change disks in a storageworks 5i array

I've got a DL380 G3 with 2 internal 36Gb disks in a single logical drive mirror using the internal storageworks 5i controller.
I would like to change these 2 36Gb disks for a pair of 18Gb disks. I cannot find a way to migrate the array to another pair of disks using any of the RAID migration/resizing options offereed by the controller.
These are the system disks and I have no great desire to reinstall the W2KAS OS.
Best option I can see so far is to create a second array and logical drive using the 18Gb disks and then use some third party utility to try and copy the contents of one drive to the other - made more awkward by the fact that most of these utilites want to operate outwith windows after a reboot (and hence have no drivers available to even see the logical disks being presented by the controller).
Furthermore I can only seem to get the DL360 to boot off the logical drive with the lowest number and I cannot seem to see how to rename or renumber a logical drive without deleting it and potentially then losing all the data on it.
All ideas gratefully received
thnx
