Re: Removing Luns from exchange server - upgrading MPIO drivers

I would suggest screaming bloody murder if you don't get somebody more
helpful. While MPIO may be a Microsoft written and supported app, HP tells
you what the configuration is supposed to be in order to be supported.

There should be more support from HP else they should stop their whining
about how those EVA's get configured :)

Funny you should mention that, as that is what i thought as well. Imagine
my
surprise when HP support told me that MPIO drivers are a Microsoft
product,
and that although HP does write DSM's to work with Microsoft's MPIO
drivers,
that HP does NOT support them, i would have to go to Microsoft. Ugg - I
think i'll try them again and talk to a different technician. He was not
the
most helpful hp tech i've spoken with.

Thank you for your response.

Last I checked, EVA's were supported by HP and they were somewhat touchy
about the way they were supported and who does what on them. I HIGHLY
suggest you contact them prior to doing such a thing. I do realize that
you
own it, but it's best to exercise the HP/customer relationship in this
case.

Hello,

We have an exchange 2003 server (hp DL380), connected via FC to an HP
EVA
6000, with 2 luns, one for db and one for logs.

We need to upgrade our windows MPIO drivers on the exchange server in
order
to upgrade a piece of our san management tools.

Is there a best practice for this process? I'm thinking of stopping
and
disabling exchange services, unpresenting the LUNS, upgrading MPIO
drivers,
rebooting the exchange server, re-presenting the LUNS, and restarting
exchange.

Have i overlooked any gotcha's in this process? Do i have to unpresent
my
luns in order to upgrade my MPIO drivers?

We have to do this for our SQL servers as well, so if you have any info
on
that, it would be appreciated.

Thanks!
JR
