Troubleshooting Your Enclosure 45
• Failed Virtual Disks
NOTE: This warning message appears if one or more virtual disk(s) are spanned across two or more
enclosures or if an enclosure in split mode is shared by one server.
1 During POST, press <Ctrl><R> to enter the Ctrl-R utility.
2 Find the virtual disk(s) marked as Failed and record all settings from the Properties screen, including
RAID level, physical disk members, physical disk order (sequence), virtual disk size, and stripe
(element) size.
3 Delete the failed virtual disk.
4 Clear the remaining foreign configuration.
5 Re-create the original virtual disk using the original set of disk drives, and the identical parameters
recorded in step 2. This re-establishes the configuration information.
NOTE: Do not initialize the new virtual disks.
6 Exit the Ctrl-R utility and boot to the operating system.
For more information on the Ctrl-R utility, see the Dell PERC5/E Adapter User’s Guide.
Troubleshooting External Connections
Loose or improperly connected cables and bent pins are the most likely source of problems. Ensure that all
external cables are securely attached to the external connectors on your system and that none of the
connectors are damaged. See "Back-Panel Indicators and Features" for the back-panel connectors on your
enclosure.
