You can change the path policy with ESXCLI.

Specify one of the options listed in Connection Options for vCLI Host Management Commands in place of <conn_options>.

Prerequisites

Verify that you are familiar with the supported path policies. See Managing Path Policies.

Procedure

  1. Ensure your device is claimed by the NMP plug-in.
    Only NMP devices allow you to change the path policy.
    esxcli <conn_options> storage nmp device list
  2. Retrieve the list of path selection policies on the system to see which values are valid for the --psp option when you set the path policy.
    esxcli storage core plugin registration list --plugin-class="PSP"
  3. Set the path policy by using ESXCLI.
    esxcli <conn_options> storage nmp device set --device naa.xxx --psp VMW_PSP_RR
  4. (Optional) If you specified the VMW_PSP_FIXED policy, you must make sure the preferred path is set correctly.
    1. Check which path is the preferred path for a device.
      esxcli <conn_options> storage nmp psp fixed deviceconfig get --device naa.xxx
    2. If necessary, change the preferred path.
      esxcli <conn_options> storage nmp psp fixed deviceconfig set --device naa.xxx --path vmhba3:C0:T5:L3
      The command sets the preferred path to vmhba3:C0:T5:L3. Run the command with --default to clear the preferred path selection.
