Brocade SAN switches port count

We manage more than 100+ SAN switches in our storage infrastructure. Keeping track of port availability, status and count are hectic capacity management tasks. If we need to get this data manually, we need to login to each switch, run commands, grab output, do the math and tabulate values. Storage admin job is not an easy one to do!!

Using PERL script we can simplify these tasks. Below PERL script would help us to get above information in a matter of seconds. This output can be exported to excel for further beatification 🙂

use Net::SSH2;
use POSIX;
use MIME::Lite;
open (INPUT, "emc_switch_ips.txt");
my @ip =< INPUT>;
my ($sec,$min,$hour,$mday,$mon,$year,$wday,$yday,$isdst) = localtime(time);
my $datestring = sprintf("%02d_%02d_%02d_%02d_%4d",$hour,$min,($mon+1),$mday,($year + 1900));
open OUTPUT, '+>', "emc_result-$datestring.txt" or die $!;
STDOUT->fdopen( \*OUTPUT, 'w' ) or die $!; # redirecting the STDOUT to file
open (PASS, "pass");
use constant BUFLEN => 10_0000 ;
my $user = "admin";
my $password = ;
my $cmdlet = ("switchshow | grep id");
foreach $switch(@ip){
print "$switch - Total number of ports\n";
my $ssh = Net::SSH2->new();
                print("Connection Failed\n");
                print("Authentication Failed");
my $channel = $ssh->channel();
my $command = $channel->exec("$cmdlet") or die $_;
	my $read = $channel->read($buf, BUFLEN );
	warn 'More than ', BUFLEN, ' characters in listing' if $read >= BUFLEN;
	print $buf;
my @data = split (/\n/,$buf);
for ($i=0;$i<$len;$i++){
#print "@data[$i] \n";
@on[$i] = grep (/Online/,@data[$i]);
@no[$i] = grep (/No_Light/,@data[$i]);
#print "Online: @on[$i] \n";
#print "Offline: @no[$i] \n";

We need to have a text file with SAN switches IP addresses called “emc_switch_ips.txt” also we need to store user password in a file called “pass”. Thats it! go to shell / CMD and execute the file which gives below output.

1 1 010100 id N8 No_Light FC

  1. Hi Vinay,

    Your articles are really helpful. Cud u help me on the below query?

    – Total number of ports
    Authentication Failed

    My pl Script is working fine with normal IP but it is throwing error in NAT IP. Is there any pl module to access devices with NAT ips? or How to fix this?

    Grateful if you could mail me on this.


    1. Hi thanks for stopping by Please liaise with network team who would be able to help you to identify if its is a firewall or connectivity issue.
