HP 3Par with Hypervisor 8.2 and Multipathing


Robert Madrian

Question

Hello,

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?

 

Robert
