•If the array contains a RAID 1+0 logical drive, you can remove only an even number of drives.

•If the array contains a compound RAID (RAID 50 or RAID 60) logical drive, you can remove drives only in multiples of the number of parity groups. For example, an array with 10 physical drives and a RAID 50 logical drive can be shrunk by removing two or four drives only.

Syntax:

<target> remove drives=[#:]#:#-[#:]#:#

where <target> is an array, and the specified physical drives are being removed to shrink the array.

For example, in an existing array (array a), six drives (1e:1:4-1e:1:9) are in use. With all criteria met, you

can shrink the array to four drives by removing the last two drives with the command: <array a> remove drives=1e:1:8-1e:1:9

Example commands:

=> array a remove drives=1e:1:12-1e:1:14 => array b remove drives=1c:1:6-1c:1:7

Moving an array

Some controllers may not support this option or may require a license key to enable this feature.

You can move an array by designating different physical drives for the array. To move the array, each of the physical drives where the array will reside must meet the following criteria:

•It must be an unassigned drive.

•It must be of the same type as the physical drives currently in the source array (for example, SATA or SAS).

•The destination drives must have sufficient capacity to hold all the logical drives present in the source array.

Like array creation and expansion, the useable space in all drives is reduced to the size of the smallest physical drive in the destination disk set.

Moving an array automatically removes any previously assigned spare drives. If spares are assigned to the existing array, they must be designated for the array when it is moved.

Syntax:

<target> modify drives=[#:]#:#-[#:]#:# spares=[#:]#:#-[#:]#:#

where <target> is an array, and the specified physical drives are the new destination for the array.

For example, in an existing array, three 72-GB SAS drives (1e:1:4-1e:1:6) are the source. Another drive of the same size is the spare (1e:1:9). With all criteria met, you can move the array to three different 72-GB SAS drives by specifying the new destination drives in the command (1e:1:12-1e:1:14). To maintain the same spare drive, be sure to designate the spare drive for the moved array.

Example commands:

=> array a modify drives=1e:1:12-1e:1:14 spares=1e:1:9 => array b modify drives=1c:1:6-1c:1:7

Replacing an array

Some controllers may not support this option or may require a license key to enable this feature.

You can replace an array by designating different physical drives for the array. To replace the array, each of the physical drives where the array will reside must meet the following criteria:
