Hello List, i am trying to set up multipathd with a Qlogic FC HBA. In my debian squeeze i can see 4 scsi devices: - sda - sdb - sdc - sdd Here my /etc/etc/multipath.conf file (this config is kind of guessed): I actually would like to have redundancy/fallback, not round robin....: =============================================== blacklist { devnode "sda" devnode "^(ram|raw|loop|fd|md|dm-|sr|scd|st)[0-9]*" devnode "^hd[a-z][[0-9]*]" } defaults { user_friendly_names no udev_dir /dev polling_interval 10 verbosity 3 path_grouping_policy failover } multipaths { multipath { wwid 3600a0b80001f7557000032864ce4aff3 alias SAN path_grouping_policy failover path_selector "round-robin 0" failback manual rr_weight priorities no_path_retry 5 rr_min_io 100 } } devices { device { vendor "IBM" product "1722-600" path_grouping_policy failover } } However, i dont seem to get a device-mapper device.
