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 contain
the same number of disks as each original subgroup
32
ADAPT Can add up to 68 disks at a time 128
When disks are added to an ADAPT disk group, the system will first replenish any spare capacity needed to
be fully fault-tolerant, then use the remainder or expansion of user data capacity.
