• Corrected the ability to set the device ID on presented LUNs. • Improved the ability to read from a mirrored pair when a data error bit is set on one of the one volumes. • Changed the disk drive inquiry process to occur as soon as the disk drive is added to loop. Hardware (replaceable parts, device ports, resynchronization) This section describes issues affecting physical hardware, which can lead to incorrect condition handling, false condition reporting and similar events that may lead to incorrect device status reporting or replacement. • A false Over Temperature condition could lead to a disk enclosure shutdown. • On the EVA4400, false reporting of the battery holdup time caused a change to the LUN cache policy. • Excessive exchange timeouts (the cause of which has been corrected) led to device ports being disabled. • Incorrectly formed Linux device mapper RAID (DM RAID) requests caused excessive server boot time due to timeouts. • On the EVA8400, repeated cache battery failures due to a persistent load testing state were cor- rected. • On the EVA4400, the time to establish mirror port communication (after a single controller resyn- chronization) has been improved. • Corrected false failure indications on the controller's replaceable components that occurred after a controller resynchronization. HP Business Copy EVA This section describes issues affecting HP Business Copy EVA implementations of local replication, including snapshots, snapclones, and mirrorclones. • Improvements were made to prevent a recursive controller termination that occurred when a mirrorclone was created and fractured in a different disk group than the source virtual disk and an inoperative condition occurred on the source. • For multi-attach configurations, the timing requirements have been improved to satisfy the Microsoft Volume Snapshot Service (VSS) requirements. HP Continuous Access EVA This section describes issues affecting HP Continuous Access EVA implementations of remote replication, including data replication (DR) groups. • During a migration from an EVA3000/5000 running VCS 3.xxx to an EVA4400 or EVA6400/8400, a controller termination (termination code 0x0442011f) occurred if the target EVAx4000 had existing DR groups with another EVA model communicating on the same Fibre Channel port. This problem has been corrected in this release. • Addressed an issue where a heavy mirrored workload caused by DR operations led to a controller termination (termination code 0x0442011f). • Improved preferred port settings to ensure paths are returned consistently to the desired controller in HP Continuous Access EVA configurations. • In an HP Continuous Access EVA configuration, a correction was made to prevent a controller termination when commands are received out of sequence across mirror ports (termination code 0x0c0e0106). • Improved support for the creation of DR groups that have an initial log size greater than 100 GB.

Hardware (replaceable parts, device ports, resynchronization)
This section describes issues affecting physical hardware, which can lead to incorrect condition
handling, false condition reporting and similar events that may lead to incorrect device status reporting
or replacement.
•
A false Over Temperature condition could lead to a disk enclosure shutdown.
•
On the EVA4400, false reporting of the battery holdup time caused a change to the LUN cache
policy.
•
Excessive exchange timeouts (the cause of which has been corrected) led to device ports being
disabled.
•
Incorrectly formed Linux device mapper RAID (DM RAID) requests caused excessive server boot
time due to timeouts.
•
On the EVA8400, repeated cache battery failures due to a persistent load testing state were cor-
rected.
•
On the EVA4400, the time to establish mirror port communication (after a single controller resyn-
chronization) has been improved.
•
Corrected false failure indications on the controller's replaceable components that occurred after
a controller resynchronization.
HP Business Copy EVA
This section describes issues affecting HP Business Copy EVA implementations of local replication,
including snapshots, snapclones, and mirrorclones.
•
Improvements were made to prevent a recursive controller termination that occurred when a mir-
rorclone was created and fractured in a different disk group than the source virtual disk and an
inoperative condition occurred on the source.
•
For multi-attach configurations, the timing requirements have been improved to satisfy the Microsoft
Volume Snapshot Service (VSS) requirements.
HP Continuous Access EVA
This section describes issues affecting HP Continuous Access EVA implementations of remote replication,
including data replication (DR) groups.
•
During a migration from an EVA3000/5000 running VCS 3.xxx to an EVA4400 or
EVA6400/8400, a controller termination (termination code
0x0442011f
) occurred if the target
EVAx4000 had existing DR groups with another EVA model communicating on the same Fibre
Channel port. This problem has been corrected in this release.
•
Addressed an issue where a heavy mirrored workload caused by DR operations led to a controller
termination (termination code
0x0442011f
).
•
Improved preferred port settings to ensure paths are returned consistently to the desired controller
in HP Continuous Access EVA configurations.
•
In an HP Continuous Access EVA configuration, a correction was made to prevent a controller
termination when commands are received out of sequence across mirror ports (termination code
0x0c0e0106
).
•
Improved support for the creation of DR groups that have an initial log size greater than 100 GB.
