HP Continuous Access EVA This section describes issues affecting HP Continuous Access EVA implementations of remote replication, including data replication (DR) groups. • Resolved a recursive controller termination that could occur if, during a DR failover from one array to another, the failover array has only one active controller, resulting in cached information that is not copied to the restarted partner controller. When the restarted controller became the master controller prior to the cached work being flushed, a recursive controller termination could occur (termination code 0x03030102). • Resolved a recursive controller termination that could result if a controller restart occurred during deletion of a DR group (termination code 0x4238011f). • Enhanced the interlocking mechanism for the group online request in an HP Continuous Access EVA configuration to ensure that the group failover is allowed to occur on only one controller to prevent a controller termination (termination code 0x0442011f). • Added a verification step to ensure that adequate space exists on the destination array prior to a LUN expansion to prevent a repeated controller termination. • Fixed an issue that caused a controller termination when operations were prevented on unpresented copies (snapshots, snapclones, mirrorclones) and the parent virtual disk was a DR group member (termination code 0x04d3011f). • Addressed an issue where an incomplete transition of a DR group between controllers led to a repeated termination. • Fixed a controller termination that occurred when a snapshot was part of a DR group and there was a controller restart, resulting in the snapshot and its source being on a different controller than the DR group. • Addressed an issue where an error indicator was incorrectly set in a DR group log leading to a controller termination (termination code 0x075b0104). • Fixed a controller termination that occurred when trying to delete a DR group member while the disk group is inoperative. • Fixed a controller termination (termination code 0x0402011f) that occurred during failover to the destination array during a controller software upgrade. • Fixed an issue which could result in deletion of all DR group members due to an incomplete online state on the destination controller. • Fixed a dual controller termination (termination code 0x02000100) that occurred due to multiple mastership transitions of DR groups.

HP Continuous Access EVA
This section describes issues affecting HP Continuous Access EVA implementations of remote replication,
including data replication (DR) groups.
Resolved a recursive controller termination that could occur if, during a DR failover from one array
to another, the failover array has only one active controller, resulting in cached information that
is not copied to the restarted partner controller. When the restarted controller became the master
controller prior to the cached work being flushed, a recursive controller termination could occur
(termination code
0x03030102
).
Resolved a recursive controller termination that could result if a controller restart occurred during
deletion of a DR group (termination code
0x4238011f
).
Enhanced the interlocking mechanism for the group online request in an HP Continuous Access
EVA configuration to ensure that the group failover is allowed to occur on only one controller to
prevent a controller termination (termination code
0x0442011f
).
Added a verification step to ensure that adequate space exists on the destination array prior to a
LUN expansion to prevent a repeated controller termination.
Fixed an issue that caused a controller termination when operations were prevented on unpresented
copies (snapshots, snapclones, mirrorclones) and the parent virtual disk was a DR group member
(termination code
0x04d3011f
).
Addressed an issue where an incomplete transition of a DR group between controllers led to a
repeated termination.
Fixed a controller termination that occurred when a snapshot was part of a DR group and there
was a controller restart, resulting in the snapshot and its source being on a different controller than
the DR group.
Addressed an issue where an error indicator was incorrectly set in a DR group log leading to a
controller termination (termination code
0x075b0104
).
Fixed a controller termination that occurred when trying to delete a DR group member while the
disk group is inoperative.
Fixed a controller termination (termination code
0x0402011f
) that occurred during failover to
the destination array during a controller software upgrade.
Fixed an issue which could result in deletion of all DR group members due to an incomplete online
state on the destination controller.
Fixed a dual controller termination (termination code
0x02000100
) that occurred due to multiple
mastership transitions of DR groups.
Operating system/solution support
This section describes issues affecting EVA support of operating systems or solutions.
Use of XCS 09534000 with Veritas Storage Foundations and IO Fencing is now supported.
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 unexpected resynchronization between controllers, which occurred during the I/O
module firmware upgrade.
Fixed an issue which caused controllers to appear unresponsive after a controller software upgrade.
Fixed an issue that prevented a replacement controller from downgrading the controller software
version to the version running on the other controller.
