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 automatically copy trace dumps to your FTP server (see
” Setting up automatic trace dump transfers ”).
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, refer to the HP StorageWorks Fabric OS 4.x command reference guide.
Setting up automatic trace dump transfers
You can set up a switch so that diagnostic information is transferred automatically to a remote server. If a
problem then 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 entails the following tasks:
• Specifying a remote server to store the files.
• Enabling 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.)
