Solaris LUN Online Report

If you are using fiber channel storage with Solaris in a multipath configuration, sometimes before fabric maintenance or array maintenance you might want to check and confirm the status of all the paths on the Solaris client.   The following script utilizing luxadm will report on the status of each path for a fiber channel device.

#!/bin/perl
@luns = `/usr/sbin/luxadm probe | grep Logical | sed -e 's/.*\://g'|grep rdsk`;
foreach $lun (@luns) {
        chomp($lun);
        $lun2 = $lun;
        $lun2 =~ s/\/dev\/rdsk\///g;
        print "Disk:$lun2\t";
        @luxadm = `/usr/sbin/luxadm display $lun`;
        $pathcount = 0;
        foreach $luxadm (@luxadm) {
                chomp($luxadm);
                if ($luxadm =~ /State/) {
                        $luxadm =~ s/State//g;
                        $luxadm =~ s/^\s+//;
                        print "Path$pathcount:$luxadm\t";
                        $pathcount++;
                }
        }
        print "\n";
}

The output from the script will look something like the output below:
