HP MSA 2040 CLI Reference Guide

14 Using the CLI
Using CLI interactively
By default the CLI is an interactive application. When you are logged into the CLI, the CLI waits for a
command to be entered and then responds to it.
The following example shows interactively starting a Telnet session, logging into the CLI, executing a
command to show free (available) disks, and exiting the CLI:
$: telnet IP-address

Using a script to access the CLI
The following example shows how to construct a Perl script to communicate with the CLI via Telnet. cLogin
is called at the start of the script to log a user into the CLI. The script uses the command-line parameters
specified as the IP address, username, and password. After the user has been logged in, other commands
can be sent to the CLI.
use Net::Telnet;
sub cLogin {
$telnet->open($_[0]);
$telnet->waitfor(/(login|username)[: ]*$/i);
$telnet->print("$_[1]");
$telnet->waitfor(/password[: ]*$/i);
$telnet->print("$_[2]");
# either got a login or a prompt
@ok = $telnet->waitfor(/(#|login:*) /i);
if ($debug_commands == 1) { print "-"; print @ok; print "-\n"; }
if ($ok[1] =~ m/login/gi)
{
return 0;
}
else
{
return 1;
}
