The multipath alua prioritizer now allows a an option, "exclusive_pref_bit"
If you use
prio "alua exclusive_pref_bit"
in your device configuration, multipath will create a pathgroup that only contains the path with the pref bit set, and will give that pathgroup the highest priority.
Oops. Comment 1 used the RHEL6 syntax. In RHEL7, you would add
to your device configuration. This is only used if you have
set as well.
