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

Description

The command storage aggregate show-spare-disks displays information about spare disks. The command output depends on the parameter or parameters specified with the command. If no parameters are specified, the command displays information about all spare disks in the cluster.

Parameters

Shared disks have partitions that allow them to be used in multiple aggregates and between nodes in an HA pair. When set to true , this parameter selects shared disks in which the root partition and/or the data partition is a spare. When set to false only spare disks without partitions are displayed. When this parameter is not used, all spare disks are displayed.

[-is-disk-offline {true|false}] - Is Disk Offline?

Selects the spare disks that match this parameter value.
