expand -volume
Use the expand -volume command to expand the capacity of a volume. The new
capacity of a volume is equal to the added capacity increment plus the old volume.
The incremental capacity can be defined in MB, GB or the percentage (%) of the
total remaining drive pool capacity.
Note: If the remaining capacity on the pool is less than the requested expansion,
an error occurs.
Command arguments:
<CLI> expand -volume poolname:volumename -add capacityIncrement [MB|GB|%]
Where:
v poolname:volumename - Allows selection of the volume name as a combination of
poolname and volumename.
v capacityIncrement - Specifies the number for the incremental capacity.
