Operating Systems - HP 4400 Release Note

Fixed a problem that results in a controller termination during controller restart if a RSCN (Remote
State Change Notification) ELS (Extended Link Services) request is received prior to the start of
an HP P6000 Continuous Access discovery.
Fixed an issue where mirror cache is not synchronized when failover clears cache data lost on a
DR group, leading to a termination when proxy I/Os arrive.
Fixed an issue where the data replication protocol could inadvertently change to SCSI-FCP after
a controller software upgrade.
Fixed an issue where a controller on the DRM remote array can experience a Unit Stalled
Too Long or CSM Reset termination during a secondary to primary controller LUN transistion.
Fixed a problem where dynamic expansion of DR logs could create map inconsistency in metadata,
resulting in a recursive controller termination.
Operating system/solution support
This section describes issues affecting array support of operating systems or solutions.
Fixed an issue observed on Windows hosts configured with QLogic HPAK344A 8 Gb HBAs
where the queue depth counts were being cleared with I/Os active on a connection.
Fixed events and controller resynchronizations seen with some Brocade products.
Fixed a problem with abort task and LUN reset responses not being returned correctly to HP-UX
hosts.
Fixed slow link-up problem for an HP-UX host with an 8 Gb Fibre Channel adapter that is connected
to an EVA4400.
Fixed issues which prevented proper interaction with Windows 2008 KMS server activation.
Upgrades (controller software, I/O module firmware, disk drive firmware)
This section describes issues affecting upgrades involving controller software, I/O module firmware,
or disk drive firmware.
Fixed an issue where controllers do not shut down as intended following a situation where disk
enclosures overheat and bypass drives. This issue can result in improper array start up, thereby
leaving the array vulnerable to cache data loss conditions.
Fixed an issue where environments with multiple DR groups can experience more than 60 second
resynchronization times after a controller software upgrade.
Fixed a case where I/O modules did not report status correctly after an I/O module firmware
upgrade.
Fixed multiple issues involving communications between enclosure link modules within a disk
enclosure that could inhibit or block firmware upgrades to the enclosure.
Improved resynchronization times for online controller software upgrades.
