Service processor error codes
Service processor error codes in the POST error log will appear in hexadecimal
form (generally beginning with A2, A3, A4, A5, A6, A7, AD, AE, or E1). These error
codes will appear in text format when viewed from the System Error Log through
the diagnostic programs. To determine a possible error condition for the service
processor, view the System Error Log from the diagnostic programs (see "Viewing
error logs from diagnostic programs" on page 28).

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
