    <title>Description</title>
    <para>The <emphasis role="bold">fs newcell</emphasis> command removes the Cache Manager's kernel-resident list
    of database server machines for the cell specified by the <emphasis role="bold">-name</emphasis>
    argument and replaces it with the database server machines named by the
    <emphasis role="bold">-servers</emphasis> argument.</para>

    <para>Each time the machine reboots, the Cache Manager constructs the kernel
    list of cells and database server machines by reading the local
    <replaceable>/usr/vice/etc/CellServDB</replaceable> file. This command does not change the
    <replaceable>CellServDB</replaceable> file, so any changes made with it persist only until the
    next reboot, unless the issuer also edits the file. The output of the <emphasis role="bold">fs
    listcells</emphasis> command reflects changes made with this command, because that
    command consults the kernel-resident list rather than the <replaceable>CellServDB</replaceable>
    file.</para>

    <para>This command can introduce a completely new cell into the kernel-resident
    list, but cannot make a cell inaccessible (it is not possible to remove a
    cell's entry from the kernel-resident list by providing no values for the
    <emphasis role="bold">-server</emphasis> argument). To make a cell inaccessible, remove its entry from
    the <replaceable>CellServDB</replaceable> file and reboot the machine.</para>

    <para>If the <emphasis role="bold">-name</emphasis> argument names a DCE cell, then the <emphasis role="bold">-servers</emphasis> argument
    names DFS Fileset Location (FL) Server machines. The <emphasis role="bold">-linkedcell</emphasis>
    argument specifies the name of the AFS cell to link to a DCE cell for the
    purpose of DFS fileset location.  Refer to the <emphasis>IBM AFS/DFS Migration
    Toolkit Administration Guide and Reference</emphasis> for more information on
    linking AFS clients to DCE cells using this command or by editing the
    <replaceable>/usr/vice/etc/CellServDB</replaceable> file.</para>

  <refsect1>
    <title>Cautions</title>
    <para>Some commands, such as the <emphasis role="bold">klog</emphasis> command, work correctly only when the
    information is accurate for a cell in both the <replaceable>CellServDB</replaceable> file and the
    kernel-resident list.</para>

    <title>Examples</title>
    <para>The following example changes the machine's kernel-resident list of
    database server machines for the ABC Corporation cell to include the
    machines <computeroutput>db1.abc.com</computeroutput> and <computeroutput>db2.abc.com</computeroutput>:</para>

<programlisting>
   % fs newcell -name abc.com -servers db1.abc.com db2.abc.com

</programlisting>
      <para>The following example links the DCE cell <computeroutput>dce.abc.com</computeroutput> to the AFS cell
      <computeroutput>abc.com</computeroutput>. The AFS client contacts the Fileset Location (FL) servers
      <computeroutput>db1.dce.abc.com</computeroutput> and <computeroutput>db2.dce.abc.com</computeroutput> for fileset location information
      as it interprets a DFS pathname.</para>

<programlisting>
   % fs newcell -name dce.abc.com \
       -servers db1.dce.abc.com db2.dce.abc.com \
       -linkedcell abc.com
