[gpfsug-discuss] 4.1.1 protocol support

[Bob Oesterlin]

Hi Simon

I was part of a beta program for GPFS (ok, better start saying Spectrum
Scale!) 4.1.1, so I've had some experience with the toolkit that installs
the protocol nodes. The new protocol nodes MUST be RH7, so it's going to be
a bit more of an involved process to migrate to this level than in the
past. The GPFS server nodes/client nodes can remain at RH6 is needed.

Overall it works pretty well. You do have the option of doing things
manually as well. The guide that describes it is pretty good. If you want
to discuss the process in detail, I'd be happy to do so - a bit too much to
cover over a mailing list.
