====== Monitoring du RAID HP Smart Array ======

===== Installer hpacucli =====

L'outil hpacucli permet de contrôler les cartes RAID depuis une machine Linux, en ligne de commande. Il faut récupérer le rpm sur le site d'HP [[http://downloads.linux.hp.com/SDR/downloads/PSP/RHEL/6/packages/x86_64/|ici]]

Voilà un petit script en perl qui permet de s'assurer de l'état des différent volumes logiques configurés:

<file perl check_raid_hp.pl>
#!/usr/bin/perl -w

use strict;
use Getopt::Long;

my $slot = '';
my $hpacucli = '/usr/sbin/hpacucli';
my @validchecks = qw/controller array logicaldrive physicaldrive/;
my $check = join ',', @validchecks;

GetOptions ('slot=s'  => \$slot,
            'check=s' => \$check,
            'help'    => sub { &usage() }
);

sub usage(){
    print <<"EOF";
$0 --slot=<slot number> --check=<what to check>

  * slot must be a number. You can find on which slot you have controllers with the command:

$hpacucli controller all show status

  * check is a comma separated list of item to check. Default values (without --check option) will check everything
    Valid values are:

EOF

    print "$_\n" foreach (@validchecks);
    exit(0);
}

if ($slot !~ /^\d+$/){
    usage();
}

unless (-x $hpacucli){
    die "Cannot run $hpacucli\n";
}

my @checks = split /\s?,\s?/, $check;
foreach my $check (@checks){
    usage() unless (grep { $_ eq $check} @validchecks);
}

foreach my $param (@checks){
    # Global controller checks
    if ($param eq 'controller'){
        open HPACUCLI, "$hpacucli controller slot=$slot show status|" ||
          die "An error occured while running $hpacucli: $!";
        foreach my $line (<HPACUCLI>){
            if ( $line =~ /Status\:\s*([\w\s]+)$/ ) {
                my $res = $1;
                chomp($res);
                if ($res ne 'OK'){
                    print "CRITICAL: $line\n";
                    exit(0);
                }
            }
        }
        close HPACUCLI;
    }
    else{
        open HPACUCLI, "$hpacucli controller slot=$slot $param all show status|" ||
          die "An error occured while running $hpacucli: $!";
        foreach my $line (<HPACUCLI>){
            if ( $line =~ /^\s*$param.*:\s*(\w+[\w\s]*)$/i ) {
                my $res = $1;
                chomp($res);
                if ($res ne 'OK'){
                    print "CRITICAL: $line\n";
                    exit(0);
                }
            }
        }
        close HPACUCLI;
    }
}

print 'OK';
exit(0);

</file>

Ce script affichera simplement "OK" sur la sortie standard si tout va bien, et sinon, il affichera CRITICAL suivie de la première ligne d'erreur rencontrée
