Problem: Cannot initialize or create a Storwize V7000 Gen2
clustered system
Use this information if your attempt to create a Storwize V7000 Gen2 clustered
system failed.
The failure is reported regardless of the method that you used to create a system:
v System initialization wizard (using the technician port of a node canister)
v USB flash drive
v Management console
v Service assistant
v Service command line
To prevent accidental loss of volumes, a system cannot be initialized on an
enclosure that is already configured in an existing system. Check the following
details using the service assistant to confirm that the enclosure is not already
configured in a system:
v The node canister that you are attempting to create a clustered system on must
be in candidate state.
v The partner node canister in the control enclosure must not be in active state.
v The latest system ID of the control enclosure must be 0. If the partner node is in
active state, see Start here: Use the management GUI recommended actions. If
the partner code is not in the active state and the node canister on which you
are attempting to create the system is not in service state, see "Procedure: Fixing
node errors" on page 271.
Problem: Cannot initialize or create a Storwize V7000 Gen1
clustered system
If your attempt to create a system has failed, there are several possible solutions
depending on the current state of the storage system.
Note: This clustered storage system is different from the file system cluster on the
file modules.
