You are using the wrong path checker, wrong path priority program, and no hardware path checker :-( Here is what you need in your multipath.conf file: # # DELL :D3000i :: Active-Passive RDAC # Note: The same as the IBM DS3300 # device { vendor "DELL" product "MD3000i" product_blacklist "Universal Xport" features "1 queue_if_no_path" path_grouping_policy group_by_prio hardware_handler "1 rdac" path_checker rdac prio "rdac" failback immediate } Thought you might need to replace the 'prio "rdac"' with 'prio_callout "/sbin/mpath_prio_rdac" as I think RHEL5/CentOS5 uses the old calling convention. This should get rid of your down errors and show your passive/active path properly. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "open-iscsi" group.
