Re: Connectin HPE 3PAR to Power 9 and able to IPL from it?

Thanks for the responses.

Where I was coming from was initially we were going to use storage on a
DS8886 SAN connected to one of our mainframes and a second DS8886 in our DR
site.

This Redbook

http://www.redbooks.ibm.com/abstracts/sg248887.html?Open

in section 11.7

describes how you can connect a Power server to DS8K SAN natively, using
VIOS NPIV or VIOS VSCSI and boot from it.

Then it says in 11.8.2 if you boot from the SAN you can take advantage of
the features of the DS8000 copy features and replicate a copy of the LUNS
to another site where another Power box is located and boot from that. So
clearly it takes care of license numbers, devices etc.

And replication can be real time which is great for DR.

But our situation changed and we're now looking at two different data
centers where we don't have DS8K SANs but HPE 3PAR and so I was wondering
if I could use the same process to support DR.

Or two VIOS on one SAN with two (FC/ETH/RAID CARD) of all. You save a lot
of money in disks, enclosure and licenses.

Tried this (boot replicated VIOS to other machine) with same hardware
(2*P7 boxes) and the result is not suitable
for DR purposes as you will run into lots of new devices due to serial
number (or maybe bus number) changes.

Better way is to have two VIOS on two SANs.

I have not tried to replicate the VIOS servers via the SAN but it

strikes me that this would not be a good idea. It seems unlikely to me

that

a replicated VIO server would be any level of happy at all if IPLed onto
another system. That said, I've not tried it either. Dang another thing
for the 'some day' list.....
