|
<P><STRONG>Description</STRONG>
|
|
<P>The <B>bos removehost</B> command removes the entry for each database
|
|
server machine specified with the <B>-host</B> argument from the
|
|
<B>/usr/afs/etc/CellServDB</B> file on the server machine named by the
|
|
<B>-server</B> argument.
|
|
<P><STRONG>Cautions</STRONG>
|
|
<P>After executing this command (and waiting for the Update Server to
|
|
propagate the changes, if it is used), restart the database server processes
|
|
on all database server machines to force election of a quorum that includes
|
|
the new set of machines listed in the <B>/usr/afs/etc/CellServDB</B>
|
|
file. The <I>IBM AFS Quick Beginnings</I> explains in more detail
|
|
how to add and remove database server machines.
|
|
<P><STRONG>Options</STRONG>
|
|
<DL>
|
|
<P><DT><B><B>-server</B>
|
|
</B><DD>Indicates the server machine on which to change the
|
|
<B>/usr/afs/etc/CellServDB</B> file. Identify the machine by IP
|
|
address or its host name (either fully-qualified or abbreviated
|
|
unambiguously). For details, see the introductory reference page for
|
|
the <B>bos</B> command suite.
|
|
<P>In cells that run the United States edition of AFS and use the Update
|
|
Server to distribute the contents of the <B>/usr/afs/etc</B> directory, it
|
|
is conventional to specify only the system control machine as a value for the
|
|
<B>-server</B> argument. In cells that run the international
|
|
version of AFS, repeat the command for each file server machine. For
|
|
further discussion, see the introductory reference page for the <B>bos</B>
|
|
command suite.
|
|
<P><DT><B><B>-host</B>
|
|
</B><DD>Specifies the fully-qualified host name (such as
|
|
<B>fs2.abc.com</B>) of each database server machine to
|
|
remove from the <B>CellServDB</B> file.
|
|
<P><DT><B><B>-cell</B>
|
|
</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>bos</B> reference page.
|
|
<P><DT><B><B>-noauth</B>
|
|
</B><DD>Assigns the unprivileged identity <B>anonymous</B> to the
|
|
issuer. Do not combine this flag with the <B>-localauth</B>
|
|
flag. For more details, see the introductory <B>bos</B> reference
|
|
page.
|
|
<P><DT><B><B>-localauth</B>
|
|
</B><DD>Constructs a server ticket using a key from the local
|
|
<B>/usr/afs/etc/KeyFile</B> file. The <B>bos</B> command
|
|
interpreter presents the ticket to the BOS Server during mutual
|
|
authentication. Do not combine this flag with the <B>-cell</B> or
|
|
<B>-noauth</B> options. For more details, see the introductory
|
|
<B>bos</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 removes the former database server machine
|
|
<B>db2.abc.com</B> from the <B>CellServDB</B> file on
|
|
the system control machine <B>fs1.abc.com</B>.
|
|
<PRE> % <B>bos removehost -server fs1.abc.com -host db2.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
|
|
the machine named by the <B>-server</B> argument, or must be logged onto a
|
|
server machine as the local superuser <B>root</B> if the
|
|
<B>-localauth</B> flag is included.
