Solution 1452064.1 : SUN4V-8002-KQ faults reported on T4-4, T4-2 and Netra T4-2 servers

Applies to:

Netra SPARC T4-2 Server
SPARC SuperCluster T4-4
SPARC T4-4
SPARC T4-2
SPARC
If the threshold level for ereport.cpu.generic-sparc.c2c-link@/host events is exceeded a FMA SUN4V-8002-KQ fault will be triggered by FMA.

Example:

root@ssccn4-m1:~# fmadm faulty

Description : The number of chip-to-chip recoverable errors has exceeded acceptable levels.

Purpose

This document outlines current support procedures for any of the T4-4, T4-2 and Netra T4-2 servers which have reported a SUN4V-8002-KQ fault.

Details

T4-4 servers only:

NOTE:6/5/2012 - FAB 1463634.1 is now released. If a SUN4V-8002-KQ occurs on a T4-4 server follow the procedures in the FAB

Download the Sun_SPARC_T4-4_PM_E0010556.pkg: Sun_SPARC_T4-4_PM_E0010556.zip

The FAB shows the installation using the CLI interface. Use of the WEB BUI is also supported.

T4-2 and Netra T4-2 servers:

When a Service Request is opened for a SUN4V-8002-KQ fault follow this process.

NOTE:This article does NOT apply to SUN4V-8002-MJ faults. See article 1180029.1 .

Review the previous service history for the system serial number checking for any previous reports of SUN4V-8002-KQ faults.

Another option is to review fma output explorer data. As long as prior fma data has not been purged any previous faults should be listed in the fmdump.out file in the fma directory.

Below is an example of a system where previous repairs were made but new SUN4V-8002-KQ faults occurred.

Process:

If this is the first time a SUN4V-8002-KQ fault has been reported the recommendation is to clear the FMA faults and power cycle the server.

From Solaris:
Use fmadm faulty to determine which device(s) have reported a SUN4V-8002-KQ fault.

For T4-2 the FRU listed will be /SYS/MB

#fmadm repaired /SYS/MB

#fmadm faulty

From ILOM

-> start /SP/faultmgmt/shell
Are you sure you want to start /SP/faultmgmt/shell (y/n)? y

faultmgmtsp> fmadm faulty -r
/SYS/MB

faultmgmtsp> fmadm repair /SYS/MB

faultmgmtsp> fmadm faulty -r

If this is a second fault and a single FRU on the T4-2 (System Board) is deemed faulted replace that FRU.
