8) After the HDD restore is complete, shutdown the DVEVM:
EVM # halt
9) When the "Power down" message is printed in the terminal window,

A.8.3.2 Restoring From Host Linux Workstation File System
This section assumes that you have installed the DVEVM software to the
host Linux /workdir/filesys/restore directory. After an NFS mount, this is
equivalent to /restore for the target DVEVM.
Follow these steps to restore the HDD from the host Linux workstation
restore directory:
1) Login to the DVEVM as root.
2) Go to the /restore directory.
EVM # cd /restore
3) Set the Linux date variable to today's date. If the date is too far off,
the target file system installation generates a bunch of warnings.
EVM # date MMDDHHMMCCYY
For example, for 9:00 am on April 18th, 2006, enter 041809002006.
4) Add execute permissions on the restore-hdd script.
EVM # chmod +x restore-hdd
5) Run the script in the /restore directory.
EVM # ./restore-hdd
6) The script will ask for confirmation: "This will destroy all data on
/dev/hda1 - are you sure?" Type yes .
7) After the HDD restore is complete, shutdown the DVEVM:
EVM # halt
8) When the "Power down" message is printed in the terminal window,
it is safe to power down the DVEVM.
9) Restart the DVEVM and configure U-Boot to root mount via the local
HDD. Follow the steps in Section A.5.1, Booting from Flash Using
