HP StorageWorks Enterprise Virtual Array release notes (XCS 09501200) (5697-0013, June 2009)

Certain menu selections cause the OCP to go blank
After changing the topology for a host port or checking status with the primary controller, the display
window of the OCP on the secondary controller goes blank. To fix this issue, “replug” the OCP as
follows:
1. Remove the front panel of the controller by grasping the panel at each end and pulling it off of
the controller.
2. Press the OCP latch and swing the panel out until it is fully open.
CAUTION:
Handle the OCP by its metal frame only. This will ensure that the electronic components are
not damaged by electrostatic charge.
3. Grasp the OCP by its metal frame and pull it halfway out of the enclosure.
4. Re-insert the OCP into the enclosure.
5. Close the OCP until it latches.
6. Reinstall the front panel of the controller, pressing it firmly into the place.
Powering off storage system components
Individual EVA storage array components should not be powered off during normal operation. Before
powering off any storage system component, contact your HP-authorized service representative for
assistance.
Controller port becomes unresponsive after failure of redundant controller
After an HSV300-S controller failure in an EVA4400 connected to a Linux host, the front-end port on
the redundant controller can become unresponsive. HP is working to resolve this issue. For the supported
operating system and HBA driver versions, see the latest HP HBA driver release notes.
EVA4400 port does not log in to the embedded switch
It has been observed that an EVA4400 host port will occasionally not log in to the embedded switch.
It is believed that this condition occurs if the port does not negotiate to the proper speed setting. If
you encounter this issue, restart the controller to bring the port online. HP is continuing to investigate
this issue.
DR log progress bar percentage appears incorrect
Because the DR log can suddenly reach the full copy threshold, the percentage complete displayed
by HP Command View EVA can appear to be an inaccurate. This is caused by overhead (or metadata)
that is applied to the file and is included in the percent complete, which reduces the amount of capacity
available. This overhead is more significant for smaller log files than larger log files because some
of the overhead is constant in size. For example, a 5 GB minimum log size can contain 35 percent
overhead, while a 40 GB log file might only contain 10 percent overhead. This could cause the
progress bar in HP Command View EVA to show a larger amount of progress than one would expect
for the allocated log size.
