expand vdisk
Description
Adds disks to a vdisk to expand its storage capacity. This command applies to linear storage only.
The new disks must be the same type as disks already in the vdisk and should also have the same
capacity.
NOTE:
If you upgraded from an earlier release that did not distinguish between enterprise and
midline SAS disks, you might have vdisks that contain both types of disks. For those vdisks, you can
designate either or both types of disks for expansion. If—through replacement of spares or failed
disks—the vdisk is changed to contain only one type of disk, you will only be able to add disks of
that type to the vdisk.
The expansion capability for each supported RAID level is:

Cannot expand.
Can add 1–4 disks at a time.
Cannot expand.
Can add 2 or 4 disks at a time.
Can expand the vdisk one RAID-5 sub-vdisk at a
time. The added RAID-5 sub-vdisk must contain
the same number of disks as each original
sub-vdisk.

IMPORTANT:
Vdisk 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 vdisk utilities are running on the vdisk. If another
operation is in progress, the expansion cannot start.
