Symptoms

This document describes how to manage LSI RAID Controller 'failed' messages when a Sun Fire V440/V445 and/or Sun Netra 440 can't boot from any of its Internal Disks.

Error Messages:
All these messages can be seen at the ok prompt (OBP Level). They usually appear at the end of POST, but that does not mean the SCSI bus has failed. Please read below.

Example 1:

Example 2:

Example 3:

Cause

These failure messages from the LSI RAID Controller can be caused by different issues:

1. SCSI bus is not seeing the disks.
2. One or more disks has failed, so the SCSI bus is full of errors and the SCSI Controller can not properly access any device.

3. SCSI Backplane and/or the SCSI Backplane Cable are failing, which will impact the SCSI bus causing it to not allow access to the Disks.
4. Finally, the least likely cause of failure, is the LSI RAID Controller integrated into the Motherboard may be failing.

All these causes will prevent boot up the server from any Internal Disk.

Solution

At OBP Level, follow the steps below in order to isolate the failure:

1. Reset the SCSI bus and check if the disks can be seen. Run the following commands at the ok prompt:

1. ok reset-all
2. ok probe-scsi-all

2. If the Disks can not be seen, attempt to isolate failure to one of the internal disks being failed.  Replace any failed internal disks.

1. Visual verify if any fault lights on internal disks and replace if required.
2. Boot from alternate Solaris media and attempt to test internal disks with:
   # format
   * Analyze
   * Read
3. Replace any disks that do not respond or hang on the format/analyze/read command.

3. If unable to boot from alternate media, please do the following at OBP level:

1. Un-seat all internal disks
2. Change OBP parameter 'auto-boot?' for troubleshooting
   ok setenv auto-boot? false
3. Reset the server
   ok reset-all
4. Probe the scsi bus while you re-seat the Internal Disks one by one. After each Disk is re-seated, reset the system, then probe the scsi bus again
   ok probe-scsi-all
5. Pay attention to output on step d, if one of the disks is slow in response this could be an indication of a bad disk. Remove disk and probe scsi bus again, replace suspect disk that is slow in responding to the probe scsi output.

4. At this point, contact Oracle Support for any of this options:

1. Replace the faulty disk(s) isolated on previous steps.
2. Get assistance solving the issue if no disks are found faulty.

Additional troubleshooting steps:
5. If no internal disks can be isolated as faulty, then replace SCSI Backplane Cable to rule out cable failure.

6. If previous steps do not correct errors, then replace SCSI Backplane.

7. If issues persists, proceed with Motherboard replacement.

Be aware that the different HW parts can be FRU or CRU, depending on the Server.
