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 IBMAFS 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
-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 bos(8).
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
Prints the online help for this command. All other valid options are
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).
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
