Implement proper synopsis wrapping for HTML generation. This was done in three pieces. First, add HTML-specific tags to the POD to mark the synopsis for HTML purposes so that we can apply style information to it. Second, update the style sheet to indent all lines except for the first in the synopsis section. Third, add the appropriate S<> tags around option and argument pairs so that we don't wrap between the option and its argument. Unfortunately, due to the <I<foo>> style that looks nicer for other reasons, we have to use the very verbose S<<< >>>. Oh well.

=head1 DESCRIPTION
|
|
|
|
The B<vos changeaddr> command removes a server entry from the Volume
|
|
Location Database (VLDB) when the B<-remove> flag is combined with the
|
|
B<-oldaddr> argument. There must be no VLDB entries that list the machine
|
|
as a site for any version of a volume (if necessary, use the B<vos move>
|
|
or B<vos remove> command to more or remove volumes). It is appropriate to
|
|
remove a VLDB server entry when removing the corresponding file server
|
|
machine from service; this is the only recommended use of the command.
|
|
|
|
To display all VLDB server entries, use the B<vos listaddrs> command.
|
|
|
|
=head1 CAUTIONS
|
|
|
|
Combining the command's B<-oldaddr> and B<-newaddr> arguments is no longer
|
|
the appropriate way to change the IP address registered for a file server
|
|
machine. Furthermore, if a machine is multihomed and its server entry
|
|
includes several addresses, then the address specified with the
|
|
B<-newaddr> argument replaces all of the addresses currently listed in the
|
|
server entry that includes the address specified by the B<-oldaddr>
|
|
argument. This effectively makes the machine single-homed with respect to
|
|
AFS operations, which is probably not the desired result.
|
|
|
|
The recommended method for changing the IP addresses in a server entry is
|
|
instead to restart the C<fs> process group (which includes the File
|
|
Server) after using the utilities provided by the operating system to
|
|
reconfigure the machine's network interfaces. For a description of how the
|
|
File Server constructs and registers a list of its network interfaces in
|
|
the VLDB, see L<sysid(5)>.
|
|
|
|
If, counter to recommended usage, the command is used to change the IP
|
|
address in a server entry, it does not also change the names of machine
|
|
entries in the Protection Database. Operations fail when they refer to a
|
|
protection group that has an obsolete IP address in it. Use the B<pts
|
|
rename> command to change the names of machine entries that correspond to
|
|
the addresses changed with this command. Changing the address of a
|
|
database server machine also requires updating the client and server
|
|
versions of the F<CellServDB> file on every machine.

|
=head1 OPTIONS
|
|
|
|
=over 4
|
|
|
|
=item B<-oldaddr> <I<original IP address>>
|
|
|
|
Specifies the IP address currently registered for the file server machine
|
|
in the VLDB server entry. If there are multiple addresses registered for a
|
|
multihomed machine, use any of them to identify the server entry.
|
|
|
|
=item B<-newaddr> <I<new IP address>>
|
|
|
|
Specifies the new IP address that replaces all currently registered
|
|
addresses.
|
|
|
|
=item B<-remove>
|
|
|
|
Removes from the VLDB the server entry that includes the address specified
|
|
by the B<-oldaddr> argument.
|
|
|
|
=item B<-cell> <I<cell name>>
|
|
|
|
Names the cell in which to run the command. Do not combine this argument
|
|
with the B<-localauth> flag. For more details, see L<vos(1)>.
|
|
|
|
=item B<-noauth>
|
|
|
|
Assigns the unprivileged identity C<anonymous> to the issuer. Do not
|
|
combine this flag with the B<-localauth> flag. For more details, see
|
|
L<vos(1)>.
|
|
|
|
=item B<-localauth>
|
|
|
|
Constructs a server ticket using a key from the local
|
|
F</usr/afs/etc/KeyFile> file. The B<vos> command interpreter presents it
|
|
to the Volume Server and Volume Location Server during mutual
|
|
authentication. Do not combine this flag with the B<-cell> argument or
|
|
B<-noauth> flag. For more details, see L<vos(1)>.
|
|
|
|
=item B<-verbose>
|
|
|
|
Produces on the standard output stream a detailed trace of the command's
|
|
execution. If this argument is omitted, only warnings and error messages
|
|
appear.
|
|
|
|
=item B<-help>
|
|
|
|
Prints the online help for this command. All other valid options are
|
|
ignored.
|
|

|
=head1 EXAMPLES
|
|
|
|
The following command removes the VLDB server entry that includes the IP
|
|
address C<192.12.107.214>.
|
|
|
|
% vos changeaddr -oldaddr 192.12.107.214 -remove
|
|
|
|
=head1 PRIVILEGE REQUIRED
|
|
|
|
Issuer must be listed in the F</usr/afs/etc/UserList> file on the machine
|
|
specified with the B<-oldaddr> argument and on each database server
|
|
machine.
