Oracle Solaris ZFS Administration Guide

Taking a Device Offline

You can take a device offline by using the zpool offline command. The device can be specified by path or by short name, if the device is a disk. For example:

# zpool offline tank c1t0d0
bringing device c1t0d0 offline

Consider the following points when taking a device offline:

Offline devices are in the OFFLINE state when you query pool status. For information about querying pool status, see Querying ZFS Storage Pool Status.

For more information on device health, see Determining the Health Status of ZFS Storage Pools.
