Re: A/P cluster rebuild or change

I meant to say "you do NOT benefit from the processor if you run an x86 OS
on a 64 bit processor"

Well, you should stay on the same version of Windows really, this in
regards
to processor architecture.

So, if your old nodes are running Windows 2003 EE x86, then your new nodes
should run the same OS !

(you can run W2K3-EE-x86 on an x64 or AMD64 processor, you just benefit
from
that, it is still a 32 bit OS in the end, running 32 bit applications)

Good Luck with your cluster,
Rgds,
Edwin.

Thanks. I am sort of leaning towards the adding two nodes then removing
the
original older ones. As far as the processors you are just meaning I
can't
go from a X86 to any 64 bit processor right. I would like to increase
processor speed and possibly more of them would that be an issue?
Thanks
again Edwin!!

OK, here is the scenario. We have a two node A/P cluster on Win
2003
and
an
exchange 2003 virtual which is our corproate email so it can't go
down.
One
of the nodes has just really gone in the tank so I wanted to evict
the
node
and then just format and rebuild, then re join to the cluster. Does
this
sound to easy and / or what should I look out for?

Yes, this is the way to do it


Would it be possible to get two more new servers which of course
would
have
different hardware and processors and then add them to the current
cluster,
make sure all the disks are seen the same as the existing nodes and
migrate
the virtual exchange to one of these nodes and then evict the two
original
nodes?

Yes, you can do that, you would briefly run a 3 or 4 node cluster when
you
have the new nodes added, but not yet removed the old nodes. You have
to
remove the old nodes, in order to end up with a 2 node cluster on the
same
hardware. Please ensure that your new servers and old SAN/fabric
combination
are still in the HCL as a fully supported cluster solution, so you end
up
with 2 new nodes on a cluster, which is fully supported.

The issue being in this scenario the hardware would be different
than
the current two nodes as we can't get the same servers.

the only thing to watch out for is that you do not mix processor
architecture. if your old nodes are running x86 then you can NOT mix
this
with x64 or IA64, as the binaries/executables are different, that will
not
work.


Again, any input on what might be the best and safest way to proceed
with
getting the cluster back to top shape would be appreciated!!
Thanks!
