storage disk option modify

Modify disk options

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

Description

The storage disk option modify command modifies the background firmware update setting, automatic copy setting, automatic disk assignment of all disks assigned to a specified node, or modifies the setting of automatic disk assignment of unowned disks at a shelf level granularity.

Parameters

-node {<nodename>|local} - Node

This parameter specifies the node that owns the disks whose options are to be modified.

[-bkg-firmware-update {on|off}] - Background Firmware Update

This parameter specifies whether firmware updates run as a background process. The default setting is on, which specifies that firmware updates to spare disks and file system disks is performed nondisruptively via a background process. If the option is turned off, automatic firmware updates occur at system startup or during disk insertion.

[-autocopy {on|off}] - Auto Copy

This parameter specifies whether data is to be automatically copied from a failing disk to a spare disk in the event of a predictive failure. The default setting is on. It is sometimes possible to predict a disk failure based on a pattern of recovered errors that have occurred. In such cases, the disk reports a predictive failure. If this option is set to on, the system initiates Rapid RAID Recovery to copy data from the failing disk to an available spare disk. When data is copied, the disk is marked as failed and placed in the pool of broken disks. If a spare is not available, the node continues to use the disk until it fails. If the option is set to off, the disk is immediately marked as failed and placed in the pool of broken disks. A spare is selected and data from the missing disk is reconstructed from other disks in the RAID group. The disk does not fail if the RAID group is already degraded or is being reconstructed. This ensures that a disk failure does not lead to the failure of the entire RAID group.

[-autoassign {on|off}] - Auto Assign

This parameter specifies whether automatic assignment of unowned disks is enabled or disabled. The default setting is on. When on, the default behavior is to automatically assign disks at the adapter (stack) level of granularity. If all assigned disks on an adapter (stack) have the same ownership assignment, and there are unowned disks present on that adapter (stack), automatic assignment will assign the unowned disks to match the ownership of the already assigned disks on that adapter (stack). This parameter is used to set both a node-specific and a cluster-wide disk option.

[-autoassign-shelf {on|off}] - Auto Assignment At Shelf Level

This parameter specifies whether automatic assignment of unowned disks should be done at the shelf level of granularity or not. This parameter is ignored if autoassign parameter is off. Otherwise, if both autoassign and autoassign-shelf parameters are on, then if there are unowned disks on a shelf and all assigned disks on that shelf have the same ownership assignment, automatic assignment will assign the unowned disks to match the ownership of the already assigned disks on that shelf. The default setting is off. This parameter is used to set both a node-specific and a cluster-wide disk option.

Examples

The following example sets the background firmware update setting to on for all disks belonging to a node named node0:
cluster1::> storage disk option modify -node node0 -bkg-firmware-update on
