Table 6. SCSI identifier (continued) SCSI Channel Code (z) D E F Descriptions Channel 1, 3, & 4 Channel 2, 3, & 4 Channel 1, 2, 3, & 4 b. Confirm that the channel(s) identified from the error in step 2a on page 134 is (are) the cause of the error by verifying that the error presents itself only when the offending channel is reconnected. c. Check termination of identified channel. Note: SCSI channel termination details, if any, appear elsewhere in this publication. d. Check for proper backplane jumper configuration. Note: SCSI channel jumper details, if any, appear elsewhere in this publication. e. Check for proper cabling configuration in systems that use DASD status cables. Reconnect all cables removed in step 1 on page 134. f. Disconnect one drive at a time attached to the channel identified in step 2a on page 134; then, reboot to determine which drive is causing the error. g. Replace SCSI cable. h. Replace SCSI backplane. FFFF or other code not listed 1. Place download jumpers on the controller and try to flash the firmware code to the card. 2. Isolate between SCSI subsystem and controller by disconnecting all SCSI cables attached to the suspect card, and reboot. CAUTION: Do not press F5. Doing so will change the server's configuration. 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 2a. Note: SCSI channel termination details, if any, appear elsewhere in this publication. c. Disconnect one drive at a time attached to channel identified in step 2a and reboot each time to determine which drive is causing the problem. d. Replace SCSI cable attached to channel identified in step 2a. e. Replace backplane attached to channel identified in step 2a. 3. If original ISPR code is still present after disconnecting all SCSI cables and rebooting, perform the following actions until the error is no longer present: v Reseat the controller v Replace the controller Chapter 6.
