NAME

       bos_addhost - Adds a database server machine to the CellServDB file

SYNOPSIS

       bos addhost -server <machine name> -host <host name>+
           [-cell <cell name>] [-clone] [-noauth] [-localauth] [-help]

       bos addh -s <machine name> -ho <host name>+
           [-ce <cell name>] [-cl] [-n] [-l] [-he]

DESCRIPTION

       The bos addhost command adds an entry for each database server machine specified with the -host argument
       to the /etc/openafs/server/CellServDB file on the machine named by the -server argument.

CAUTIONS

       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 /etc/openafs/server/CellServDB file. The OpenAFS Quick
       Start Guide explains in more detail how to add and remove database server machines.

       It is best to maintain a one-to-one mapping between hostnames and IP addresses on a multihomed database
       server machine (this is actually the conventional configuration for any AFS machine). The BOS Server uses
       the gethostbyname() routine to obtain the IP address associated with the hostname specified by the -host
       argument. If there is more than one address, the BOS Server records in the CellServDB entry the one that
       appears first in the list of addresses returned by the routine. The routine possibly returns addresses in
       a different order on different machines, which can create inconsistency.

OPTIONS

       -server <machine name>
           Identifies  the  server  machine on which to change the /etc/openafs/server/CellServDB file. Identify
           the machine by IP address or its host name (either fully-qualified or abbreviated unambiguously). For
           details, see bos(8).

           In cells that use the Update Server to distribute the contents of the /etc/openafs/server  directory,
           it  is  conventional  to specify only the system control machine as a value for the -server argument.
           Otherwise, repeat the command for each file server machine. For further discussion, see bos(8).

       -host <host name>+
           Specifies the fully-qualified host name (such as "db1.example.com") of each database  server  machine
           to register in the CellServDB file.

       -cell <cell name>
           Names  the  cell  in which to run the command. Do not combine this argument with the -localauth flag.
           For more details, see bos(8).

       -clone
           Register the host given by -host as a non-voting clone site, which prevents the host from becoming  a
           sync-site. This is an advanced feature and should be used with caution.

       -noauth
           Assigns  the  unprivileged  identity  "anonymous"  to  the  issuer. Do not combine this flag with the
           -localauth flag. For more details, see bos(8).

       -localauth
           Constructs  a  server  ticket  using  a   key   from   the   local   /etc/openafs/server/KeyFile   or
           /etc/openafs/server/KeyFileExt  file.   The  bos  command  interpreter presents the ticket to the BOS
           Server during mutual authentication. Do not combine this flag with the -cell or -noauth options.  For
           more details, see bos(8).

       -help
           Prints the online help for this command. All other valid options are ignored.

EXAMPLES

       The  following  command  adds the database server machines "db2.example.com" and "db3.example.com" to the
       /etc/openafs/server/CellServDB file on the machine "fs1.example.com" (the system control machine).

          % bos addhost -server fs1.example.com -host db2.example.com db3.example.com

PRIVILEGE REQUIRED

       The issuer must be listed in the /etc/openafs/server/UserList file on the machine named  by  the  -server
       argument, or must be logged onto a server machine as the local superuser "root" if the -localauth flag is
       included.
