Adding a Dedicated Spare

This function allows the user to add dedicated spares to a specific array. If a member drive

in the array fails, the controller will use a dedicated spare drive to automatically reconstruct

the array. The user can add dedicated spares to Mirrored (RAID 1 and RAID 10) and parity

(RAID 3, RAID 4, RAID 5, and RAID 50) arrays at anytime. Up to four (4) dedicated spare drives

can be added to an array (refer to section "Creating Arrays" for further information).

NOTES:

A spare cannot be added unless it has enough capacity to replace the

smallest member in the array.
If a drive was a member of an array and was removed from the array, it

cannot be used as a spare until all the metadata is cleared from the drive

(refer to section "Clearing Metadata from a Drive" for further information).

To add a dedicated spare:

Select Array Menu from the System Menu and press Enter.
The Select Array screen will display, along with a list of existing arrays (Figure 19).

Select the desired array and press Enter.
The Array Menu should now display (Figure 20).

Select Add Spare and press Enter.
The List of Available Drives screen should now display.

Select the drive to add as a spare and press Enter.
The system will confirm your request to add the spare.

Select Yes and press Enter.
