Just copying does not make a disk a boot disk.
This needs a boot block to be added to the disk

Incase of a Solaris OS

type in the following
installboot /usr/platform/`uname -i`/lib/fs/ufs/bootblk /dev/rdsk/c1t0d0s0
(Example only)

Subject: problems mirroring a disk

i'm trying to use rsync to mirror my server boot volume to another
disk of the same size (120gb) on the same machine:

% sudo rsync -avxuH --delete --progress /./  /volumes/cbc.server2/

although all of the files from the source volume appear to copy to
the destination, if i try to boot from the destination volume the
system doesn't recognize it as a bootable disk.

anyone have any clues as to what i might be doing wrong?

thanx in advance
