        devnode sda
        wwid 36782bcb01a516500157bb46c465037fe

        device {
               vendor DELL.*
               product PERC.*

        multipath {
                wwid    360060e80105af290057037b900000000
                alias   LUN-HITACHI

devices {
                 vendor                   "HITACHI"
                 product                  "DF600F"
                 path_grouping_policy     multibus
                 prio_callout             "/sbin/mpath_prio_hds_modular %d"
                 getuid_callout           "/lib/udev/scsi_id -g -u -d /dev/%n"
                 path_checker             readsector0

                 failback                 15

act@BIOPACS:~$ sudo multipath -ll
[sudo] password for act:

36782bcb01a516500157bb46c465037fe: map in use

act@BIOPACS:~$ sudo multipath -F
