Configure multipath for the iSCSI volumes

About this task

To avoid any negative influence on VSAN performance, you must set multipath policy to Fixed and set Preferred Path on vmnic0. If you are using the extra ports on your VxRail (if equipped), set Preferred Path as the appropriate vmnic according to the extra ports.

Steps

  1. In the vCenter Client choose each host and navigate to Manage > Storage > Storage Device.
  2. Choose the iSCSI volume in the Storage Devices list.
  3. In the Properties tab, click Edit Multipathing….
    The Edit Multipathing Policies window is displayed.
  4. Select Fixed(VMware) for Path selection policy and then select the row in which Runtime Name contains C0.
  5. Click OK.

Results

In the Properties tab, the Path Selection Policy section shows Fixed(VMware) and vmhbaxx:C0:Tx:Lx.
