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>] [-config <configuration file>] [-help]

DESCRIPTION

The backup addhost command creates a Tape Coordinator entry in the Backup Database. The entry records

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/yfs/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/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).

-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).

-config <configuration file>

Sets the location of the configuration file to be used. The default file is /etc/yfs/yfs-client.conf.

-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.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

PRIVILEGE REQUIRED

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
