6Select the drives you want to use for the array and press Enter.

You select a drive by highlighting it and pressing Enter. Each selected drive turns gray in the drive list. After you press Enter for the number of drives you entered previously, the system automatically goes to the next screen. To skip a drive, use the ↑ or ↓ key.

You may want to select drives from different disk channels (I/O modules), which keeps the array online even if one channel becomes unavailable.

If the array is mirrored, RAID 3, RAID 4, RAID 5, or RAID 50 and you have one or more drives left, the Number of Spares screen displays.

7If the Number of Spares screen displays, enter the number of spares you want to add and press Enter.

This creates dedicated spares that can only be used by this array. A dedicated spare drive will not be available for any other use.

If you do not want a dedicated spare, enter 0. The Select Drives screen displays.

8If the Select Drives screen displays, select the drive you want to use as a dedicated spare and press Enter.

Only available drives, that is, drives that are not members of an array and are not assigned as a dedicated or pool spares, display. You can delete a dedicated spare from the array at any time. For more information, see E.1.2, ”Deleting a Dedicated Spare”, on page 168.
