| 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 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.
For registered portals, the cIsnsDdMemberPortalIdx for a
specific cIsnsDdMemberPortalAddr and cIsnsDdMemberPortalPort
pair is obtained from the cIsnsRegPortalTable table.
For unregistered portals, if they are already a member of
other Discovery Domains, the same cIsnsDdMemberPortalIdx MUST
be used. For unregistered portals, if they are not already
a member of other Discovery Domains, then the managed object
cIsnsNextIdxUnregPortalInDd is used to obtain a valid
cIsnsDdMemberPortalIdx.
If a DD is removed from the iSNS, then all entries
associating portals with the DD are removed. |
