Additional SWAP space not being activated after reboot of server

Issue

• The system is unable to automatically activate swap created on multipath devices after reboot:

  $ cat /etc/fstab |grep -i swap|grep -i mpath
  /dev/mapper/mpath18        swap                    swap    sw,pri=60        0 0
  

  o Once the system has finished boot process, swap filesystem created over multipath device could be activated manually using following command:

  $ swapon -v -p 60 /dev/mapper/mpath18
