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

Workarounds
This section identifies important notes and workarounds for the EVA4400, EVA6400, and EVA8400.
Hardware and controller software
Controller logs possibly retrieved incorrectly after upgrading to XCS 0950xxxx on the EVA4400
After upgrading the EVA4400 to XCS 0950xxxx, HP Command View EVA might not retrieve the
controller logs correctly. This occurs if the controller event log sequence number is reset to zero during
the upgrade. When the controller logs are not being retrieved, controller log-related entries will not
be sent to the Windows application event log nor will the related WEBES callouts and SNMP traps
be sent.
To determine if this issue has occurred after the upgrade, access the HP Command View EVA GUI
and select View events > Controller Event Log. Compare the most recent value in the Sequence # box
in the GUI to the values in the \Program Files\Hewlett-Packard\Sanworks\Element
Manager for StorageWorks HSV\cache\[EVA WWN]\[EVA WWN].sceventstatefile.txt.
The [EVA WWN].sceventstatefile.txt file stores the last sequence number retrieved from
the controller event log in the second value. If the second value in the [EVA
WWN].sceventstatefile.txt file is larger then the value shown in the GUI, apply the following
workaround:
1. Stop the HP Command View EVA service.
2. Rename the \Program Files\Hewlett-Packard\Sanworks\Element Manager for
StorageWorks HSV\cache\[EVA WWN] directory to ...\[EVA WWN]_OLD.
3. Start the HP Command View EVA service.
HP Command View EVA will retrieve the controller log events that have occurred since the
controller software upgrade.
If the controller log events from prior to the upgrade are needed, you must retrieve them from the
previous ...\[EVA WWN]_OLD directory.
After applying the workaround, for those controller log-related events that have not been retrieved
prior to the workaround, WEBES callouts and SNMP traps may be sent if the configured rules apply.
Allow this to occur so you can be notified of any important events. For events older than one week,
WEBES will roll all the related events into one callout.
Using the 10.x.x.x network with the management module (EVA4400 only)
If the management module is configured in the 10.x.x.x network, do not use 10.0.0.0, 10.0.0.1,
10.0.0.2, or 10.0.0.3 as the IP address for the management module or any device connected to the
management module. These IP addresses are used by the management module.
Managing unused ports
When you have unused ports on an EVA, perform the following steps:
1. Place a loopback plug on all unused ports.
2. Change the mode on unused ports from fabric to direct connect.
