POST (ISPR) Error Procedures



POST (ISPR) Error Procedures

The ISPR Error Procedures list errors, symptoms, and the possible causes.
The most probable cause is listed first. Use these procedures to help you solve ServeRAID problems when servicing the computer.

Note: Where the ISPR Error Procedures refer to a SCSI backplane, see the Hardware Maintenance Manual for the system you are servicing.

See ServeRAID Diagnostics Test Program for a description of the diagnostic programs that come with the server.

EF10 (Default ISPR)
1. No ISPR Error Present.
1XXX (Microcode Checksum Error)
1. Replace the PC ServeRAID 3L Adapter/Controller.

2XXX thru 8XXX (Code DRAM Error)
  1.  Install download jumpers. For jumper locations, see Locations (IBM PC ServeRAID 3L Ultra SCSI Adapter).

  2.  Flash the adapter/controller with the latest IBM PC ServeRAID BIOS/Firmware from the IBM Website.
  3.  Remove the jumpers.
  4.  If the error persists, replace PC ServeRAID 3L Adapter/Controller.


9XXX thru BXXX (SCSI bus error caused either by defective drives, termination, etc.)

  1.  Isolate between SCSI subsystem and adapter by disconnecting all SCSI cables from suspect card, and reboot.

    Caution: Do not press F5. Doing so changes the customer's configuration.

     If an ISPR error is still present, perform the following actions until the error is no longer present:

    1.  Reseat the adapter
    2.  Replace the adapter

      Notes:

      1.  Refer to the HMM (Hardware Maintenance Manual) specific to the system  comprising the SCSI channel for SCSI cable details.
      2.  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:

    1.  Identify which channel is causing the error by the second digit of the original ISPR code:

      •  ISPR = B1xx = Channel 1
      •  ISPR = B2xx = Channel 2
      •  ISPR = B3xx = Channel 1 and 2
      •  ISPR = B4xx = Channel 3
      •  ISPR = B5xx = Channel 1 and 3
      •  ISPR = B6xx = Channel 2 and 3
      •  ISPR = B7xx = Channel 1, 2 and 3
      •  ISPR = BFxx = Channel not identified

    2.  Confirm that the channel(s) identified from the error in step 2a is(are) the cause  of the error by verifying that the error presents itself ONLY when the offending channel is reconnected.

    3.  Check termination of identified channel.

      Note: Refer to the HMM (Hardware Maintenance Manual) specific to the system comprising  the SCSI channel for termination details.

    4.  Check for proper backplane jumper configuration.

      Note: Refer to the HMM (Hardware Maintenance Manual) specific to the system  comprising the SCSI channel for jumper details.

    5.  Check for proper cabling configuration in systems that use DASD status cables.
       Reconnect all cables removed in step 1 above.
    6.  Disconnect one drive at a time attached to the channel identified in step 2a, then  reboot to determine which drive is causing the error.
    7.  Replace SCSI cable.
    8.  Replace SCSI backplane.


EF10 (Default ISPR)

  1.  Adapter/controller is probably functioning properly. Do not replace  adapter/system board unless you have run the adapter's diagnostics and you get  an error message. If you do not get an error message, assume it is functioning properly.
  2.  Refer to Drive Configuration Conflict Resolution.
     Note the resulting BCS and or ECS Error codes, and see the FRU actions respective to those  codes. (EF10 is a default code for ISPR indicating that there is no ISPR error present.)


EFFE (Firmware code corrupted or download jumpers are in place.)

  1.  Verify download jumpers are in their default locations.  See Locations (IBM PC ServeRAID 3L Ultra SCSI Adapter)  for jumper locations.

  2.  If download jumpers are not in place and error persists, then flash the  adapter/controller firmware with the jumpers in place, then remove the download jumpers.

  3.  If error persists after step 2, replace the adapter or the system board with integrated controller.


FFFF or other code not listed

  1.  Isolate between SCSI subsystem and adapter/controller by disconnecting  all SCSI cables attached to the suspect adapter and reboot.

    Caution: Do not press F5. Doing so will change the customer's configuration.

     If ISPR code is EF10 after disconnecting cables, follow the steps below until the error is eliminated:

    1.  Identify which channel is causing the error by reconnecting cables one  at a time and rebooting until the error returns.
    2.  Check termination of identified channel in step 1a.

      Note: Refer to the HMM (Hardware Maintenance Manual) specific to the system comprising the  SCSI channel for termination details.

    3.  Disconnect one drive at a time attached to channel identified in step 1a and  reboot each time to determine which drive is causing the problem.
    4.  Replace SCSI Cable attached to channel identified in step 1a.
    5.  Replace Backplane attached to channel identified in step 1a.

  2.  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:
