This read-create TruthValue marks whether a given VMPS entry is the primary server the switch should use as its current server; setting one entry true automatically transitions any other entry from true to false, attempting to set an entry to false directly after creation returns a bad value error, and deleting the current primary entry causes the first remaining entry to become primary. An admin cares because this exclusive-primary behavior determines exactly which VMPS server the switch will query, with automatic failover semantics on deletion. For example, an operator wanting to switch which VMPS server is authoritative would set the desired entry's vmVmpsPrimary to true, which automatically demotes whichever entry was previously primary.
