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.
disk-group
The name or serial number of the disk group to expand. A name that includes a space must be
enclosed in double quotes.
Examples Expand disk group DG1 to include disk 1.11.
# expand disk-group disks 1.11 DG1
Expand a RAID-10 disk group named R10 to include an additional mirror pair.
# expand disk-group 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 disk-group disks 2.1-2,2.5 R50
Add 10 disks to ADAPT disk group Data3.
# expand disk-group disks 1.1-10 Data3

Description
Adds disks to a linear disk group to expand its storage capacity.
The new disks must be the same type as disks already in the disk group. The disks need not have
consistent capacity; ADAPT will use whatever space is available.
NOTE: If you upgraded from an earlier release that did not distinguish between enterprise and
midline SAS disks, you might have disk groups that contain both types of disks. For those groups,
you can designate either or both types of disks for expansion. If—through replacement of spares
or failed disks—the disk group is changed to contain only one type of disk, you will only be able to
add disks of that type to the disk group.
NOTE: A disk group can contain a mix of 512-byte native sector size (512n) disks and 512-byte
emulated sector size (512e) disks. For consistent and predictable performance, do not mix disks
of different sector size types (512n, 512e).
The expansion capability for each supported RAID level is:
RAID level Expansion capability Maximum disks
NRAID Cannot expand. 1
0, 3, 5, 6 Can add 1–4 disks at a time. 16
1 Cannot expand. 2
10 Can add 2 or 4 disks at a time (linear storage). 16
50
Can expand the disk group one RAID-5 subgroup
at a time. The added RAID-5 subgroup must
