backup_addhost - Adds a Tape Coordinator entry to the Backup Database
backup addhost -tapehost <tape machine name> [-portoffset <TC port offset>] [-localauth] [-cell <cell name>] [-help] backup addh -t <tape machine name> [-p <TC port offset>] [-l] [-c <cell name>] [-h]
The backup addhost command creates a Tape Coordinator entry in the Backup Database. The entry records · The host name of the Tape Coordinator machine where the Tape Coordinator (butc) process runs, as specified with the -tapehost argument. · The Tape Coordinator's port offset number, as specified with the -portoffset argument. An entry for the port offset must also appear in the /var/lib/openafs/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 backup listhosts command.
-tapehost <tape machine name> Specifies the fully-qualified hostname of the machine for which to create 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 (/etc/hosts or equivalent) on the machine where the command is issued. -portoffset <TC port offset> Specifies the Tape Coordinator's port offset number. Provide an integer from the range 0 through 58510, or omit this argument to use the default value of 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 /var/lib/openafs/backup/tapeconfig file on the Tape Coordinator machine named by the -tapehost argument. -localauth Constructs a server ticket using a key from the local /etc/openafs/server/KeyFile 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). -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 backup(8). -help Prints the online help for this command. All other valid options are ignored.
The following command creates an entry in the Backup Database that assigns port offset number 4 to a Tape Coordinator running on the machine "backup1.example.com": % backup addhost -tapehost backup1.example.com -portoffset 4 The following command creates a Backup Database entry that assigns port offset number 0 to a Tape Coordinator on the machine "backup3.example.com": % backup addhost backup3.example.com
The issuer must be listed in the /etc/openafs/server/UserList file on every machine where the Backup Server is running, or must be logged onto a server machine as the local superuser "root" if the -localauth flag is included.
