bootable system disk from mirror

[youdaman]

I dd'ed my system disk to another drive on the same system. I partioned the new disk exactly to the system disk. When I try to boot off of the new disk, I get and error saying that it cannot boot the drive. I only dd'ed s0. I also mounted the drive to /mnt and did df -k and it is exactly the same as the original system disk. Is there an install boot block command I could use to copy the boot block over to the mirrored disk? Any help would be greatly appreciated!!!!

Hello , probably the solution is:

SCSI disk 1 ---> your first boot disk (Function OK)
SCSI disk 2 ---> your second boot disk (No function)

Each disk have a volume header block (partition 8), and the device used is for example :

/dev/rdsk/dks0d1vh

If you use the command "dvhtool /dev/rdsk/dks0d1vh" , select "vd" and "l" , print out the volume header, is very important that you have the same volume header in boot disks, in this case you can copy the header of first disk on the second.

See on-line documentation for command syntax .

Please , sorry for my english, i'm italian .
