This section provides procedures on gathering information on RASLog messages.
Looking up a message: This document arranges messages alphabetically by Module ID and then numerically within a given module. To look up a message, copy the module (see Table 9 System module descriptions) and error code and compare them with the Table of Contents or look up lists to determine the location of the information for that message.
Message text
Perform the following steps and ask yourself these questions when troubleshooting a system:
- Is the switch down?
- How large is the fabric?
- Is the fabric redundant?
• Execute the show logging raslog command on each switch.
• Execute the copy support command.
• Document the sequence of events by answering the following questions:
- What happened just before the problem?
- Is the problem repeatable?
- If so, what are the steps to produce the problem?
- What configuration was in place when the problem occurred?
• Did a failover occur?
• Was Power-On Self-Test (POST) enabled?
• Are serial port (console) logs available?
• What and when were the last actions or changes made to the system?
SLX-OS creates several files that can help support personnel troubleshoot and diagnose a problem. This section describes those files and how to access and save the information for support personnel.
Panic dump, core dump, and FFDC data files: SLX-OS creates panic dump files, core files, and FFDC data files when problems in the SLX-OS kernel occur. You can view files by using the show support command. These files can build up in persistent storage and may need to be periodically deleted or downloaded by using the copy support command.
The software watchdog (SWD) process is responsible for monitoring daemons that are critical to the function of a healthy switch. The SWD holds a list of critical daemons that ping the SWD periodically at a predetermined interval defined for each daemon.
If a daemon fails to ping the SWD within the defined interval or the daemon terminates unexpectedly, the SWD dumps information to the panic dump files, which helps to diagnose the root cause of the unexpected failure.
Enter the show support command to view these files or the copy support ftp command to send them to a host workstation using FTP. The panic dump files, core files, and FFDC data files are intended for support personnel use only.
Trace dumps: SLX-OS produces trace dumps when problems are encountered within SLX-OS modules. The SLX-OS trace dump files are intended for support personnel use only. You can use the copy support command to collect trace dump files to a specified remote location to provide support when requested.
Using the copy support command: The copy support command is used to send the output of the RASLog messages, trace files, and output of the copy support command to an off-switch storage location through FTP. You can upload support save data from the local switch to an external host or save the data on an attached USB device. The copy support command runs a large number of dump and show commands to provide a global output of the status of the switch. Refer to the Extreme SLX-OS Command Reference for more information on the copy support command.
