9Zxx thru BZxx (SCSI bus error caused by cables, termination, defective drives, or similar problem) 1. Isolate between SCSI subsystem and controller by disconnecting all SCSI cables from suspect card, and restart. Attention: Do not press F5. Doing so changes the server 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 document. b. The adapter/controller detects a configuration change. Do not select 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. Note: ServeRAID-4H controllers have 4 channels; ServeRAID-4L and -4Lx controllers have only one channel; and ServeRAID-4M and -4Mx controllers have 2 channels. ServeRAID-5i controllers have no channels. The ServeRAID-5i uses the channel connectors of the onboard integrated SCSI controller. Table 2.

Confirm that the channels identified from the error in step 2a 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 document. Chapter 7. Symptom-to-FRU index 95
