|
|
|
|
|
2005-12-13 19:21:13 +00:00
|
|
|
The B<backup addhost> command creates a Tape Coordinator entry in the
|
|
|
|
Backup Database. The entry records
|

|
|
=over 4
|
|
|
|
|

|
|
=item *
|
|
|
|
|
|
|
|
The host name of the Tape Coordinator machine where the Tape Coordinator
|
2005-12-13 19:21:13 +00:00
|
|
|
(B<butc>) process runs, as specified with the B<-tapehost> argument.

|
|
|
|
|
|
|
=item *
|
|
|
|
|
|
|
|
The Tape Coordinator's port offset number, as specified with the
|
2005-12-13 19:21:13 +00:00
|
|
|
B<-portoffset> argument. An entry for the port offset must also appear in
|
|
|
|
the F</usr/afs/backup/tapeconfig> file on the Tape Coordinator machine,
|
|
|
|
where it is mapped to a UNIX device name (for a tape device) or pathname
|
|
|
|
(for a backup data file).

|
|
|
Each Tape Coordinator must have its own port offset number, and the
|
|
|
|
command fails if a Backup Database entry already exists for the requested
|
|
|
|
port offset number. To display existing Tape Coordinator entries, use the
|
2005-12-08 12:14:33 +00:00
|
|
|
B<backup listhosts> command.

2005-12-08 12:14:33 +00:00
|
|
|
|
|
|
|
Specifies the fully-qualified hostname of the machine for which to create
|
2005-12-13 19:21:13 +00:00
|
|
|
a Tape Coordinator entry in the Backup Database. The machine must have an
|
|
|
|
entry in either the cell's naming service (such as the Domain Name
|
|
|
|
Service) or the host file (F</etc/hosts> or equivalent) on the machine
|
2005-12-08 12:14:33 +00:00
|
|
|
where the command is issued.

|
|
|
|
2005-12-13 19:21:13 +00:00
|
|
|
Specifies the Tape Coordinator's port offset number. Provide an integer
|
|
|
|
from the range C<0> through C<58510>, or omit this argument to use the
|
|
|
|
default value of C<0> (zero). The value must match the port offset number
|
|
|
|
recorded for the same combination of Tape Coordinator and tape device or
|
|
|
|
file in the F</usr/afs/backup/tapeconfig> file on the Tape Coordinator
|
|
|
|
machine named by the B<-tapehost> argument.

Constructs a server ticket using a key from the local
|
2005-12-13 19:21:13 +00:00
|
|
|
F</usr/afs/etc/KeyFile> file. The B<backup> command interpreter presents
|
|
|
|
it to the Backup Server, Volume Server and VL Server during mutual
|
|
|
|
authentication. Do not combine this flag with the B<-cell> argument. For
|
|
|
|
more details, see L<backup(8)>.
