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
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
2. If ISPR error is EF10 after disconnecting cables:
