I think the easiest it to increase the node.session.timeo.replacement_timeout in /etc/iscsi/iscsid.conf to something more than default 120 seconds (which means that the connection is dropped after 2 minutes; if you want to upgrade your target server and change the cabling, you may need more time than two minutes). -- Tomasz Chmielewski http://wpkg.org --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "open-iscsi" group.
