</PRE>
|
|
<P><STRONG>Description</STRONG>
|
|
<P>The <B>backup addhost</B> command creates a Tape Coordinator entry in
|
|
the Backup Database. The entry records
|
|
<UL>
|
|
<P><LI>The host name of the Tape Coordinator machine where the Tape Coordinator
|
|
(<B>butc</B>) process runs, as specified with the <B>-tapehost</B>
|
|
argument.
|
|
<P><LI>The Tape Coordinator's port offset number, as specified with the
|
|
<B>-portoffset</B> argument. An entry for the port offset must also
|
|
appear in the <B>/usr/afs/backup/tapeconfig</B> file on the Tape
|
|
Coordinator machine, where it is mapped to a UNIX device name (for a tape
|
|
device) or pathname (for a backup data file).
|
|
</UL>
|
|
<P>Each Tape Coordinator must have its own port offset number, and the command
|
|
fails if a Backup Database entry already exists for the requested port offset
|
|
number. To display existing Tape Coordinator entries, use the
|
|
<B>backup listhosts</B> command.
|
|
<P><STRONG>Options</STRONG>
|
|
<DL>
|
|
<P><DT><B>-tapehost
|
|
</B><DD>Specifies the fully-qualified hostname of the machine for which to create
|
|
a Tape Coordinator entry in the Backup Database. The machine must have
|
|
an entry in either the cell's naming service (such as the Domain Name
|
|
Service) or the host file (<B>/etc/hosts</B> or equivalent) on the machine
|
|
where the command is issued.
|
|
<P><DT><B>-portoffset
|
|
</B><DD>Specifies the Tape Coordinator's port offset number. Provide
|
|
an integer from the range <B>0</B> through <B>58510</B>, or omit this
|
|
argument to use the default value of <B>0</B> (zero). The value
|
|
must match the port offset number recorded for the same combination of Tape
|
|
Coordinator and tape device or file in the
|
|
<B>/usr/afs/backup/tapeconfig</B> file on the Tape Coordinator machine
|
|
named by the <B>-tapehost</B> argument.
|
|
<P><DT><B>-localauth
|
|
</B><DD>Constructs a server ticket using a key from the local
|
|
<B>/usr/afs/etc/KeyFile</B> file. The <B>backup</B> command
|
|
interpreter presents it to the Backup Server, Volume Server and VL Server
|
|
during mutual authentication. Do not combine this flag with the
|
|
<B>-cell</B> argument. For more details, see the introductory
|
|
<B>backup</B> reference page.
|
|
<P><DT><B>-cell
|
|
</B><DD>Names the cell in which to run the command. Do not combine this
|
|
argument with the <B>-localauth</B> flag. For more details, see the
|
|
introductory <B>backup</B> reference page.
|
|
<P><DT><B>-help
|
|
</B><DD>Prints the online help for this command. All other valid options
|
|
are ignored.
|
|
</DL>
|
|
<P><STRONG>Examples</STRONG>
|
|
<P>The following command creates an entry in the Backup Database that assigns
|
|
port offset number 4 to a Tape Coordinator running on the machine
|
|
<B>backup1.abc.com</B>:
|
|
<PRE> % <B>backup addhost -tapehost backup1.abc.com -portoffset 4</B>
|
|
|
|
</PRE>
|
|
<P>The following command creates a Backup Database entry that assigns port
|
|
offset number 0 to a Tape Coordinator on the machine
|
|
<B>backup3.abc.com</B>:
|
|
<PRE> % <B>backup addhost backup3.abc.com</B>
|
|
|
|
</PRE>
|
|
<P><STRONG>Privilege Required</STRONG>
|
|
<P>The issuer must be listed in the <B>/usr/afs/etc/UserList</B> file on
|
|
every machine where the Backup Server is running, or must be logged onto a
|
|
server machine as the local superuser <B>root</B> if the
|
|
<B>-localauth</B> flag is included.
