304 Working with diagnostic features
Viewing and saving diagnostic information
Enter the
supportShow
command to dump important diagnostic and status information to the session
screen, where you can review it or capture its data.
To save a set of files that customer support technicians can use to further diagnose the switch condition,
enter the
supportSave
command. The command prompts for an FTP server, packages the following files,
and sends them to the specified server:
• the output of the
supportShow
command
• the contents of any trace dump files on the switch
• system message logs (for Directors,
supportSave
saves the system message logs from both of the CP
blades)
Refer also to ” Setting up automatic trace dump transfers ” on page 304, next.
Setting up automatic trace dump transfers
You can set up a switch so that diagnostic information is transferred automatically 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.
After the setup is complete, you can run the
supportSave -c
command to save diagnostic information
to the server (without specifying server details).
The following procedures describe in detail the tasks for setting up automatic transfer. For details on the
commands, refer to the Fabric OS Command Reference Manual .
To specify a remote server
1. Verify that the FTP service is running on the remote server.
2. Connect to the switch and log in as
admin
.
3. Enter the following command:
The command is interactive; provide the required information.
4. Respond to the prompts as follows:
switch:admin> supportftp -s
Host Name
Enter the name or IP address of the server where the file is to be stored; for
example, 192.1.2.3.
User name
Enter the user name of your account on the server; for example,
“JohnDoe”.
Password
Enter your account password for the server.
Remote
Directory
Specify a path name for the remote Directory. Absolute path names can be
specified using forward slash (/). Relative path names create the Directory
in the user’s home Directory on UNIX servers, and in the Directory where
the FTP server is running on Windows servers.
