Symptoms

PCA could experience NFS outages after upgrading the ZFS firmware with below scenario:

• Customer has created a network of type storage_network using the PCA admin command 'create network <name> storage_network.'
• ovcasn02r1 was the active cluster head at the time of creation of the storage_network.
• The resulting vnic on the ZFS that is created by the command shows 'owner = ovcasn02r1.'
• Customer created NFS share(s) with PCA admin command 'create nfs-storage' that use this network. By default, the share(s) end up in OVCA_POOL -> VMINTERNAL, which already has 'owner = ovcasn01r1.'
• This discrepancy will be enforced by AK version >= 8.8.30 and must be remedied, or VMs that rely on these NFS share(s) might suddenly see NFS failures after the ZFS firmware is upgraded to >= 8.8.30.

This 2.4.4.1 pre-check will flag any storage network interfaces that have 'owner = ovcasn02r1' so the customer can manually correct the owner to 'ovcasn01r1' before proceeding with the upgrade.
