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 OpenAFS Quick
       Start Guide 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.
