Service processor error codes When viewed from POST, Remote Supervisor Adapter error codes will appear in hexadecimal form (generally beginning with A2, A3, A4, A5, A6, A7, AD, AE, or E1). However, when viewed from the System Error Log, the messages will appear as text. To determine a possible error condition for the service processor, see the System Error Log (see "Viewing error logs from diagnostic programs" on page 22). 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 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. Temperature error messages Note: See "System replaceable units" on page 122 to determine which components should be replaced by a field service technician. Message Action DASD Over Temperature (level-critical; direct access storage device bay x was over temperature) Ensure that the system is being properly cooled; see "System reliability considerations" on page 33 DASD Over recommended Temperature (sensor x) (level-warning; DASD bay x had over temperature condition) Ensure that the system is being properly cooled; see "System reliability considerations" on page 33 DASD under recommended temperature (sensor x) (level-warning; direct access storage device bay x had under temperature condition) Ambient temperature must be within normal operating specifications; see "Features and specifications" on page 3 DASD Over Temperature (level-critical; sensor for DASD1 reported temperature over recommended range) Ensure that the system is being properly cooled; see "System reliability considerations" on page 33 Power supply x Temperature Fault (level-critical; power supply x had over temperature condition) 1. Ensure system is being properly cooled; see "System reliability considerations" on page 33 2. Replace power supply x System board is over recommended temperature (level-warning; system board is over recommended temperature) 1. Ensure system is being properly cooled; see "System reliability considerations" on page 33 2. Replace the system board. 114 IBM xSeries 225 Types 8649: Hardware Maintenance Manual and Troubleshooting Guide
