ONTAP 9.14.1 commands

storage disk zerospares

Zero non-zeroed spare disks

Availability: This command is available to cluster administrators at the admin privilege level.


The storage disk zerospares command zeroes all non-zeroed spare disks in all nodes or a specified node in the cluster. A node must be online to zero disks. This operation must be done before a disk can be reused in another aggregate. This version of ONTAP uses fast zeroing, which converts a spare disk from non-zeroed to zeroed without the long wait times required when physically zeroing a disk.


[-owner {<nodename>|local}] - Owner

If this parameter is specified, only non-zeroed spares assigned to the specified node will be zeroed. Otherwise, all non-zeroed spares in the cluster will be zeroed.


The following example zeroes all non-zeroed spares owned by a node named node4, using fast zeroing:

cluster1::> storage disk zerospares -owner node4
