This object indicates if the port FC addresses (given
by iscsi2FcPortFCAddrListIndex) of this node is made
persistent or not.
If this object is 'true', then the same FC address is
assigned to the ports of the node if it were to be
represented again in the FC domain with the same node
name. Note that the port FC address is either
automatically assigned or manually configured.
If this object is 'false', then iscsi2FcPortNumFCAddr
and iscsi2FcPortFCAddrListIndex are not valid as
port FC addresses are dynamically assigned/released.
