Responding to a System Message

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 Table 5, KSWD.)

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 dumps 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 via 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.
