Maybe I should have been more clear, but it´s the fence_scsi on emcpower
path that is untested/unsupportedd. Both taken separately are.

It might very well work, but I can´t sign it off :)

you can try fence_sanlock, but again, untested over emcpowerpath (Tech
Preview in RHEL).

https://alteeve.ca/w/Watchdog_Recovery has a good tutorial.

If you are deploying with RHEL (and not Centos) then I suggest you also
contact GSS to have a review of your cluster architecture and make sure
there are no other caveats in that setup.
