Installation guide

The
options
for the rrestore command are the same as for the restore
command. See Section 11.4 for a description of the options.
To restore the ./working/file1 file onto the local directory on machine1
from a backup tape mounted on machine2 where the backup device
/dev/rmt0h is attached, enter the following command from machine1. The
name machine1 must be in the /.rhosts file of machine2 to allow access
from machine1 to machine2.
# rrestore -xf machine2:/dev/rmt0h ./working/file1
The rrestore command starts a remote server, /usr/sbin/rmt, on the
remote machine to access the storage medium. This process should be
transparent. Refer to the rmt
(8) reference page for more information. See
Section 11.4 for a description of the options to the rrestore command.
11.4.5 Restoring the root and /usr File Systems
This section describes a procedure for restoring the root and /usr file
systems. The root file system must be restored before you can restore the
/usr file system. If the /var directory is on a file system other than /usr,
repeat the steps in this section for restoring /var.
The procedure in this section requires that you have access to the most
recent dump files of your root and /usr file systems. You should use this
procedure only when a catastrophic error occurs on the system disk, such
as a disk crash or when an inadvertent deletion of either the root or /usr
file systems renders the system inoperative.
The following example assumes that you are restoring from level 0 dump
files and that you are using the text-based (or character cell) interface to
the task.
1. Load the installation software. For removable media such as tape or
CDROM, insert the media into the appropriate drive. For RIS
installations, verify that the inoperative system has been registered on
the RIS server. See Sharing Software on a Local Area Network for
details. If the dump file is located on a remote system, include the
hostname of the inoperative system in the /.rhosts file of the remote
system. For security reasons, be sure to delete the hostname from the
/.rhosts file after the restore operation has completed.
2. Boot the Tru64 UNIX software as described for your processor and
distribution media in the Installation Guide. If your system had a
graphical interface, the Installation Setup screen would be
displayed, rather than the following menu. However, in both cases you
would select the UNIX Shell option.
3. Select the UNIX Shell option at the prompt.
