Volume header --humberto, Tue, 24 Jun 2008 15:26:44 -0400 reply
I tried this with the Origin 300 disks and it failed to boot because it couldn't find the miniroot in the volume header. Here's how I copied the OS onto another disk:

  # dvhtool -v list

  Current contents:
          File name        Length     Block #
          sgilabel            512           2
          symmon          1616384           3
          sash             266752        3160

  # dvhtool -v get symmon symmon
  # ls -l
  total 3160
  -rw-r--r--    1 root     sys       1616384 Jun 12 19:36 symmon
  # dvhtool -v get sash sash

  # dvhhtool -v list /dev/rdsk/dks0d2vh

  Current contents:
          File name        Length     Block #
          sgilabel            512           2

  # dvhtool -v add sash sash /dev/rdsk/dks0d2vh
  # dvhtool -v add symmon symmon /dev/rdsk/dks0d2vh
