disk-fail | [top]

> Fail a file system disk. Removes the specified file system disk from the RAID configuration, spinning the disk down when removal is complete. disk fail is used to remove a file system disk that may be logging excessive errors and requires replacement. Note that if optional input parameter 'is-immediate' is true, the specified disk will be immediately failed out, and the RAID group to which the disk belongs will enter degraded mode (meaning a disk is missing from the RAID group). If a spare disk at least as large as the disk being removed is available, the contents of the disk being removed will be reconstructed onto that spare disk. If 'is-immediate' options is false or not specified, system will prefail the disk and its content will be copied to a replacement disk if a suitable spare disk is available, and afterwards the prefailed disk will be failed out. This process can be observed by polling disk-list-info for this disk and tracking values of elements copy-destination and copy-percent. Same can be done using 'storage-disk-get-iter' when requested from Admin Vserver LIF. The disk being failed is marked as ``broken'', so that if it remains in the disk shelf, it will not be used by the filer as a spare disk. If the disk is moved to another filer, that filer will use it as a spare. This is not a recommended course of action, as the reason that the disk was failed may have been because it needed to be replaced. 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 fail, e.g. "v0.1". On Admin Vserver LIF, this will be disk path name with format of ":". e.g. "Filer01:v0.1"
> is-immediate |  | boolean optional | Specify 'true' if disk is to be failed out immediately. If disk is to be prefailed, specify 'false'. Default value is 'false'.

disk-remove | [top]

> 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-unfail | [top]

> 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"
> make-spare |  | boolean optional | Specify 'true' to force the disk to become a spare upon unfail. Default value is 'false'.

> Errno | Description
> EINTERNALERROR |  |
> EDISKNOTFOUND |  |

disk-update-disk-fw | [top]

> 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.

> Errno | Description
> EINTERNALERROR |  |
> EDISKNOTFOUND |  |
> EINVALIDINPUTERROR |  |
> ENODENOTFOUND |  |

disk-zero-spares | [top]

> 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.

> Errno | Description
> EINTERNALERROR |  |

> home |  | string optional | The home of the disk. On NG will be different than owner if the home node has been taken over. On Classic this will be the same as owner. If the disk has no owner, this will not be returned.
