Cause
An error occurred on PCI bus B. An
adapter in PCI slot 2, 3, 4 or the
system board caused the error.
An error occurred on PCI bus C. An
adapter in PCI slot 5 or 6 or the system
board caused the error.
A hot-swap hard disk drive has failed
on SCSI channel B.
A memory error occurred.
Action
1. Check the error log for additional
information.
2. If you cannot correct the problem
from the information in the error
log, try to determine the failing
adapter by removing one adapter
at a time from PCI bus B (PCI
slots 2, 3, and 4) and restarting
the server after each adapter is
removed.
If the problem persists, have the
system serviced.
