Location Codes Displayed By Diagnostics

When the AIX diagnostics detect a failure in the 2102 Fibre Channel RAID
subsystem, the failure information includes a location code used to physically
identify the failing component within the subsystem. The following describes how to
interpret the reported location codes:
v Translating location codes for a disk drive failure:
v Translating location codes for other subsystem component failures (other
Disk drive failures will be reported in the following format:
653153: Drive failed by user via Mode Select.
Refer to the 2102 Model F10 Service Guide for more information.
100% 17.357GB
Location code CH5 ID8 D0 indicates that the failing disk drive is on channel 5,
SCSI ID 8 and is assigned to dac0.
than disk drives):
Subsystem component failures, other than disk drives, will be reported in the
following format:
555203: Enclosure status reports a non-critical fan failure.
Refer to the 2102 Model F10 Service Guide for more information.
100% E6 D0 Fan module
Location code E6 D0 means the fan is in the enclosure with EID=6 and assigned
to dac0.
Description
Enclosure status reports that the subsystem is operating at
higher than normal temperature.
Action:
v For Controller Module fan failures, read the procedure
"Determining Which Fan Failed" on page 102 and replace
FRUs as instructed. If the problem persists, replace the
controller backpanel.
v For Drive Drawer fan failures, replace the Device Drawer
Fan. If the problem persists, replace the ESM. If the
problem still persists, replace the device drawer
midplane/chassis.
