If you insert a physical disk that was previously a member of a virtual disk in the
system, and that disk’s previous location has been taken by a replacement disk
through a rebuild, you must manually remove the foreign configuration flag of the
newly inserted disk.

Previous configuration cleared or missing error message

Error Message: Previous configuration(s) cleared or missing. Importing
configuration created on XX/XX XX.XX. Press any key to
continue, or ’C’ to load the configuration utility.
Probable
Cause:
The message indicates that the controller and physical disks have different
configurations.
Corrective
Action:
You can use the BIOS Configuration Utility (<Ctrl> <R>) to clear the foreign
configuration.

Invalid SAS topology detected error message

Error Message: Invalid SAS topology detected. Please check your cable
configurations, repair the problem, and restart your system.
Probable
Cause:
The SAS cables for your system are improperly connected.
Corrective
Action:
Check the cable connections and fix problems if any. Restart the system.

Configured disks removed or not accessible error message

Error Message: Some configured disks have been removed from your system or are
no longer accessible. Check your cables and ensure all disks
are present. Press any key or ’C’ to continue.
Probable
Cause:
The message indicates that some configured disks were removed. If the disks were
not removed, they are no longer accessible. The SAS cables for your system might
be improperly connected.
Corrective
Action:
Check the cable connections and fix issues if any. Restart the system. If there are
no cable problems, press any key or <C> to continue.
Degraded state of virtual disks
A redundant virtual disk is in a degraded state when one or more physical disks have failed or are
inaccessible. For example, if a RAID 1 virtual disk consists of two physical disks and one of them fails or
become inaccessible, the virtual disk become degraded.
To recover a virtual disk from a degraded state, you must replace the failed physical disk and rebuild it.
Once the rebuilding process is complete, the virtual disk state changes from degraded to optimal. For
information on rebuilding the disk, see Performing A Manual Rebuild Of An Individual Physical Disk.
