NAME
bos_removehost - Removes a database server machine from the CellServDB
file
SYNOPSIS
bos removehost -server <machine name> -host <host name>+
[-cell <cell name>] [-noauth] [-localauth] [-help]
bos removeh -s <machine name> -ho <host name>+
[-c <cell name>] [-n] [-l] [-he]
DESCRIPTION
The bos removehost command removes the entry for each database server
machine specified with the -host argument from the
/etc/openafs/server/CellServDB file on the server 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 IBM AFS Quick Beginnings
explains in more detail how to add and remove database server machines.
OPTIONS
-server <machine name>
Indicates 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 "fs2.abc.com") of
each database server machine to remove from 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).
-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 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 removes the former database server machine
"db2.abc.com" from the CellServDB file on the system control machine
"fs1.abc.com".
% bos removehost -server fs1.abc.com -host db2.abc.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.
