If you do this: 1. set DISCOVERY AUTHENTICATION in iscsid.conf. 2. run discovery iscsiadm -m discovery -t st -p ip 3. set NODE AUTHENTICATION for target1 found iscsiadm -m node -T target1 -p ip:port -o update -n node.session.auth.username -v user iscsiadm -m node -T target1 -p ip:port -o update -n node.session.auth.password -v pass 4.A If other target or portal or both is found through the same discovery address and was just found then all you have to do is run those iscsiadm -m node commands for the second target (you do not need to run discovery again): iscsiadm -m node -T target2 -p ip2:port -o update -n node.session.auth.username -v user iscsiadm -m node -T target2 -p ip2:port -o update -n node.session.auth.password -v pass 4.B if the other target or portal or both is found through a different discovery address but using the same DISCOVERY AUTHENTICATION then do discovery to the other address: iscsiadm -m discovery -t st -p ip2 If for some reason the other discovery address also gives you the targets and portals from the other discovery address ip, then pass in the -o new -o delete to the discovery command. Then run iscsiadm -m node -o update .... to set the NODE AUTHENTICATION for those targets. 4.C if the other target or portal or both is found through a different discovery address but using a differenet DISCOVERY AUTHENTICATION then you have to edit the discovery chap settings in iscsid.conf and then run the discovery command iscsiadm -m discovery -t st -p ip2 If for some reason the other discovery address also gives you the targets and portals from the other discovery address ip, then pass in the -o new -o delete to the discovery command. Then just run iscsiadm -m node -o update .... to set the chap settings for the targets found in there. 5. if then later on you want to discover new targets then run iscsiadm -m discovery -t st -p ip -o new -o delete And then run iscsiadm -m node -o update .... to set the chap settings for what was found. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "open-iscsi" group.
