Ben Marzinski 2016-02-26 22:56:11 UTC Status ASSIGNED MODIFIED
Fixed In Version device-mapper-multipath-0.4.9-87.el7
Doc Text Feature: Add an optional argument to the alua prioritizer, "exclusive_pref_bit". If this argument is added, and a path has the TPGS pref bit set. Multipath will make a pathgroup using only that path, and assign it the highest priority

Reason: Some users want to use the TPGS pref bit to specify a single path that multipath should prefer to use. This was previously done. However, and change to how the priortizers worked make this no longer happen. This option restores the ability for those who need it.

Result: Users can now either allow the preferred path to be in a path group with other paths that are equally optimized (the default) or in a path group by itself (by adding the exclusive_pref_bit argument)

The "exclusive_pref_bit" optional argument has been added to the *multipath* ALUA prioritizer

If the "exclusive_pref_bit" argument is added to the *multipath* Asymmetric Logical Unit Access (ALUA) prioritizer, and a path has the Target Port Group Support (TPGS) pref bit set, *multipath* makes a path group using only that path and assigns the highest priority to the path. Users can now either allow the preferred path to be in a path group with other paths that are equally optimized, which is the default option, or in a path group by itself by adding the "exclusive_pref_bit" argument.

If the "exclusive_pref_bit" argument is added to the *multipath* Asymmetric Logical Unit Access (ALUA) prioritizer, and a path has the Target Port Group Support (TPGS) `pref` bit set, *multipath* makes a path group using only that path and assigns the highest priority to the path.
