Support

Fabric OS creates a number of files that can help support personnel troubleshoot and diagnose a
problem. This section describes those files and how to access and/or save the information for
support personnel.

Panic Dump and Core Dump Files

The Fabric OS creates panic dump files and core files when there are problems in the Fabric OS
kernel. You can view panic dump files using the pdShow command. These files can build up in the
kernel partition (typically because of failovers) and might need to be periodically deleted or
downloaded using the supportSave command.
The software watchdog process (SWD) is responsible for monitoring daemons 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. The ping interval is set at 133 seconds, with
the exception of the Fabric Watch daemon and the IP storage demon, which ping the SWD every
333 seconds. (For a complete listing of daemons, see the KSWD entry in
If a daemon fails to ping the SWD within the defined interval, or if the daemon terminates
unexpectedly, then the SWD dumps information to the panic dump files, which helps to diagnose
the root cause of the unexpected failure.
Run the pdShow command to view these files or the supportSave command to send them to a host
workstation using FTP. The panic dump files and core files are intended for support personnel use
only.

Trace Dumps

The Fabric OS produces trace dumps when problems are encountered within Fabric OS modules.
The Fabric OS trace dump files are intended for support personnel use only. You can use the
supportSave or supportFTP commands to collect trace dump files to a specified remote location to
provide to support when requested.

supportSave Command

The supportSave command can be used to send the output of the system messages (RASLog), the
trace files, and the output of the supportShow command to an off-switch storage location through
FTP. Prior to running the supportSave command, you can optionally set up the FTP parameters
using the supportFtp command. The supportShow command runs a large number of dump and
show commands to provide a global output of the status of the switch. Refer to the Fabric OS
Command Reference for more information on these commands.

NOTE
Any reference seen in a system message to slot 0 is a reference to the blade within the switch
platform, for example: Brocade DCC contains FC8-48, FC9-32, and FC8-16 blades.
