Chaparral K5312/K7313, G5312/G7313 manual Adding a Dedicated Spare, To add a dedicated spare

G- and K-Series User’s Guide

While using a dedicated spare is the most secure way to provide spares for your arrays, it is also expensive to keep an idle drive assigned to each array. An alternative method is to assign one or more idle drives to the spare pool. See Managing the Spare Pool on page 6-5.

Adding a Dedicated Spare

You assign dedicated spare drives to a specific array. If a member drive in the array fails, the controller uses a dedicated spare drive to automatically reconstruct the array. You can add dedicated spare drives to Mirrored (RAID 1 and RAID 10) and Parity (RAID 3, RAID 4, RAID 5, and RAID 50) arrays when you create the array or afterward. You can assign up to four dedicated spare drives to an array. For more information about assigning spares when you create an array, see Creating Arrays on page 4-1.

Note: A spare cannot be added that does not have enough capacity to replace the smallest member in the array.

To add a dedicated spare:

1From the System Menu, select Array Menu and press Enter. The Select Array screen displays with a list of existing arrays.

2Select the array you want and press Enter. The Array Menu screen displays.

3Select Add Spare and press Enter.

The list of drives screen displays listing the available drives.

Note: If a drive was a member of an array and was removed from the array, you cannot use it as a spare until you clear the drive’s metadata. For more information, see Clearing Metadata from a Drive on page 8-4.

4Select the drive you want to add as a spare and press Enter. The system confirms the change.

5Select Yes and press Enter.
