Change the Path Policy with ESXCLI

You can change the path policy with ESXCLI.

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

Prerequisites

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

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
```
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"
```

Set the path policy by using ESXCLI.

esxcli <conn_options> storage nmp device set --device naa.xxx --psp VMW_PSP_RR

(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.
