anyone got any useful documents or tips on this? Need to move the Quorum on
a 4 node 64 bit cluster.

Easiest way would be to just add the new LUN to the cluster and then use
MSCS to move the quorum to a new drive. See

thanks john, I had stumbled on that one and yes it does look incredibly
easy. Worked a treat on my test system too.
One problem that i have is that my quorum drive also has msdtc using it, so
that procedure looks a bit of a mare (so I am going to have to do a two
phase process in order to retain original drive letter for that).
Thanks for your help.

I would break, uninstall, then reinstall MSTDC rahter than play the drive
letter rename game. Of course, that depends on the maintenance window you

We just upgraded our SAN and I have been doing exactly what you are trying on
all my SQL clusters. Goeff is right on about the MSDTC, I have always placed
it into its own cluster group; the easiest way to move it was break,
uninstall, reinstall using the new LUN. The quorum was easy as well, but you
have to do the process twice is you want to keep the same drive letter; that
is easy enough with cluadmin though (note your dependency structure so you
can rebuild them). We use Veritas SFW5.1, if you are interested in the exact
steps let me know and I can help with documentation.

yeah I agree with both of you.In the end I did the two phase approach last
What I did was:-
added in new disk resource across cluster
moved quorum to another existing disk resource
changed drive letter of old quorum/ dtc drive
changed drive letter of new disk resource to what old quorum letter was
did a robocopy of dtc directory with permissions to new resource.
offlined old disk resource
brought online dtc
moved quorum to new disk resource
failover testing/ tidied up
….not too bad really to be honest. Yes Geoff I’m sure I’ve attempted to
move DTC in the past to a lot of fustration and decided that it isnt worth
Jasen your point about the seperate cluster group is probably a good idea
(something which I have thought about before in fact) but this time was
easier to do a like for like swap.
Thanks for your comments.

Glad it worked for you! I migrated another one yesterday, works like a charm!
