Predictive Self-Healing Article
Hard-to-diagnose failure of the XSCF has occurred.

Type

: upset; upset.chassis.SPARC-Enterprise.xscfu

Severity

: Minor

Description

: A hard-to-diagnose failure of the XSCF has occurred.

Automated Response

: The XSCFU will reboot. If the configuration has redundant XSCFU's, the standby XSCFU may take over as the active XSCFU.

Impact

: The XSCFU will reboot. If the configuration has redundant XSCFU's, the standby XSCFU may take over as the active XSCFU. There is no impact to the domains.

Suggested Action for System Administrator

: Please consult the detail section of the knowledge article for additional information.

Details

: Hard-to-diagnose failure of the XSCF has occurred.

This fault may occur either due to a hardware or software problem on the XSCFU.

The XSCFU will reboot.

The precise cause of failure can be identified from the ereport class.

The 3 types of failures that can be detected are as follows:

Unexpected Failover
The standby XSCF took over control and became the active XSCF, without an organized handover from the active XSCF.;         SPARC Enterprise M8000/M9000 platforms:
          Nothing is deconfigured and no immediate action is taken.

   Process Timeout
      During XSCF startup or transition from XSCF standby state to XSCF active state, a timeout occurred.

         SPARC Enterprise M3000/M4000/M5000 platforms:;             When the XSCF detects the problem, the XSCF reboots.

         SPARC Enterprise M8000/M9000 platforms:
            If the XSCF that detected the problem is the active XSCF, then the standby XSCF will likely take over as active XSCF.

   Process Down

      XSCF process terminated due to what is most likely a XSCFU hardware problem.

         SPARC Enterprise M3000/M4000/M5000 platforms:

            When the XSCF detects the problem, the XSCF reboots.

         SPARC Enterprise M8000/M9000 platforms:

            If the XSCF that detected the problem is the active XSCF, then the standby XSCF will likely take over as active XSCF.

The platform administrator should investigate whether there was a hardware failure of the XSCFU or a software failure of the XSCFU software.

Step 1. Collect a snapshot ( See doc 2097446.1 - SPARC Mx000 and M10-x systems: Simple Instructions to Collect an XCP Snapshot ).
Step 2. Contact your Authorized Service Provider.
