You can manually assign or unassign specific disk drives as hot-spares, or you can select the number of hot-spares you want and let the management software assign or unassign the disk drives automatically.
To manually assign or unassign a hot-spare:
The Array Summary page is displayed.
The Volume Summary page is displayed.
The Disk Summary page is displayed.
When the management software assigns the hot-spares, it balances the request for spares across all trays within the array and ensures that the hot-spare drive is of the same type as the other disks in the same tray. It also verifies that the disk drives are unassigned, enabled, and in the optimal state.
To enable the management software to assign or unassign a hot-spare:
The Array Summary page is displayed.
The Volume Summary page is displayed.
The General Setup page is displayed.
The management software assigns or unassigns the specified number of hot-spares. The management software balances the selection among trays within the array.
