=head1 DESCRIPTION The B command adds an entry for each database server machine specified with the B<-host> argument to the F file on the machine named by the B<-server> argument. =head1 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 F file. The I 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 B<-host> argument. If there is more than one address, the BOS Server records in the F 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. =head1 OPTIONS =over 4 =item B<-server> > Identifies the server machine on which to change the F file. Identify the machine by IP address or its host name (either fully-qualified or abbreviated unambiguously). For details, see L. In cells that use the Update Server to distribute the contents of the F directory, it is conventional to specify only the system control machine as a value for the B<-server> argument. Otherwise, repeat the command for each file server machine. For further discussion, see L. =item B<-host> >+ Specifies the fully-qualified host name (such as C) of each database server machine to register in the F file. =item B<-cell> > Names the cell in which to run the command. Do not combine this argument with the B<-localauth> flag. For more details, see L. =item B<-clone> Register the host given by B<-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. =item B<-noauth> Assigns the unprivileged identity C to the issuer. Do not combine this flag with the B<-localauth> flag. For more details, see L. =item B<-localauth> Constructs a server ticket using a key from the local F file. The B command interpreter presents the ticket to the BOS Server during mutual authentication. Do not combine this flag with the B<-cell> or B<-noauth> options. For more details, see L. =item B<-help> Prints the online help for this command. All other valid options are ignored. =back =head1 EXAMPLES The following command adds the database server machines C and C to the F file on the machine C (the system control machine). % bos addhost -server fs1.example.com -host db2.example.com db3.example.com =head1 PRIVILEGE REQUIRED The issuer must be listed in the F file on the machine named by the B<-server> argument, or must be logged onto a server machine as the local superuser C if the B<-localauth> flag is included. =head1 SEE ALSO L, L, L, L, L, L The I at L. =head1 COPYRIGHT IBM Corporation 2000.
