CloudForms worker direct mount LUN question

Hi,

I'm installing CF on a RHEV Lab.

I've deployed UI/DB and a worker, but noticed that the docs mention the worker must direct mount the storage LUN in iSCSI/FC

is this really a requirement? It mentions RHEV 3.1, but I am using 3.4...

My colleague swears we don't - he has set it up on VMware and no you don't, but then RHEV is different than VMware...

There is a procedure it looks like to mount the LUN further down the doc under smartstate analysis on RHEVM 3.0

so I'm not sure if that's what I should be doing.

Any input on this appreciated as I am trying to use some quiet Thanksgiving time to move mo PoC forward!

Thanks!
Bill
