TitleWhat information should I provide to GTAC in the event of a process crash?
Question
What information should I provide to GTAC in the event of a process crash?
Environment
EXOS All
Answer
​There are several key pieces of information that will be needed to diagnose the root cause of a process crash.
  • Collect the output of show tech from the switch. This includes logs and other debug information from the switch. 
  • Upload any core dumps to a TFTP server using the upload debug command, and provide the files generated. See How to upload debug information to a TFTP server for detailed instructions on this.
  • Collect the output of show log messages nvram from the switch (from all nodes in a stack, or both MSMs or MMs on a chassis)
  • Also, provide information on any recent changes that have been made prior to the crash.

Providing this information when the case is initially opened will help streamline the process of diagnosing the process crash.
Additional notes
For more information on collecting the output of show tech, see How to collect a show tech from an EXOS switch

In a SummitStack, the command telnet slot <slot #> can be used to log into a different slot for collecting the output in step 3 above. In a chassis, the command telnet msm <a|b> or telnet mm <a|b> can be used.
