storage disk zerospares

Zero non-zeroed spare disks

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

Description

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.

Parameters

[-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.

Examples

The following example zeroes all non-zeroed spares owned by a node named node4, using fast zeroing:
cluster1::> storage disk zerospares -owner node4
The following example zeroes all non-zeroed spares owned by a node named node2 by physically writing zeros to the entire disk:
cluster1::> storage disk zerospares -owner node2 -use-physical-zeroing
