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

—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.
