Recovering volumes in shared disk groups
Volumes can only be recovered on the master node.
The vxrecover utility is used to recover plexes and volumes after disk replacement.
When a node leaves a cluster, it can leave some mirrors in an inconsistent state.
The vxrecover utility can be used to recover such volumes. The -c option to
vxrecover causes it to recover all volumes in shared disk groups. The vxconfigd
daemon automatically calls the vxrecover utility with the -c option when
necessary.
