Is there an upgrade path to GUID GPT in a 2003 Serve Cluster to overcome 2TB limit?

We have recently added a new disk array to a Windows Server 2003
Enterprise file server cluster. We chose this particular unit (IBM
DS4200) because it allowed us to exceed the previous 2TB disk
limitation when coupled with IBM's new Storage Manager 10.10 software.
After configuring a 9.5TB logical disk and presenting it to the OS,
the disk is initialized as a basic disk and I can only use the first
2TB's of it. After doing some research I discovered (1) Dynamic disks
cannot be used in a cluster environment (this is how the project was
initially proposed) and (2) the 2TB limitation (due to MBR) in 2003
clusters is overcome in Windows Server 2008 clusters by the use of
GUID (Global) Partition Table (GPT) which allow up to 16 exabyte
disks. So my question is: "is there a way to use GPT in a 2003
cluster?". If not, my "work around" will be to create a set of 2TB
disks and create mount points at certain share levels to create the
appearance of a single disk (and hope there is no need to store a
single file over 2TB in size on it).
Thanks in advance for any help you can provide.
Regards,
Sam
