backup_delhost - Deletes a Tape Coordinator entry from the Backup Database
backup delhost -tapehost <tape machine name> [-portoffset <TC port offset>] [-localauth] [-butc_noauth] [-cell <cell name>] [-config <configuration file>] [-help]
The backup delhost command deletes the indicated Tape Coordinator entry from the Backup Database. It is then impossible to submit backup operations to that Tape Coordinator, even if it is still running. To keep configuration information consistent, also remove the corresponding entry from the /var/yfs/backup/tapeconfig file on the Tape Coordinator machine.
To list the Tape Coordinator machines and port offsets defined in the Backup Database, issue the backup listhosts command.
Specifies the hostname of the machine housing the Tape Coordinator to delete.
Specifies the port offset number of the Tape Coordinator to delete.
it defaults to
it is an integer between
0 (zero) and
and must match the port offset number assigned to the same combination of Tape Coordinator and tape device or file in the /var/yfs/backup/tapeconfig file on the Tape Coordinator machine indicated by the -tapehost argument.
Constructs a server ticket using a key from the local /etc/yfs/server/KeyFileExt file. The backup command interpreter presents it to the Backup Server, Volume Server and VL Server during mutual authentication. Do not combine this flag with the -cell argument. For more details, see backup(8).
Assigns the unprivileged identity
anonymous to the issuer for all connections to Tape Controllers butc.
This option should only be used when the Tape Controller is incapable of authenticated connections.
Names the cell in which to run the command. Do not combine this argument with the -localauth flag. For more details, see backup(8).
Sets the location of the configuration file to be used. The default file is /etc/yfs/yfs-client.conf.
Prints the online help for this command. All other valid options are ignored.
The following command deletes the Backup Database entry for the Tape Coordinator with port offset 2 on the Tape Coordinator machine
% backup delhost -tapehost backup3.example.com -portoffset 2
The issuer must be listed in the /etc/yfs/server/UserListExt file on every machine where the Backup Server is running, or must be logged onto a server with an account capable of reading the /etc/yfs/server/KeyFileExt file if the -localauth flag is included. =head1 SEE ALSO
