CLI Guide

• When set to the default spare capacity, the system will try to replenish spare capacity to be the sum of

the two largest disks in the group.

• When default spare capacity has been overridden (via the set vdisk on page 156 adapt-target-

spare-capacity parameter), the system will try to replenish spare capacity to meet the configured

target GiB.

• If the actual spare capacity meets the target spare capacity, the new disk capacity will be allocated to

user data.

NOTE: Disk group expansion cannot be stopped and can take days to complete, depending on

disk type, RAID level, and other factors.

Before starting the expansion, ensure no other utilities are running on the disk group. If another operation is in

progress, the expansion cannot start.

Syntax

disks disks

[prompt yes|no]

vdisk

Parameters disks disks

The IDs of the disks to add. For disk syntax, see Command syntax on page 17.

prompt yes|no

Optional. For scripting, this specifies an automatic reply to confirmation prompts:

• yes: Allow the command to proceed.

• no: Cancel the command

If this parameter is omitted, you must manually reply to prompts.

vdisk

The name or serial number of the linear disk group to expand. A name that includes a space must be enclosed

in double quotes.

Examples Expand linear disk group VD1 to include disk 1.11.

# expand vdisk disks 1.11 VD1

Expand a RAID-10 linear disk group named R10 to include an additional mirror pair.

# expand vdisk disks 2.9-10 R10

Expand a RAID-50 linear disk group named R50, which has four 3-disk subgroups, to include an additional

subgroup.

# expand vdisk disks 2.1-2,2.5 R50

Add 10 disks to ADAPT disk group Data3.

# expand disk-group disks 1.1-10 Data3
