a disconnected host port.
