Hi ,everybody.
It's long time sice I came here at last time, I hope following script will be useful to everyone.
--------------------------------------------------------------------------
#!/bin/sh
# program to copy root & usr partitions and create a new bootable disk
# Note that this script is limited to SCSI drives, and only those
# on controller 0.
# It makes the root & usr filesystem on partition 0 for target drive
# and install sash, ide & fx in the volume header of the target drive.
# usage ./clone_disk 0 1 0 2
echo '---------------------------------------------------------------------'
echo 'Note: This utility will create a bootable clone of the system disk '
echo 'on target disk and will build the target disk with an XFS filesystem.'
echo '---------------------------------------------------------------------'
