======Bareos SD power on/off======
=====Introduction=====
I have a SAS tapedrive connected to a dedicated server for backups. On this machine bareos-sd is running. I do not want the bareos-sd server powered on all the time when it is only backup-ping a litte time of the day.

So I have made some scripts to power on and off the server.
The server is a Supermicro machine with IPMI, so I am using ipmiutils to power on/off the machine.

=====Powering off the SD=====
The catalog backup runs with a lower priority so shutting down the server after the catalog backup makes sense. In a schedule I always end with creating a catalog backup. When the SD is powered down, I do not want to power it down again.

=====Catalog backup=====
<code - /etc/bareos/bareos-dir.d/job/catalog.conf>
Job {
  Name = catalog
  Client = backup-mngt-bh
  Type = Backup
  Level = Full
  Storage = disk-bh
  Pool = disk
  Messages = Standard
  FileSet = catalog
  Schedule = catalog

  # Default
  #RunBeforeJob = /usr/lib/bareos/scripts/make_catalog_backup
  # Helux
  RunBeforeJob = /usr/lib/bareos/scripts/make_catalog_backup.sh
  # Default
  #RunAfterJob  = "/usr/lib/bareos/scripts/delete_catalog_backup"
  # Helux
  RunAfterJob  = "/usr/lib/bareos/scripts/delete_catalog_backup.sh"
#  Write Bootstrap = "|/usr/bin/bsmtp -h localhost -f \"\(Bareos\) \" -s \"Bootstrap for Job %j\" root@localhost" # (#01)
  Priority = 11
}
</code>

=====Powering on the SD when running a job=====
When I need to write a backup to the bareos-sd server, I need to power it on. But I do not want to power it on when it is already on. It is possible a job will be triggered with another job still running.
<code - /etc/bareos/bareos-dir.d/job/example.conf>
Job {
  .
  .
  .
  RunBeforeJob = /usr/lib/bareos/scripts/poweron_bareos_sd.sh
}

function check_bareos_sd {
  nc -w1 $BAREOS_SD_IP $BAREOS_SD_PORT < /dev/null 2>/dev/null
  if [ $? -eq 0 ]; then
  # if return value is 0 then port is reachable so we can exit the function with value 0
    return 0
  else
    return 1
  fi
}

while true; do
  check_bareos_sd
  if [ $? -eq 0 ]; then
    # We are online, so exit loop
    exit 0
  else
    # We are offline, so add 1 to counter, sleep for $SLEEP seconds and continue loop
    # $COUNT=0 then we can power on the machine using ireset (ipmiutil)
    if [ $COUNT -eq 0 ]; then
      ireset -u -N $IPMI_IP -U $IPMI_USER -P $IPMI_PASS >/dev/null 2>&1
    fi
    let COUNT=$COUNT+1
    sleep $SLEEP
  fi
  # check if $COUNT reaches $NUM_TRIES and when it does exit with value 1
  if [ $COUNT -eq $NUM_TRIES ]; then
    exit 1
  fi
done
