#
# This script was developed to speed install times and reduce errors
# of 2 drive systems being loaded with jumpstart that required
# mirrored boot disks. It has been used extensively on Solaris 2.6, 7, 8,
# and 9 with minimal testing on betas of 10. Use at your own risk
# and make sure you have a backup first. No warranty express or implied.
#
# This script will setup disksuite to mirror one drive to another and
# setup boot aliases for them. rootdisk will be mirrored to mirrordisk.
# Slice 7 of the disk named in rootdisk will be used for the metadb
# and the slice must already exist. Disksuite must already be installed.
# A script is created and linked to /etc/rc3.d/S99md-setrootenv that
# runs after the reboot and then deletes its link. Please change
# the rootdisk, mirrordisk, and slices to get mirrored before running
# to match your system.
