Re: Removing Luns from exchange server - upgrading MPIO drivers

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
