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?

Thanks
Erik
