How to identify if a cache disk is really faulted and which head of a cluster a cache disk belongs to.
A 'faulted' status on a (readzilla) cache disk can happen on 7x10, 7x20, ZS3-x & ZS4-x clustered configurations.
Some takeover/failback operations have been performed earlier.
The cluster is working fine, but some or all of the cache disks remain in a faulted status.
This might cause performance issues on the cluster heads.
