You can change the path policy with vicfg-mpath.

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

List all multipathing plugins loaded into the system. 

vicfg-mpath <conn_options> --list-plugins

At a minimum, this command returns NMP (Native Multipathing Plug-in) and MASK_PATH. If other MPP plug-ins have been loaded, they are listed as well.

2

Set the path policy by using ESXCLI. 

esxcli <conn_options> nmp device set --device naa.xxx --psp VMW_PSP_RR
3

(Optional) If you specified the VMW_PSP_FIXED policy, you must make sure the preferred path is set correctly.

a

Check which path is the preferred path for a device. 

esxcli <conn_options> storage nmp psp fixed deviceconfig get -d naa.xxxx
b

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.
