|
|
|
The B<backup listhosts> command displays the Backup Database record of the
|
|
|
|
port offset numbers defined for Tape Coordinator machines. A Tape
|
|
|
|
Coordinator must have an entry in the list to be available for backup
|
2005-12-08 12:14:33 +00:00
|
|
|
operations.
|
|
|
|
|
|
|
|
The existence of an entry does not necessarily indicate that the Tape
|
2005-12-13 19:21:13 +00:00
|
|
|
Coordinator process (B<butc>) is currently running at that port offset. To
|
|
|
|
check, issue the B<backup status> command.

|
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)>.

After a C<Tape hosts:> header, the output reports two things about each
|
|
|
|
Tape Coordinator currently defined in the Backup Database:

2005-12-13 19:21:13 +00:00
|
|
|
The hostname of the machine housing the Tape Coordinator. The format of
|
|
|
|
this name depends on the hostname format used when the B<backup addhost>
|
|
|
|
command was issued.

|
|
|
|
