Dell POWERVAULT MD3620I - Manual (Page 131)

Configuration: Disk Groups and Virtual Disks 131
• The availability of enclosure loss protection for a disk group depends on
the location of the physical disks that comprise the disk group. To make
sure that enclosure loss protection is not affected, you must replace a failed
physical disk to initiate the copyback process. See "Enclosure Loss
Protection" on page 134.
CAUTION: If a hot spare physical disk does not have Optimal status, follow the
Recovery Guru procedures to correct the problem before you try to unassign the
physical disk. You cannot assign a hot spare physical disk if it is in use (taking
over for a failed physical disk).
To assign or unassign hot spare physical disks:
1 In the AMW, select the Physical tab.
2 Select one or more physical disks.
3 Perform one of these actions:
• Select Physical disk Hot Spare Coverage.
• Right-click the physical disk and select Hot Spare Coverage from the
pop-up menu.
The Hot Spare Physical Disk Options window is displayed.
4 Select the appropriate option, you can select:
• View/change current hot spare coverage—to review hot spare coverage
and to assign or unassign hot spare physical disks, if necessary. See
step 5.
• Automatically assign physical disks— to create hot spare physical disks
automatically for the best hot spare coverage using available physical
disks.
• Manually assign individual physical disks—to create hot spare physical
disks out of the selected physical disks on the Physical tab.
• Manually unassign individual physical disks—to unassign the selected
hot spare physical disks on the Physical tab. See step 12.
5 To assign hot spares, in the Hot Spare Coverage window, select a disk
group in the Hot spare coverage area.
