It *may* work, but be forwarned-- I've tried to swap root disks between
an Ultra1 and a 170E and did a "boot -r" from the OK prompt. No dice--
since both systems have different SCSI controllers it didn't make the
links correctly for the root device.

Since the Blade100 and the AXi (AXe?) boards are similar (IDE
controllers, etc) it may just work. Although it may take a lot more
time, you'd be better off doing:

1) format/newfs of the drives at home and partition them out the way you want
2) "install" the disk you want as the new root disk in the place of the 2nd
disk on the AXe board (master on 2ndary channel.) Then use ufsdump piped to
ufsrestore to move files from one drive to the next.
3) Play musical disks so you can do the same to move partitions from the 2nd
disk to your other 2nd disk (or whatever you had in mind if you wanted to
relayout the partitions.)
4) Boot off the new disks and check everything out
5) patch the hell out of the "new" w/ MU4, Recommended, etc. Skip the 4/01
CDs.
