I have a clustered shared volume hosted on a Equallogic 4000X array.  There are three Hyper-V 2008 R2 servers sharing this cluster.  I need to add space to the CSV, currently at 800 MB.  Would like to increase to 1500 MB.  Not sure of the best way to do this?  Help would be appreciated.

Go into the EqualLogic GUI and expand the volume. It will ask you if you want to take a snapshot, say yes. You shouldn't need it (I never have in the hundreds of times I have don this). You to cluster manager and look under CSV to find out which cluster node is managing the CSV. Go to run diskpart.exe on that node and type in
Rescan
List disk
Select disk x ( the number of the disk with the free space)
Select partition 1
Expand

That is it. You should see the new CSV size and free space immediately under cluster manager. This is a safe, online, during the day operation.

BTY, 1500 GB is a large volume that takes a huge amount of space to backup, snapshot, clone, etc. (Though thin clones should help a lot). You may want to consider adding a second CSV instead. I have also gone to the strategy of having a CSV that has no snapshots and isn't replicated. That CSV holds the VM configuration files, and more importantly the .bin files which hold a copy of VM memory; there is no reason to snapshot the bin files because they can't really be used for recovery. If you have lots of space this is less of an issue, but something to think about if you are trying to optimize usable capacity or replication.

I just got the nerve up to do this.  Not that I didn't believe this was going to work a-ok during working hours.  For some reason I envisioned a mushroom cloud after I pushed the enter button on Expand.

The suggestion got me close.  When I tried the solution given it failed.  You can take a look at the screenshot to get the error message.

I did some further research and found that instead of 'List disk' to use 'List Volume'.

The steps I followed;

DISKPART.EXE  (You should get the diskpart prompt)
RESCAN
LIST VOLUME  (Not disk in my case)
SELECT VOLUME x
EXPAND

This worked perfectly and all went well.  No mushroom clouds.  Thank you very much for the advise.
