Workarounds This section identifies important notes and workarounds for the EVA4400, EVA6400, and EVA8400. If you encounter difficulties with the workarounds, contact HP Services for assistance. Hardware and controller software Setting the controller power on behavior In the HP P6000 Control Panel online help and user guide, the "Controller power on behavior" and "Setting controller power on behavior" sections describe the new HP P6000 Control Panel feature that can be set so that the array boots up automatically when power is applied after a full shutdown. To further clarify this feature: • If this feature is disabled and you turn on power to the array from the rack power distribution unit (PDU), only the disk enclosures boot up. With this feature enabled, the controllers will also boot up, making the entire array ready for use. • If, after setting this feature, you remove the management module from its slot and reinsert it to reset power or you restart the management module from the HP P6000 Control Panel, only the controllers will automatically boot up after a full shutdown. In this scenario, you must ensure that the disk enclosures are powered up first; otherwise, the controller boot up process may be interrupted. • After setting this HP P6000 Control Panel feature, if you have to shut down the array, perform the following steps: 1. Use HP P6000 Command View to shut down the controllers and disk enclosures. 2. Turn off power from the rack power distribution unit (PDU). 3. Turn on power from the rack PDU. After startup of the management module, the controllers will automatically start. Stale Inquiry data issue after SSD firmware upgrade After upgrading disk drive firmware on solid state disk drives, HP P6000 Command View may indicate that the upgrade was successful, but the disk drive properties page does not reflect the upgraded firmware version. To resolve this issue: 1. Upgrade the disk drive again. 2. Wait 10 minutes before checking the disk drive properties page to verify the correct firmware version is displaying. 3. If the problem persists, contact HP Support Engineering. Disk group occupancy allocation notification received on non-thin provisioned virtual disks After expanding or shrinking a virtual disk, if the action exceeds the occupancy alarm level setting (either warning or critical), you may receive notification from P6000 Command View events and Insight Remote Support notifications. These events and notifications may be received even if the affected virtual disk is not a thin provisioned virtual disk. All notification alarms should be investigated and when it is determined that they apply to non-thin provisioned virtual disks, the alarm may be safely ignored. Data Replication Protocol changes after controller software upgrade In an HP P6000 Continuous Access configuration, the Data Replication Protocol may change to HP SCSI FC Compliant Data Replication Protocol when the array being upgraded to XCS 10001000 is: • An EVA4400 that was initialized at a controller software version earlier than XCS 09500000 • An EVA6400 or EVA8400 that was upgraded from an EVA4400 (data in place upgrade) and was initialized at a controller software version earlier than XCS 09500000. 12 Workarounds

Hardware and controller software
Setting the controller power on behavior
In the HP P6000 Control Panel online help and user guide, the “Controller power on behavior” and
“Setting controller power on behavior” sections describe the new HP P6000 Control Panel feature that
can be set so that the array boots up automatically when power is applied after a full shutdown. To
further clarify this feature:
•
If this feature is disabled and you turn on power to the array from the rack power distribution unit
(PDU), only the disk enclosures boot up. With this feature enabled, the controllers will also boot
up, making the entire array ready for use.
•
If, after setting this feature, you remove the management module from its slot and reinsert it to
reset power or you restart the management module from the HP P6000 Control Panel, only the
controllers will automatically boot up after a full shutdown. In this scenario, you must ensure that
the disk enclosures are powered up first; otherwise, the controller boot up process may be
interrupted.
•
After setting this HP P6000 Control Panel feature, if you have to shut down the array, perform
the following steps:
1.
Use HP P6000 Command View to shut down the controllers and disk enclosures.
2.
Turn off power from the rack power distribution unit (PDU).
3.
Turn on power from the rack PDU.
After startup of the management module, the controllers will automatically start.
Stale Inquiry data issue after SSD firmware upgrade
After upgrading disk drive firmware on solid state disk drives, HP P6000 Command View may indicate
that the upgrade was successful, but the disk drive properties page does not reflect the upgraded
firmware version.
To resolve this issue:
1.
Upgrade the disk drive again.
2.
Wait 10 minutes before checking the disk drive properties page to verify the correct firmware

virtual disk is not a thin provisioned virtual disk. All notification alarms should be investigated and
when it is determined that they apply to non-thin provisioned virtual disks, the alarm may be safely

Data Replication Protocol changes after controller software upgrade
In an HP P6000 Continuous Access configuration, the Data Replication Protocol may change to HP
SCSI FC Compliant Data Replication Protocol when the array being upgraded to XCS 10001000 is:
•
An EVA4400 that was initialized at a controller software version earlier than XCS 09500000
•
An EVA6400 or EVA8400 that was upgraded from an EVA4400 (data in place upgrade) and
was initialized at a controller software version earlier than XCS 09500000.
