The first part checks for the filesystem type.. zfs - do nothing, since it doesn't use SVM... the 2nd part of the if statement processes the ufs part, by running metastat -p and counting the number occurrences of the letter d... for a mirror with 2 plexes it should be 3, one for the metadevice, and one for each plex. Anything less than 3 gets thrown out as being unsynched. The $mirror_cmd is the metastat -p |grep m to get the metadevices only.

Here is the while loop for that part of the code:
        while ( defined ($line = $ssh->read_line()) ) {
                if($line =~ m/zfs/) {
                        open(MIR,">>$MIRRORS");
                        print MIR "$_ - has ZFS root, no metadevices e
+xist\n";
                        close(MIR);
                }
                else {   # Not ZFS, presumably ufs
                        # Execute SVM Mirror check - looking for unsyn
+ched mirrors
                        my $mirror_output = $ssh->send("$mirror_cmd");
                        my $line2;
                        while ( defined ($line2 = $ssh->read_line()) )
+ {
                                my $tmpcount = ($line2 =~ tr/d//);
                                if($tmpcount < 3) {
                                        open(MIR,">>$MIRRORS");
                                        print MIR "$_:  ";
                                        chomp();
                                        print MIR "$line2 - Not Mirror
+ed\n";
                                        close(MIR);
                                }


                        }
                }
        }

On a side note, apparently setting PS = ; had no effect, because it's still showing the same output as earlier.

Thanks!
