Adding Space to a LUN
To add unused, available space in an array to a specific LUN:
Basic Command
EXTEND UNIT
Example Command
CLI> EXTEND UNIT 2 ADD_SIZE=1000MB
Command Options
2—the LUN to which the space will be added. In this example, LUN 2 is
being extended.
ADD_SIZE=1000MB—how much of the available space in the array to add to
the LUN. In this example, 1000 MB of space will be added. The size limit
must be specified as GB, MB, or KB. If no size is specified, the maximum
available space of the included disks will be assigned to the array.
NEW_SIZE=xxxxyy—can be used instead of ADD_SIZE to enter the total new
size of the LUN, where xxxx represents the size and yy indicates GB, MB, or
KB.
Example CLI Response
The actual new volume size will be 1992MB.
Unit 2 is being extended.
Use “show unit 2” to monitor progress.
