Solution 1918727.1 : Sun Fire T4-1 server flooding the console with message "Cannot open /dev/sptrace"

Applies to:

SPARC T4-1 - Version All Versions to All Versions [Release All Releases]
Information in this document applies to any platform.

Symptoms

After MB replacing the ILOM started to show these messages

Cannot open /dev/sptrace
Cannot open /dev/sptrace
Cannot open /dev/sptrace
Cannot open /dev/sptrace
Cannot open /dev/sptrace
Cannot open /dev/sptrace
Cannot open /dev/sptrace
Cannot open /dev/sptrace
Cannot open /dev/sptrace
Cannot open /dev/sptrace
Cannot open /dev/sptrace
Cannot open /dev/sptrace

Changes

After MB replacing and booting the server for first time.

Cause

Errors continuously appeared on the console connected through the serial management port during ILOM starting up.
The server reached OK prompt although 'Cannot open /dev/sptrace' messages were reported endlessly.

The message is flooding the console
Cannot open /dev/sptrace
Cannot open /dev/sptrace
Cannot open /dev/sptrace
Cannot open /dev/sptrace
Cannot open /dev/sptrace
Cannot open /dev/sptrace
Cannot open /dev/sptrace
Cannot open /dev/sptrace
Cannot open /dev/sptrace
Cannot open /dev/sptrace
Cannot open /dev/sptrace
Cannot open /dev/sptrace

As this would be an issue with setting up the sptrace device, it will take an SC reset to clear, and an SC reset to hit.
This behavior has also been reported on the Netra T4-1

Solution

Reset the Service Processor, if the reset doesn't resolve, remove AC to powercycle and reboot the Service Processor.
