IBM 86624RY Maintenance Manual - Page 324

Note Refer to the HMM (Hardware Maintenance Manual) specific to the system comprising the SCSI channel for jumper details. e. Check for proper cabling configuration in systems that use DASD status cables. Reconnect all cables removed in step 1 above. f. Disconnect one drive at a time attached to the channel identified in step 2a, then reboot to determine which drive is causing the error. g. Replace SCSI cable. h. Replace SCSI backplane. EF10 (Default ISPR) 1. No ISPR error present. 2. Controller is probably functioning properly. Do not replace system board unless you have run the controller's diagnostics and you get an error message. If you do not get an error message, assume it is functioning properly. 3. Refer to "ServeRAID Startup Messages" on page 318. Note the resulting BCS and or ECS Error codes, and see the FRU actions respective to those codes. (EF10 is a default code for ISPR indicating that there is no ISPR error present.) EFFE (Firmware code corrupted or download jumpers are in place.) 1. Verify download jumpers are in their default locations. See "System board jumpers" on page 280 for jumper locations. 2. If download jumpers are not in place and error still persists, then flash the controller firmware with the jumpers in place; then remove the jumpers. 3. If error persists after step 2, replace the controller or the system board with integrated controller. FFFF or other code not listed 1. Isolate between SCSI subsystem and controller by disconnecting all SCSI cables attached to the suspect controller and reboot. If ISPR code is EF10 after disconnecting cables, follow the steps below until the error is eliminated: a. Identify which channel is causing the error by reconnecting cables one at a time and rebooting until the error returns. b. Check termination of identified channel in step 1a. 316 Netfinity Server HMM
