HP 4400 Release Note page 7

Fixed an issue where the disk enclosure shutdown process would return a failure status even if
the shutdown operation succeeded.
Fixed an issue where some fields were missing or not completely populated in log events related
to disk enclosure link module status or firmware upgrades.
Fixed an issue where poorly seated back-end cables could result in too many dropped frame
(code 0x061d4709) and metadata error bit (e-bit) set (0x070e0015) events, flooding the logs.
Corrected an issue where the incorrect WWID entered from the operator control panel of an
EVA6400/8400 was accepted and stored with the secondary controller.
Fixed an issue where internal parity generation and checking resources were not configured
correctly.
Added event logging to output the current controller hardware revision and control and cache
memory configuration during boot.
Fixed event strings related to System Inoperative events.
Fixed an issue where the array logs a spontaneous power PC reset termination event instead of
the power loss event when power fails during a restart.
Fixed an issue where a controller host port could stop responding after a restart due to the improper
processing of brief, recovered link failures.
Fixed a controller restart that resulted from unexpected host mode sense requests.
Fixed a rare condition involving duplicate entries in a host port transaction buffer time and
organization queue. The problem appears to occur in all types of controllers and is not port
specific. A rare condition results, which may cause the item being aborted to be completed twice.
Fixed unnecessary failover/failback Unit Attention messages that are sent to hosts during controller
reboot. The messages affect hosts configured with host modes HP-UX, Sun Solaris, Windows
2003, and Windows 2008.
Fixed an issue where a controller can experience a watchdog timeout termination during host
port LUN processing.
Fixed an issue where 0x4207001b and 0x420d001b events were not being logged on EVA6400
and EVA8400 controllers.
Added event logging to increase visibility to host port Fibre Channel nameserver logins during
DR tunnel creation.
Fixed a Direct Memory Access (DMA) error that occurred when an active controller was physically
removed from an enclosure.
Improved the robustness and event logging associated with array initialization requests including
new events when initialization requests arrive, complete, or are malformed.
Fixed an issue where the array failed to boot when a disk containing quorum data from a different
array was inserted into the array.
Fixed an issue where a controller resynchronization would occur during a change of mastership.
Fixed a rare controller resynchronization that occurred when a controller mirror port disruption
occurred during a controller failover.
An issue was addressed that can arise when metadata instances from multiple storage systems
are discovered.
Fixed an issue on the EVA4400 that caused the SCID_FCS_LOOP_CONFIG (0x06410017)
event to not be generated when changes occurred during discovery of device enclosures and
disk drives.
