You create a logical volume from an extent pool in a rank group. The logical volume is also a member of a logical subsystem group. The logical subsystem group identifier and the rank group identifier of the extent pool that you specify must be identical. Even-numbered logical subsystem identifiers are associated with rank group identifier 0, and odd-numbered logical subsystem identifiers are associated with rank group identifier 1.
Retry the create volume task and specify an extent pool and a logical subsystem group that are in the same rank group.
