Possible Cause
Corrective Action
The management server may not be able
to communicate with either controller.
Check the connection configuration between the management
server and the controller pair. The management server must have
a communication path to both controllers in case one controller
loses communications with the server.
When HP Command View EVA is first
starting up, a password may be enabled
on the controllers, but a password has
not been e ntered in HP Command View
EVA.
Enter the correct password through HP Command View EVA or
disable the password on the controller.
The switche
s may not be correctly zoned,
making a st
orage system invisible to HP
Command Vi
ew EV A.
Verify that switches are zoned correctly.
HP Command View EVA may have
been restarted while there was a
communication failure between HP
Command View EVA and the controllers.
When restart is completed, the storage
system that lost communication will not
be visible.
1. Verify that the controllers are up and functioning properly.
2. Check the cable connections bet ween the management server
and the switch.
3. Verify that switch zoning is correct.
4. Click Discover.
A storage system may not be visible
to HP Command View EVA because
the controllers are waiting for World
Wide ID (WWID) to be entered. This
condition will occur if the storage system
has been uninitialized and the cabinet
is power cycled.
This may also occur if backend problems
arepreventingaccesstothequorum
drives. Once communication is restored,
the WWID along with the checksum
can be re-entered.
Enter the WWID.
Solving security credentials configuration problems
The following Windows-based security groups are required on the management server:
NOTE:
Group names are case sensitive.
