Reduce size of RAID 5 virtual disk
I've got Windows Server 2003 installed on a PERC H700 RAID-5 virtual disk. Total disk size is 5.5 TB. The problem is that WinServer 2003 can't use all of the disk due to the 2TB MBR limit (and I can't convert to GPT without wiping out all of the partitions, which is what I'm trying to avoid). Since 3.5TB of disk space is unallocated (and unallocatable), is there a way of reducing the virtual disk size to remove this space that can't be used anyway? I could then using the remaining capacity to create a new virtual disk that can be set up as GPT and access the remaining space through it (or two new virtual disks 2TB and 1.5TB in size). I know you can expand a virtual disk, but can you shrink one?

No, you can expand most Virtual Disks, but you cannot shrink them.
You will need to start over on this, creating one VD smaller than 2TB for the OS/boot disk, then the remainder can be used in another VD.

That's what I was thinking (and would really like to avoid), but thought I would check before going through all that work.
