How a trace dump is used

The generation of a trace dump causes a CRITICAL message to be logged to the system error log. When
a trace dump is detected, issue the supportSave command on the affected switch. This command
packages all error logs, the supportShow output, and the trace dump, and moves these to your FTP
server. You can also configure your switch to copy trace dumps to your FTP server
automatic trace dump
In addition to automatic generation of trace dumps on faults, you can also generate a trace dump
manually or when certain system error messages are logged. This is normally done with assistance from
HP customer support when diagnosing switch behavior.
For details on the commands, see the HP StorageWorks Fabric OS 5.x command reference guide.

Setting up automatic trace dump transfers

You can set up a switch so that diagnostic information is transferred to a remote server. Then, if a problem
occurs you can provide your customer support representative with the most detailed information possible.
To ensure the best service, you should set up for automatic transfer as part of standard switch
configuration, before a problem occurs.
Setting up for automatic transfer of diagnostic files involves the following tasks:
• Specify a remote server to store the files.
• Enable the automatic transfer of trace dumps to the server. (Trace dumps overwrite each other by
default; sending them to a server preserves information that would otherwise be lost.)
You should also set up a periodic checking of the remote server so that you are alerted if the server
becomes unavailable and you can correct the problem. See the HP StorageWorks Fabric OS 5.x
administrator guide for additional information.
