bdbe8dc662f9700c12eafcbcceb5c724615278cfPeter Cudhea - Sun Microsystems - Burlington, MA United States * (Corollary: Any time you remove the last registered target, you have
bdbe8dc662f9700c12eafcbcceb5c724615278cfPeter Cudhea - Sun Microsystems - Burlington, MA United States * to send an unregister-all message.)
bdbe8dc662f9700c12eafcbcceb5c724615278cfPeter Cudhea - Sun Microsystems - Burlington, MA United States * 3) If a target has a non-default portal, then the portal goes online
bdbe8dc662f9700c12eafcbcceb5c724615278cfPeter Cudhea - Sun Microsystems - Burlington, MA United States * before the target goes online, and comes offline afterwards.
bdbe8dc662f9700c12eafcbcceb5c724615278cfPeter Cudhea - Sun Microsystems - Burlington, MA United States * (This is enforced by the iscsit state machines.)
