POST (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 133.
Note: Where the ISPR Error Procedures refer to a SCSI backplane, see the
chapter of this publication that concerns service replaceable units.
EF10 (Default ISPR)
1. No ISPR error present.
9 ZXX through B ZXX (SCSI bus error caused either by cables, termination,
defective drives, etc.)
1. Isolate between SCSI subsystem and controller by disconnecting all SCSI
cables from suspect card, and reboot.
CAUTION:
Do not press F5. Doing so changes the server’s 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 choose 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 are not
supported on this server.
