The iSCSI Index for the storage node authorized to act
as a control node. This managed object is part of the
key to this table. This index provides a 1 to 1 mapping
to the node name in cIsnsCntlNodeIscsiNodeName. The
iSCSI node name is too long to be used for an index
directly. The iSCSI node index used for a specific
iSCSI node name MUST be identical in all DDs and
control node registrations. The mapping is persistent
across server reinitializations when the iSCSI node is
a member of a Discovery Domain (DD) or is a control
node. The managed object cIsnsNextIdxUnregIscsiNodeInDd
is used to determine an available index when an
unregistered iSCSI node is to be registered as a control
node prior to it being registered in the server using
the iSNS protocol.
