RE: [dm-devel] path priorities on Sun's 6140

Ok. So I just realized that if I want to try the new RDAC support, then
I have to install the new beta kernel as well. It includes the RDAC
hardware handler.

I'm under serious pressure to get my cluster up and running asap and I
don't think I want to be installing a bunch of beta packages onto my
production servers. Especially kernels.

Well, I'm pretty sure their competitor has it with SP1 :-)

So this might mean not exploring the RDAC solution. Redhat's docs say
that they support a Sun OpenStorage D280 and our Sun rep says the 6140
is essentially identical. If that's the case, what am I don't wrong?

If you don't have the RDAC hw handler you'll basically have to switch the
array to AVT mode. It works quite well, provided you don't boot the nodes
too often.

Cheers,
