bos_addhost - Adds a database server machine to the CellServDB file
bos addhost -server <machine name> -host <host name>+
[-cell <cell name>] [-noauth] [-localauth] [-help]
bos addh -s <machine name> -ho <host name>+
[-c <cell name>] [-n] [-l] [-he]
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.
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 IBM AFS Quick Beginnings
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.
-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.abc.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).
Assigns the unprivileged identity "anonymous" to the issuer. Do not
combine this flag with the -localauth flag. For more details, see
Constructs a server ticket using a key from the local
/etc/openafs/server/KeyFile 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).
Prints the online help for this command. All other valid options
The following command adds the database server machines "db2.abc.com"
and "db3.abc.com" to the /etc/openafs/server/CellServDB file on the
machine "fs1.abc.com" (the system control machine).
% bos addhost -server fs1.abc.com -host db2.abc.com db3.abc.com
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
