Hi

Need to monitor the RAID Status of your Avago LSI Logic / Symbios Logic SAS3008 PCI-Express Fusion-MPT SAS-3 under Linux with perl?

Yes Avago has a crappy website. When you search the website for SAS3008 you only find some pdf. But not the utility to query your raid controller. Crappy website or intentionally. Who knows :-)

Below is a script which send’s a simple mail if something goes bad to your RAID. Just put it in your crontab. Might someone want’s to adopt it. Might use with Nagios/Icinga. Actually I’ve not the case to do this. Might later…

#!/usr/bin/perl

use warnings;
use MIME::Lite;

$emailFrom = 'root@server.domain.tld';
$emailTo = 'hostmaster@yourdomain.tpl';
$smartHost = 'smarthost.mail.local';
$hostName = 'server.domain.tld';
$pathSas3ircu = '/root/bin/SAS3IRCU_P12/sas3ircu_linux_x64_rel/sas3ircu';

if (check_status() == 1) {
  $body = join("", get_info("0","STATUS"));
  send_email($emailTo,$body);
}

sub check_status {
  $error = 0;

  foreach $line (get_info("0","DISPLAY")) {
    if ($line =~ /Status of volume/) {
      if ($line !~/Okay/) {
        $error = 1;
      }
    }
    if ($line =~ /State/) {
      if ($line !~ /Optimal/ ) {
        $error = 1;
      }
    }
  }
  return $error;
}

sub get_info {
  $arg1 = shift;
  $arg2 = shift;

  $cmd = "$pathSas3ircu $arg1 $arg2";
  @output = `$cmd`;
  return @output;
}

sub send_email {
  $arg1 = shift;
  $arg2 = shift;
  
  $subject = "Warning RAID inconsitent $hostName";

  $msg = MIME::Lite->new(
    From     => $emailFrom,
    To       => $arg1,
    Subject  => $subject,
    Data     => $arg2
  );

  $msg->send('smtp',$smartHost,Debug=>0);
}

EDIT 16.05.2018:
TomD kindly provided a simple nagios script:

#!/bin/bash

status=$(sas3ircu 0 STATUS | grep -o 'Optimal')
status1=$(sas3ircu 0 DISPLAY | grep -o 'OKY')

if [ "$status" =  "Optimal" ]
        then 
        if [ "$status1" =  "OKY" ]
                then 
                echo OK raid is good
                exit 0
fi
else
        echo Warn raid failed
        exit 1
fi

echo Critical raid failed
exit 3

Have Fun!
