NetApp Cluster Model: ?
Ontap version : ?
Are the spare disks assigned to the Nodes of the cluster?

Check if there are any 'unowned' disk:
::> storage disk show -spare

Info: If the cluster has partitioned disks.
::> storage aggregate show-spare-disks

You can go to each node in the cluster and check if there are any unassigned disks.
::> node run -node cluster-01
cluster-01> disk show -n
disk show: No unassigned disks

Share this output as well for each Node:

cluster-01> sysconfig -r

Hi,

This is E-Series with SANtricity. Could you please provide the SMcli commands that I need to run to collect the info?

Thanks!
