Error Code/Symptom Bxxx (SCSI bus interface error) SCSI error codes Action 1. Refer to "ServeRAID POST (ISPR) error procedures" on page 232. 2. SCSI cable 3. SCSI backplane 4. Hard drive 5. ServeRAID 3HB Adapter/Controller Error Code All SCSI Errors One or more of the following might be causing the problem: • A failing SCSI device (adapter, drive, controller) • An improper SCSI configuration or SCSI termination jumper setting • Duplicate SCSI IDs in the same SCSI chain • A missing or improperly installed SCSI terminator • A defective SCSI terminator • An improperly installed cable • 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.
