Foreign Configuration properties The following table describes the properties that are displayed on the PERC BIOS Configuration Utility Foreign Configuration screen for the Foreign Disks and Global Hot Spares. Table 20. Memory channels Property Status Definition These icons represent the severity or health of the storage component. Name State Layout Remarks • -Normal/OK • -Warning/Non-critical • -Critical/Failure/Error Displays the name of the foreign configuration and is available as a link. This link enables you to access the physical disks that constitute the foreign disk. Displays the current state of the foreign configuration. Possible values are: • Ready - The foreign disk can be imported and functions normally after import. • Degraded - The foreign disk is in degraded state and rebuilds after import. • Failed - The foreign disk has encountered a failure and is no longer functioning. You cannot import the foreign configuration. The foreign configuration 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 • Stale physical disks - One or more physical disks in the configuration may contain out-of-date data relating to other disks of that virtual disk.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 configuration 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 - Configuration on the physical disks is not recognized by the RAID firmware. • Orphan drive - A physical disk in the foreign configuration has configuration information that matches another physical disk that is already a part of an array (either a foreign or a native array). Displays the RAID level of the foreign configuration. 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 configuration 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 configuration. Some physical disks in this virtual disk are foreign. Troubleshooting hardware issues 77

Foreign Configuration properties
The following table describes the properties that are displayed on the
PERC BIOS Configuration Utility Foreign Configuration
screen
for the Foreign Disks and Global Hot Spares.
Table 20. Memory channels
Property
Definition
Status
These icons represent the severity or health of the storage component.
•
—
Normal/OK
•
—
Warning/Non-critical
•
—
Critical/Failure/Error
Name
Displays the name of the foreign configuration and is available as a link. This
link enables you to access the physical disks that constitute the foreign
disk.
State
Displays the current state of the foreign configuration. Possible values are:
•
Ready
— The foreign disk can be imported and functions normally
after import.
•
Degraded
— The foreign disk is in degraded state and rebuilds after
import.
•
Failed
— The foreign disk has encountered a failure and is no longer
functioning. You cannot import the foreign configuration.
The foreign configuration 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 configuration
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 configuration 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 — Configuration on the physical disks is not
recognized by the RAID firmware.
•
Orphan drive — A physical disk in the foreign configuration has
configuration information that matches another physical disk that is
already a part of an array (either a foreign or a native array).
Layout
Displays the RAID level of the foreign configuration.
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 configuration 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
configuration. Some physical disks in this virtual disk are foreign.
