sometimes we might see the HP Smart Storage Array disk listed as a multipath device.
Most likely this device was not blacklisted in the blacklist section of the
/etc/multipath.conf file (do not forget to rebuilt the initial ramdisk after this)
e.g.
falsempathdev=$( multipath -l | grep "HP,LOGICAL" | awk '{print $1}' )  # mpatha

The purpose of this script is to uncomment these false multipath lines in the disklayout.conf file
adding /etc/multipath/wwids to prep/GNU/Linux/24_include_multipath_tools.sh
