IBM xSeries 345 Type 8670: Installation Guide
Suggested action
Verify that:
v The cables for all external SCSI options are connected correctly.
v The last option in each SCSI chain, or the end of the SCSI cable, is terminated
correctly.
v Any external SCSI option is turned on. You must turn on an external SCSI option
before turning on the server.
For more information, see your SCSI expansion enclosure documentation.
Call for service.
1. Remove the first drive not recognized and try the hard disk drive diagnostic test
again.
2. If the remaining drives are recognized, replace the drive you removed with a
new one.
1. Remove the hard disk drive being tested when the server stopped responding
and try the diagnostic test again.
2. If the hard disk drive diagnostic test runs successfully, replace the drive you
removed with a new one.
Verify that:
v All cables and cords are connected securely to the rear of the server and
attached options.
v When the server is turned on, air is flowing from the rear of the server at the fan
grill. If there is no airflow, the fan is not working. This causes the server to
overheat and shut down.
v Ensure that the SCSI bus and devices are configured correctly and that the last
external device in each SCSI chain is terminated correctly.
If you have verified these items and the problem remains, call for service.
v Make sure that the keyboard cable is properly connected to the server.
v Make sure that the server and the monitor are turned on.
v Try using another keyboard.
If the problem remains, call for service.
v Verify that the mouse or pointing-device cable is securely connected and the
device drivers are installed correctly.
v Try using another mouse or pointing device.
If the problem remains, call for service.
