SCSI error messages Note: See Chapter 8, "Parts listing, Type 8870," on page 249 to determine which components are replaceable by the customer, and which components should be replaced by an IBM field service technician. Error message FRU/action 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 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, verify that 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. ServeRAID (ISPR) error procedures Use the ISPR error procedures to help you solve ServeRAID problems. A complete list of error codes is listed at "ServeRAID error codes" on page 244. Note: Where the ISPR Error Procedures refer to a hard disk drive backplane, see the chapter of this publication that concerns service replaceable units. EF10 (Default ISPR) 1. No ISPR error present. 9ZXX through BZXX (SCSI bus error caused either by cables, termination, defective drives, etc.) 1. Isolate between SCSI subsystem and controller by disconnecting all hard disk drive cables from suspect card, and reboot. CAUTION: Do not press F5. Doing so changes the server's configuration. If an ISPR error is still present, perform the following actions until the error is no longer present: a. Reseat the controller b. Replace the controller Notes: a. SCSI channel cable details, if any, appear elsewhere in this publication. b. The adapter/controller detects a configuration change. Do not choose Save Changes. Instead, press F10 to bypass any options to this effect. 2. If ISPR error is EF10 after disconnecting cables: a. Identify which channel is causing the error by the second digit (Z) of the original ISPR code as indicated in the following table: 242 xSeries 445 Type 8870: Hardware Maintenance Manual and Troubleshooting Guide
