zone Alias Member List
1.3.6.1.4.1.9.9.294.1.1.9.1.3
The set of zone members which form this alias on this VSAN. The members of an alias are identified by the zoneMemberIndex object in the zoneMemberTable. If a particular bit has a value of '1', then the corresponding zone member is a part of this alias. All other zone members have '0' in their positions or not present in the string. This object is read-only; changes to its value are made by the agent as and when associated entries are created/deleted in the zoneMemberTable. The default value is the zero length string.
