This object identifies the Pairwise role of the Zone/Zone alias
member.
If hh3cFcZsZoneMemberFormat is 'aliasName', the value of this
object can only be 'none'.
If hh3cFcZsZoneMemberFormat is not 'aliasName', the value of
this object can't be 'none', and the default value is 'both'
(including both 'initiator' and 'target' role).
This object can be modified while the value of the
hh3cFcZsZoneMemberRowStatus object is 'active'.
The Pairwise role of a port member takes effect only when the
hh3cFcZsZonePairwiseEnable of the Zone to which the port member
belongs is set to 'true'.
