Remove a spare disk. Removes the specified spare disk from the RAID configuration, spinning the disk down when removal is complete. You can use disk remove to remove a spare disk so that it can be used by another filer (as a replacement for a failed disk or to expand file system space). NOTE: Data ONTAP 7.0 and earlier releases don't indicate failure code properly.

Input Name	Range	Type	Description
disk		string	Name of the disk to remove, e.g. "v0.1". On Admin Vserver LIF, this will be disk path name with format of ":Disk Name". e.g. "Filer01:2a.32"

disk		string optional	Name of disk to assign. Wildcarding for disk string is supported.

Input Name	Range	Type	Description
force		boolean optional	Force flag need to be set to 'true' if reassigning disks which are owned by another Filer. However, if that Filer is up and has put a reservation on the disk, even the force option won't work. In this case reassign will need to be run on the Filer which owns the disks.

Unfail a disk in the broken pool, by clearing its FDR (Failed Disk Registry) entry and unfailing it at the Storage Layer, as necessary. If the "make-spare" option is set to B_TRUE, the disk is returned to the spare pool. Otherwise, label assimilation will bring the disk back according to its on-disk labels, with one of four possible outcomes. 1. Disk becomes a spare. This is the common case. The disk becomes a spare upon unfail, because its parent volume is complete and online. 2. Disk is assimilated into former volume. This is a recovery scenario. The disk is brought back into an existing volume, which may result in this volume coming back online. 3. Disk is assimilated into a new partial volume. This may occur in the rare case that the disk's former volume was destroyed or moved. 4. Disk returned to broken pool. This is the case if a fatal error occurs in process of unfailing the disk.

Input Name	Range	Type	Description
disk		string	Name of the disk, e.g. "v0.1". On Admin Vserver LIF, this will be disk path name with format of ":Disk Name". e.g. "Filer01:2a.32"

EDISKNOTFOUND

Start disk firmware download process to update firmware on disks. This operation is asynchronous, and therefore returns no errors that might occur during the download process. This operation will only update firmware on disks that do not have the latest firmware revision. The firmware revision on the disk can be monitored via the disk-list-info API.

Input Name	Range	Type	Description
disk-list		disk-name[] optional	List of disks to be updated. If not specified, all disks are updated. Example: 4a.18 5b.16 switch1:10.126L4
node-name		string	This field is only valid when the request is sent to the Admin Vserver LIF. This is the storage system name the command will be executed on.

Set up all non-zeroed spares owned by the filer to start zeroing. This operation is asynchronous, and therefore returns no errors that might occur when the zeroing operation actually starts, which could be several seconds after this API operation completes. Zeroing progress can be monitored via the disk-list-info API. Same can be done using 'storage-disk-get-iter' when requested from Admin Vserver LIF. The "zeroing-percent" element of disk-detail-info is returned if disk zeroing has started, and "is-zeroed" returns TRUE once the zeroing has completed (or, if zeroing wasn't necessary in the first place).

Input Name	Range	Type	Description
node-name		string optional	Name of the node on which spare disks to be zeroed When requested from Admin Vserver LIF and node name is not specified, spare disks from all nodes in the cluster will be zeroed.
