  19 =head1 DESCRIPTION
  20
  21 The B<bos removehost> command removes the entry for each database server
  22 machine specified with the B<-host> argument from the
  23 F</usr/afs/etc/CellServDB> file on the server machine named by the
  24 B<-server> argument.
  25
  26 =head1 CAUTIONS
  27
  28 After executing this command (and waiting for the Update Server to
  29 propagate the changes, if it is used), restart the database server
  30 processes on all database server machines to force election of a quorum
  31 that includes the new set of machines listed in the
  32 F</usr/afs/etc/CellServDB> file. The I<OpenAFS Quick Start Guide> explains
  33 in more detail how to add and remove database server machines.
  34
  35 =head1 OPTIONS
  36
  37 =over 4
  38
  39 =item B<-server> <I<machine name>>
  40
  41 Indicates the server machine on which to change the
  42 F</usr/afs/etc/CellServDB> file. Identify the machine by IP address or its
  43 host name (either fully-qualified or abbreviated unambiguously). For
  44 details, see L<bos(8)>.
  45
  46 In cells that use the Update Server to distribute the contents of the
  47 F</usr/afs/etc> directory, it is conventional to specify only the system
  48 control machine as a value for the B<-server> argument. Otherwise, repeat
  49 the command for each file server machine. For further discussion, see
  50 L<bos(8)>.
  51
  52 =item B<-host> <I<host name>>+
  53
  54 Specifies the fully-qualified host name (such as C<fs2.example.com>) of each
  55 database server machine to remove from the B<CellServDB> file.
  56
  57 =item B<-cell> <I<cell name>>
  58
  59 Names the cell in which to run the command. Do not combine this argument
  60 with the B<-localauth> flag. For more details, see L<bos(8)>.
  61
  62 =item B<-noauth>
  63
  64 Assigns the unprivileged identity C<anonymous> to the issuer. Do not
  65 combine this flag with the B<-localauth> flag. For more details, see
  66 L<bos(8)>.
  67
  68 =item B<-localauth>
  69
  70 Constructs a server ticket using a key from the local
  71 F</usr/afs/etc/KeyFile> or F</usr/afs/etc/KeyFileExt> file.
  72 The B<bos> command interpreter presents the
  73 ticket to the BOS Server during mutual authentication. Do not combine this
  74 flag with the B<-cell> or B<-noauth> options. For more details, see
  75 L<bos(8)>.
  76
  77 =item B<-help>
  78
  79 Prints the online help for this command. All other valid options are
  80 ignored.

  84 =head1 EXAMPLES
  85
  86 The following command removes the former database server machine
  87 C<db2.example.com> from the F<CellServDB> file on the system control machine
  88 C<fs1.example.com>.
  89
  90    % bos removehost -server fs1.example.com -host db2.example.com
  91
  92 =head1 PRIVILEGE REQUIRED
  93
  94 The issuer must be listed in the F</usr/afs/etc/UserList> file on the
  95 machine named by the B<-server> argument, or must be logged onto a server
  96 machine as the local superuser C<root> if the B<-localauth> flag is
  97 included.
