Problem Summary: If an EMC SRDF device group whose replica pair is split attempts to switch the device group over to another node, the switchover fails. Furthermore, the device group is unable to come back online on the original node until the replica pair has been returned to a paired state.
Workaround: Verify that SRDF replicas are not split before you attempt to switch the associated Oracle Solaris Cluster global-device group to another cluster node.
