Figure 4-21 Disk Group Discovery
Orphan Disks
An Orphan Disk is a disk that contains information about membership in a Disk Group that has
either been removed from the Disk Group or is designated as an Orphan because there are not
enough of the Disk Group members available in the system to build the Disk Group.
This condition can occur when a disk has been improperly removed from the system and a hot
spare disk has replaced the Orphan Disk in the Disk Group. Since the Disk Group is rebuilt
using the Spare Disk, the Orphan cannot be used in the Disk Group.
This condition may also occur when some of the disks from a Disk Group are moved to a new
chassis. Without enough Disk Group members present to reassemble the Disk Group, the
system labels the disks as orphans. In this case, you can either locate and add the missing Disk
Group members or convert the Orphan Disks to Spare Disks and rebuild the Disk Group from
available Spare Disks. In this case all information on the disks will be lost.
Converting an Orphan Disk to a Spare will remove all data from the disks. Only those disks that
are in an Orphan state may be selected to be converted. Click on the Convert button in the
Orphan Disk to Spare disk page, shown in, to convert the disks.
