    multipath.conf for oel 6.4 and oracle zfs appliance

    user2133045
      i have a zfs 7320 storage appliance connected via brocade fiber switches to clustered linux servers. one zfs controller with four fiber connections each server has two fiber connections. there are redundant switches so zfs is connected with two fiber connections to each switch and each server is connected one fiber connection to each switch. the zfs appliance manual does not have oel or redhat or any other similar 6.x multipath configuration. oracle support or sales has not been able as of yet to find multipath config for 6.x and suggested i post it here. Since I had issues that seem to be resolved with new zfs appliance software I want to verify my multipath config before i put the unit back in production, I would feel much better with a known good config.

      This is what is in the manual for 5.x linux:

      device
      {
      vendor "SUN"
      product "Sun Storage 7310" or "Sun Storage 7410" (depending on storage system)
      getuid_callout "/sbin/scsi_id -g -u -s /block/%n"
      prio_callout "/sbin/mpath_prio_alua /dev/%n"
      hardware_handler "0"
      path_grouping_policy group_by_prio
      failback immediate
      no_path_retry queue
      rr_min_io 100
      path_checker tur
      rr_weight uniform
      }

      This is what seems to work with 6.x:

      device {
      vendor "SUN"
      product "ZFS Storage 7320"
      getuid_callout "/sbin/scsi_id --whitelisted --replace-whitespace --device=/dev/%n"
      prio alua
      hardware_handler "0"
      path_grouping_policy group_by_prio
      failback immediate
      no_path_retry queue
      rr_min_io 100
      path_checker tur
      rr_weight uniform
      }
