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 powered-on before you power-on the server. 2. 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. The last device in each SCSI chain is terminated correctly. 5. The SCSI devices are configured correctly. Temperature error messages Message Action DASD Over Temperature (level-critical; 1. Ensure system is being properly cooled; see "System reliability Direct Access Storage Device bay ″X″ was considerations" on page 41. over temperature) DASD Over recommended Temperature (sensor X) (level-warning; DASD bay ″X″ had over temperature condition) 1. Ensure system is being properly cooled; see "System reliability considerations" on page 41. DASD under recommended temperature (sensor X) (level-warning; direct access storage device bay ″X″ had under temperature condition) 1. 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) 1. Ensure system is being properly cooled; see "System reliability considerations" on page 41. 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 41. 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 41. 2. Replace system board System board is under recommended temperature (level-warning; system board is under recommended temperature) 1. Ambient temperature must be within normal operating specifications; see "Features and specifications" on page 3. System over temperature for CPU ″X″ (level-warning; CPU ″X″ reporting over temperature condition) 1. Ensure system is being properly cooled; see "System reliability considerations" on page 41. System under recommended CPU ″X″ temperature (level-warning; system reporting under temperature condition for CPU ″X″) 1.
