Modifying Arrays and LUNs
Occasionally, after an array or a LUN has been created, its characteristics need to
be changed. The following changes can be made:
■ Adding Drives to an Array
■ Adding Space to a LUN
■ Changing the RAID Characteristics of a LUN
■ Changing Attributes of a LUN
Each task is discussed in the following paragraphs.
Adding Drives to an Array
To add additional physical drives to an array:
Note: Because this command affects the entire array, all LUNs made from the array are
also affected.
Basic Command
EXPAND UNIT
Example Command
CLI> EXPAND UNIT 4 DISK204-DISK207
Command Options
4—one of the LUN within the target array.
Note: Any LUN in the array can be entered to identify the array; the space is added to
the array and not the LUN.
DISK204-DISK207—the physical disks to add to the array. Disks are identified
by box number and bay number. In this example,
DISK204-DISK207 identifies
disks 4 through 7 in box number 2.
Example CLI Response
The actual new array capacity will be 3000MB.
The array with Unit 4 is being expanded.
Use “show unit 4” to monitor progress.
