PCI B An error occurred on PCI bus B. An adapter
in PCI slot 3, 4, or 5 caused the error, or the
system board caused the error.
VRM One of the VRMs on the system board has
failed.
DASD1 SCSI channel A has failed. (This is the SCSI
channel for the hot-swap hard disk drives.)
DASD2 SCSI channel B has failed. (This is the
channel for optional SCSI devices installed
in the non-hot-swap bays.)

Cause Action
1. Check the error log for additional
information.
2. If you cannot isolate the failing adapter
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 3, 4, and 5) and
restarting the server after each adapter is
removed.
If the problem persists, have the system
serviced.
Check the VRM failure LEDs on the system
board.
• If the VRM1 Failure LED is on, have
the system serviced.
• If the VRM2 Failure LED is on:
1. Turn off the server, reseat the VRM,
and restart the server.
2. If the problem persists, replace the
VRM.
If the problem still persists, have the system
serviced.
1. If an amber LED on a hot-swap hard
disk drive is on, replace the hard disk
drive
2. Run the diagnostics programs. Replace
any identified failing device.
3. If the error log indicates a temperature
problem and the fans are working
correctly, have the system serviced.
If the problem persists, have the system
serviced.
1. Run the diagnostics programs.
2. If no failing device is identified by the
diagnostics programs, try to determine
the failing device by removing one
device at a time from the channel and
restarting the server after each device is
removed.
If the problem persists, have the system
serviced.
