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
2. If ISPR error is EF10 after disconnecting cables:

xSeries 206 Type 8482 and 8487: Hardware Maintenance Manual and Troubleshooting Guide
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 publication.
b. The adapter/controller detects a configuration change. Do not select Save
Changes. Instead, press F10 to bypass any options to this effect.
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 and ServeRAID-6i
controllers have no channels. The ServeRAID-5i and ServeRAID-6i
use the channel connectors of the onboard integrated SCSI
controller.

of the error by verifying that the error presents itself only when the offending
channel is reconnected.
