About Custom Commands
Custom commands let you run a command that you create on the management server. The
command could point to an executable or a script that does not use the graphical user interface. For
example, assume you have already created a script that backs up a storage system. You could run
that script from System Manager.
You can also use environment variables in your scripts. For example, you could use the variables to
obtain information about a host, such as its total physical memory and the number of processors.
Important Considerations
Keep in mind the following:
• Run scripts at your own risk. The management server lets you run any script, including those that
can disable the management server.
• The custom command always runs on the management server unless you are running the telnet
utility. You can obtain information about an element on which you right-click by using the
software's environment variables. See ”Software Environment Variables for Scripting” on
page 295.
• Custom commands only supports executables and scripts that do not use the graphical user
interface.
• Management servers on Windows only: If you leave the remote console (cmd /k) open after
running a script, users can traverse the directory structure of the management server.
• If you want a Perl script to run as a custom command on a UNIX system, you must prefix the
script with the Perl executable, for example, perl myscript.pl, where myscript.pl is the
script you want to run. A best practice is to prefix the script with the path to Perl and the Perl
executable, for example: perl/bin/perl myscript.pl, where perl/bin/ is the directory
containing the Perl executable, perl is the executable and myscript.pl is the script you
want to run.
