NAME

       backup_addhost - Adds a Tape Coordinator entry to the Backup Database

SYNOPSIS

       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]

DESCRIPTION

       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.

OPTIONS

       -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.

EXAMPLES

       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.abc.com":

          % backup addhost -tapehost backup1.abc.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.abc.com":

          % backup addhost backup3.abc.com

PRIVILEGE REQUIRED

       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.
