Setting Round Robin path policy - Can I just use the GUI?

[thomps01]

I have HP EVA6400 arrays and also HP XP20000.

I am using ESX 4.1 U1 and the recommendation from HP is to use the Round Robin multipathing policy.

I assumed I could simply use the vSphere client and select configuration>storage>datastore>properties>manage paths>Round Robin>change

This approach would certainly changed the path policy for that server for the selected LUN, I would then repeat for each.

But, I read something on a blog lastnight which mentioned having to perform the path setting from the CLI using the esxcli nmp VMW_PSP_RR setting.

Can someone enlighten me please.

Thanks

you can use command line as well esxcli:

esxcli nmp device list

esxcli nmp device setpolicy --device <naa id> --psp VMW_PSP_RR

So what you're saying is that either can be used?

I'm guessing that if you change the default behaviour using the CLI then every LUN added to the host will actually use the Round Robin path policy without needing to go into the configuration section each time and setting this manually, is this correct?

yes, you can change for one lun and check in gui as well
