Troubleshooting Your Enclosure
NOTE:
In a split-mode configuration, these conditions apply to the server that is directly attached to the affected
EMM. In a unified-mode configuration, these conditions apply when communication is lost to any enclosure in the
daisy chain.
Problem
• The PERC 5/E Adapter Ctrl-R utility reports:
– Physical disks and virtual disks as Offline, Degraded, Failed, or Foreign
• Server Administrator Storage Management reports:
– Lost Communication alert(s) to the Server Administrator Alert Log
– The enclosure, physical disks, and virtual disks as Offline, Degraded, Failed, or Foreign
NOTE:
These messages are logged as a result of a loss of communication and do not indicate actual hardware
component failures.
Action
1
Power down the server.
2
Verify that all storage subsystem cabling between the PERC5/E Adapter and all attached enclosures,
including daisy-chained enclosures, is properly connected and secured.
3
Ensure that all the enclosures are powered up.
4
Power up the server.
The PERC 5/E Adapter should recover without any additional user intervention or warning/error
messages.

– Foreign Configuration
– Failed Virtual Disks
Action
• Foreign Configuration
1
Enter the Ctrl-R utility
2
Import the foreign configuration (right click "controller" for a drop-down menu with this selection).
