SCSI error codes

Error code
All SCSI Errors One or more of the
following might be causing the problem:
v A failing SCSI device
(adapter, drive, controller)
v An improper SCSI configuration or SCSI
termination jumper setting
v Duplicate SCSI IDs in the same SCSI
chain
v A missing or improperly installed SCSI
terminator
v A defective SCSI terminator
v An improperly installed cable
v A defective cable

Temperature error messages

Note: See "System" on page 112 to determine which components should be replaced by a field service technician.
Message
DASD Over Temperature
(level-critical; direct access storage device
bay x was over temperature)
DASD Over recommended Temperature
(sensor x)
(level-warning; DASD bay x had over
temperature condition)
DASD under recommended temperature
(sensor x) (level-warning; direct access
storage device bay x had under
temperature condition)
If ISPR code is EF10 after disconnecting cables, follow the steps below until the
error is eliminated:
a. Identify which channel is causing the error by reconnecting cables one at a
time and rebooting until the error returns.
b. Check termination of identified channel in step 2a.
Note: SCSI channel termination details, if any, appear elsewhere in this
publication.
c. Disconnect one drive at a time attached to channel identified in step 2a and
reboot each time to determine which drive is causing the problem.
d. Replace SCSI cable attached to channel identified in step 2a.
e. Replace backplane attached to channel identified in step 2a.
rebooting, perform the following actions until the error is no longer present:
v Reseat the controller
v Replace the controller
FRU/action
1. External SCSI devices must be turned on before you turn on
the server.
2. Make sure that the cables for all external SCSI devices are
connected correctly.
3. If you have attached an external SCSI device to the server, make
sure the external SCSI termination is set to automatic.
4. Make sure that the last device in each SCSI chain is terminated
correctly.
5. Make sure that the SCSI devices are configured correctly.
Action
v Ensure that the system is being properly cooled; see "System
reliability considerations" on page 37.
v Ensure that the system is being properly cooled; see "System
reliability considerations" on page 37.
v Ambient temperature must be within normal operating
specifications; see "Features and specifications" on page 2.
