How to identify if a cache disk is really faulted and which head of a cluster a cache disk belongs to.

Symptoms

To discuss this information further with Oracle experts and industry peers, we encourage you to review, join or start a discussion in the My Oracle Support Community - Disk Storage ZFS Storage Appliance

A 'faulted' status on a (readzilla) cache disk can happen on 7x10, 7x20, ZS3-x & ZS4-x clustered configurations.

 

Changes

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.
