The response:
It is only possible to use the fmthard way if the disks are exactly the same
in geometry. It is possible to mirror unlike disks by creating the slices by
hand. The slices just have to be larger than those they are mirroring. It
was also suggested that I could redefine the geometry of the second disk
(too scary for me).

The question:
I have two very similar disks on an Ultra1. I want to mirror the boot disk
to the second using DiskSuite ->
# format
Searching for disks...done
AVAILABLE DISK SELECTIONS:
0. c0t0d0 <HP-4.26GBA80-LXP0-LXP0 cyl 5823 alt 2 hd 10 sec 143>
/sbus@1f,0/espdma@e,8400000/esp@e,8800000/sd@0,0
1. c0t1d0 <HP-4.26GBB80-0854-0854 cyl 5848 alt 2 hd 8 sec 178>
/sbus@1f,0/espdma@e,8400000/esp@e,8800000/sd@1,0
I am tring to copy the vtoc from the boot disk to the second disk. I am
getting the following error ->
# prtvtoc /dev/rdsk/c0t0d0s2 | fmthard -s - /dev/rdsk/c0t1d0s2
Partition 0 not aligned on cylinder boundary: " 0 2 00
1049620 7168590 8218209 /"
#
Do the two disk that you want to mirror have to be EXACTLY alike? How can I
get around this issue of different cylinder boundaries?
