HP 3Par with Hypervisor 8.2 and Multipathing

Robert Madrian



since HP 3PAR Version OS 3.3.x the Host Persona changed from 1 - Generic to 2 - Generic-ALUA.

In the 3Par Management it is only possible to select Xenserver 7.x which sets Host Persona to 1-Generic but these doesn't work with the settings in multipath.conf



device {
          vendor "3PARdata"
          product "VV"
          features "0"
          path_selector "round-robin 0"
          path_grouping_policy "group_by_prio"
          hardware_handler "alua"
          prio "alua"
          failback "immediate"
          rr_weight "uniform"
          no_path_retry 18
          rr_min_io 100
          path_checker "tur"
          fast_io_fail_tmo 20
          dev_loss_tmo "infinity"


I have now set this to RHEL Virtualization 7.x which set it to 2 - Generic-ALUA and now multipath works but don't know if there are other consequences with this setting except
the Persona?





Anybody out there which uses Hypervisor 8.2 Multipathing with HP 3Par?
