Bug Description

When performing volume detach operation, NC try to detach first iISCSI volume it can see.

To reproduce, attach two volumes on the same instance and detach second volume. From NC's log we can see it try to detach first volume.

This may be caused by wrong string operator in
    if($_ =~ /Target: (.*)\n/) {
        $found_target = 1 if $1 == $store;
    } elsif($_ =~ /.*Attached scsi disk ([a-zA-Z0-9]+).*\n/) {
        if($found_target == 1) {

should be

    if($_ =~ /Target: (.*)\n/) {
        $found_target = 1 if $1 eq $store;
    } elsif($_ =~ /.*Attached scsi disk ([a-zA-Z0-9]+).*\n/) {
        if($found_target == 1) {

Using the eq operator to compare String instead.
