Multipath settings for Oracle VM hosts

Edit online

When you attach the system to Oracle VM hosts, certain settings are recommended.

The following examples provide the settings for attaching the system to a host that is running Oracle VM:
device {
               vendor "IBM"
               product "^2145"
               path_grouping_policy group_by_prio
               path_selector "round-robin 0"
               path_checker tur
               features "1 queue_if_no_path"
               hardware_handler "0"
               prio alua
               failback immediate
               rr_weight uniform
               rr_min_io_rq 1
               fast_io_fail_tmo 5
               dev_loss_tmo  infinity 
       }
Edit the /etc/sysconfig/o2cb file to configure the Oracle VM system heartbeat where timeout is the Oracle VM system timeout:
o2cb_heartbeat_threshold = (timeout/2) + 1 
o2cb_idle_timeout_ms = (timeout/2) * 1000
