As Tim said we have grown LUNs on the SAN side and then just extended the LUN
with Diskpart, no outage or downtime or data loss, literally take seconds to
extend the LUN on the Windows side. If your SAN cannot accomadate growing
the existing LUNs maybe your SAN group can use BCV's to give you new bigger
LUNs. BCV's, Business Conitunuous Volume, on EMC storage, this is where the
SAN group creates a new larger LUN on the SAN and syncs the data to the new
LUN and points the server to the new LUN, again, no outage. we have never
done this on the cluster nodes but have done it many times on stand alone
Windows servers.

extend it on the server. No data loss and we don't have to copy the data
from one disk to another. I'd talk to my SAN provider and find out if that's
a possibility in your case. Depending on the SAN we'd either add bigger
drives or grow the virtual disks.
DiskPart is built into windows 2003, and other then not being able to extend
the boot disk, or a partitioned section of a disk that doesn't have
contiguous free space it works well for us. (There are other tools available
if you need to extend the boot disk for some reason).

I have 3 SAN attached LUNS Disk X: Disk U: and Disk W: that are used by
clustered servers. What is the proper procedure to migrate the data on
these
disks to new larger disks keeping the same drive letters and cluster
resources for these disks?
Are there any Microsoft step by step procedures?
This is a two server (Windows 2003 Servers) cluster.
This is critical data so I want to be sure we use the right procedures to
do
this so when we are done the application sees everything as before the
migration except the data is running on the new larger disks.
