Under VMS, on an HSG80, can Raid Partition Size be Increased?

I want to increase the size of one of the partitions in a raid 5 set on
an HSG80.

Current config:

NPCtop> show r3

I want to move d101 to another raid set, destroy it's partition (1) on
r3, and double the size of d109. Can I do this?

I didn't see any replies so here's my 2 centz! Once it's set you can
INcrease it but not DEcrease the size of the RAID. Somebody may know of a
commercial product that will accomodate you but why not just copy the data
off, create what you need then restore?
