    Default values are set only for VMWARE EX and WIN EX host modes. The default for all other Host Modes is none.
    Ops Center Administrator identifies all host groups containing any of the server WWNs. If all of those host groups have the same host mode and host mode options, those settings are prepopulated with the same settings in the host groups.
  4. Select Mandate LUN Alignment.
    This option specifies whether to assign the same LUN number to multiple servers for volumes containing primary and secondary HA pairs. If Yes is specified, the same LUN number is always assigned. If No is specified, Ops Center Administrator tries to use the same LUN if it is available. If it is not available, Ops Center Administrator selects available LUNs separately for each primary and secondary volume.

  6. Leave ALUA set to Enabled to set preferred paths.
  7. You can confirm which Volume IDs will be used by clicking View Proposed Volume ID Selection.
