Toggle the locator LED for this disk device. If the device LED is currently on, then this indicator will flash.
Online image:icon indicating an item is online or rejoining a cluster
Offline the disk. This option is only available for disks that are part of a configured storage pool (including the system pool). Offlining a disk prevents the system from reading or writing to it. Faulted devices are already avoided, so this option should only be required if a disk is exhibiting performance problems that do not result in pathological failure. It is not possible to offline a disk that would prevent access to data (i.e. offlining both halves of a mirror). If the device is an active hot spare, this will also give the option of detaching the hot spare completely. Once a hot spare is detached, it cannot be activated except through another fault or hotplug event.

Note -  Do not perform a pool configuration operation while a disk firmware upgrade is occurring. To check if an upgrade is in progress, navigate to Maintenance > System in the BUI, or maintenance system updates in the CLI.
