| Description | Each entry indicates an explicit addition of a portal to a
discovery domain. The explicit addition of an entity portal
to a discovery domain indicates the portal is preferred for
access to nodes of the entity for this discovery domain.
Registered Portal Group objects are used in iSCSI to
indicate mapping of portals to nodes across all discovery
domains. Portals that have been explicitly mapped to a
discovery domain will be returned as part of a query that
is scoped to that discovery domain. If no portal of an
entity has been explicitly mapped to a discovery domain,
then all portals of the entity that provide access to a
storage node are returned as part of a query. The table
indexes are the server instance, the DD ID of the Discovery
Domain, and the Portal Index of the portal. |
