Solution 1332034.1 : Unable To Boot The Domain due to "No usable Cpu board or IO board in domain"

Applies to:

Sun Fire 6800 Server - Version: Not Applicable and later   [Release: N/A and later ]
Sun Fire E6900 Server - Version: Not Applicable to Not Applicable   [Release: N/A to N/A]
Sun Fire 4800 Server - Version: Not Applicable to Not Applicable   [Release: N/A to N/A]

Information in this document applies to any platform.

Symptoms

=== Issue Clarification ===

For any Mid-Range Servers, you will not be able to boot a domain due to the fact that the minimum number of CPU or IO board in the domain is not present.

=== Issue Verification ===

To check for Hardware failure, the SA need to log into the Main system controller
and on the Platform shell execute these commands to confirm that there are hardware failures preventing the domain from booting.

sc> showboards -v
sc> showcomponent -v
sc> showlogs -v
sc> showlogs -d <domain-id>
sc> showplatform
sc> showchs -b
sc> showerrorbuffer

The key message indicator in such a situation is "No usable Cpu board in domain" seen in the showlogs -v output.

In this example, the domain-B has only one IB8 and one SB5, both of which have been marked as failed. This will prevent the domain from booting, even if either one of the boards is marked as failed.

Thorough investigation is required from Oracle and an 'explorer -w scextended' needs to be sent to Oracle for further investigation. See Document 1019066.1

If an explorer cannot be gathered for some reason, see Document 1003529.1 that outlines the commands to collect data from the SC manually.

XXX:SC> showboards -v

Cause

Hardware Failure located on SB5 and IB8 in this example

Solution

For this example, FE must take these actions:

1.- Replace the SB5
2.- Replace the IB8
3.- Run post with diag level set to max (or mem2 if memory is suspect)
4.- Boot the domain and confirm if the system is working fine.
