moving HSG80 disk to HSG60

Hi All,

We have a DS10 connected to a HSG80 and need to move the disks to
a HSG60. There are no other disks on the system, and we are booting
TRU64 5.1 from the HSG80. In other cases we were able to move RAID
and Mirror sets over by just physically moving the disks, re-creating
the RAID or Mirror set, and associating a unit with it without
initializing the RAID set. Unfortunately, the current RAID set is
divided into 4 logical units, and the HSG60 won't let us create the
partitions without initializing. Is there any way to move the disks
without having to save everything to tape, move the disks, boot from
CD and restore? The specifics of the HSG configuration are below.
