Bug Id:
<SUNBUG: 6815610>

Product:
Sun Fire T2000 Server

Date of Workaround Release:
27-Mar-2009

Date of Resolved Release:
16-Apr-2009

***Checked for relevance on 23-Aug-2012***

1. Impact

A limited number of Sun Fire T2000 and SPARC Enterprise T2000 servers may experience a system shutdown after the System Controller (SC) Alert: "Chassis cover removed" is displayed on the console, causing system downtime.

In addition, this issue may result in unnecessary hardware replacement.

2. Contributing Factors

This issue can occur on the following platform:
  • Sun Fire T2000 Server without patch 139434-02
Note: This issue rarely occurs and has only been observed on the above mentioned T2000 server.

3. Symptoms

The system will report the following errors on the system console, which will also be recorded in the ALOM logs.  An example from 'showlogs -v' would be similar to the following:

      02:24:25: 0004007c: "System poweron is disabled."
      02:24:25: 00040083: "Chassis cover removed."
      02:24:25: 0004000e: "SC Request to Power Off Host Immediately."
      02:24:26: 0004004f: "Indicator SYS/ACT is now STANDBY BLINK"
      02:24:27: 0004007d: "System poweron is enabled."
      02:24:31: 00040029: "Host system has shut down."

As shown in the example, the key to identify this issue is that in the logs, the line "Chassis cover removed" will be followed by the line "SC Request to Power Off Host Immediately".  If the line "SC Request to Power Off Host Immediately" is missing from the above message, then this is a different issue and may indicate a hardware condition with the cover interlock switch.

4. Workaround

There is no workaround for this issue. Please see the Resolution below.

5. Resolution

This issue is addressed on the following platform:
  • Sun Fire T2000 Server with patch 139434-02 or later
