If you are extracting data from fixed width columns as seems to be the case here then you can use any of a number of techniques:

use strict;
use warnings;

my $table = <<DATA;
LV NAME               LPs   PPs   DISTRIBUTION          MOUNT POINT
loglv51               1     1     01..00..00..00..00    N/A
lvsapinst             64    64    54..10..00..00..00    /tmp/sapinst_i
+nstdir
lvusrsap              25    25    00..25..00..00..00    /usr/sap
DATA

open IN, '<', \$table;
while (<IN>) {
    chomp;

    my $name = substr $_, 0, 22;
    my $dist = substr $_, 34, 18;
    my $mount = substr $_, 56;

    print "$name $dist $mount\n";
}
close IN;

open IN, '<', \$table;
while (<IN>) {
    chomp;

    my ($name, $dist, $mount) = /(.{22}).{12}(.{18}).{4}(.*)/;

    print "$name $dist $mount\n";
}
close IN;

open IN, '<', \$table;
while (<IN>) {
    chomp;

    my ($name, undef, $dist, undef, $mount) = unpack ('a22a12a18a4a*',
+ $_);

    print "$name $dist $mount\n";
}
close IN;

Prints:

Interestingly, none of these use split.

Perl is environmentally friendly - it saves trees
