Property Denition
The foreign conguration may be in degraded or failed state due to any of the following
reasons:
• Missing physical disk — One of the physical disk(s) in the potential virtual disk is missing or
not available.
• Missing span — One or more spans of a hybrid virtual disk is missing.
• Stale physical disks — One or more physical disks in the conguration may contain out-of-
date data relating to other disks of that virtual disk. Hence, the data integrity of the
imported virtual disk is not intact.
• Unsupported conguration of the virtual disk — The virtual disk has an unsupported RAID
level.
• Import and Export — The virtual disks available for import exceed the number of virtual
disks available for export.
• Incompatible physical disks — Conguration on the physical disks is not recognized by the
RAID rmware.
• Orphan drive — A physical disk in the foreign conguration has conguration information
that matches another physical disk that is already a part of an array (either a foreign or a
native array).
NOTE: For other applicable physical disk tasks and properties, see Physical Disk Or
Physical Device Properties and Physical Disk Or Physical Device Tasks.
Layout Displays the RAID level of the foreign conguration.
Remarks Provides information about the foreign virtual disk. If the virtual disk cannot be imported, the
reason for failure is displayed.
• Exceeded maximum — The number of virtual disks selected for import has exceeded the
maximum number of supported disks.
• Missing physical disk or Missing span — One or more physical disk(s) or span(s) in the
virtual disk to be imported is missing.
• Unsupported — The selected RAID level is not supported on this controller.
• Orphan drive — The physical disk has been replaced and is no longer a part of the RAID
volume. The conguration should be cleared.
• Stale physical disk — The physical disk to be imported in the virtual disk has outdated data.
• Partially foreign — The virtual disk is part of an already existing conguration. Some
physical disks in this virtual disk are foreign.
Dedicated Hot Spare Displays whether the foreign disk is a dedicated hot spare.
Based on the properties information, you can decide whether you want to import, recover, or clear the foreign conguration.
To Locate Foreign Conguration Operations Task In Storage Management
For SAS controllers with rmware version 6.1:
1. In the Server Administrator window, under the system tree, expand Storage to display the controller objects.
2. Select a controller object.
3. Click Information/Conguration on the controller Properties page.
4. Select Foreign Conguration Operations from the Controller Tasks drop-down menu.
5. Click Execute.
Importing Foreign Congurations
Some controllers enable you to import a foreign conguration so that virtual disks are not lost after moving the physical disks.
You can import a foreign conguration only if it contains a virtual disk that is either in a Ready or Degraded state. In other words, all
of the virtual disk data must be present, but if the virtual disk is using a redundant RAID level, the additional redundant data is not
required.
