PreviouslyPublishedAs

Product

Sun Fire V245 Server

Date of Resolved Release
05-Dec-2008

Sun Fire V215 and V245 servers may experience an erroneous transient overtemp alarm resulting in an abrupt power off of the system:

1. Impact

Sun Fire V215 and V245 servers may experience an erroneous transient "overtemp" alarm resulting in an abrupt power off of the system without a graceful shutdown of Solaris. When this occurs the "OVERTEMP LED" will be lit (amber) even though there is no genuine overtemp condition being experienced.

2. Contributing Factors

This issue can occur on the following platforms:

• Sun Fire V215 Server without patch 139735-01
  
• Sun Fire V245 Server without patch 139735-01

Note: This issue can occur on the systems listed above irrespective of the OS/ALOM versions in use.

3. Symptoms

If the described issue occurs, messages similar to the following will be seen in the ALOM event log ("showlogs" command):

    Feb 02 10:46:16 : 00040029: "Host system has shut down."
    Feb 02 10:46:56 : 00070002: "Indicator PS0.DC_OK is now OFF"
    Feb 02 10:46:56 : 00070002: "Indicator PS1.DC_OK is now OFF

In addition, the "OVERTEMP LED" on the front of the system chassis will be lit (amber). This LED status can also be confirmed with the ALOM "showenvironment" command. Meanwhile, all the sensors have an "OK" status.

Outputs similar to the following will be logged to "SYS.OVERTEMP":
