-                               <p>At the moment, if security name for an initiator reassigned (moved) to another security
-                               group, the existing sessions from that initiator are not automatically reassigned to
-                               the new security group, i.e. they remain in the old one. The only ways to reassign them
-                               are either sessions restart, or restart of the corresponding target driver. Both in many
-                               cases are not options.</p>

-                               <li><span>Globally suspend all activities by scst_suspend_activity().</span></li>
-                                  
-                               <li><span>Go over all existing sessions. For each find the corresponding ACG 
-                                     (see scst_init_session() as an example) and check if it's the same as the existing 
-                                     one. If it's the same, then go to the next session. Otherwise, reassign 
-                                     it to the new ACG. For that you should go over all devices in the group/session 
-                                     pair (tgt_dev's) and delete not existing in the new ACG tgt_dev's, 
-                                     add new ones and keep the existing ones.</span></li>
