Setting up a Tape Coordinator machine consists of using bak commands to configure the Tape Coordinators for the machine. You must also create the TapeConfig file, which includes a line for each Tape Coordinator on the machine. Each line defines the
· Size of tapes used in the drive, in kilobyte, megabyte, or gigabyte units.
· End-of-file (EOF) mark size for the drive. EOF marks are placed between filesets on a tape. The size of the EOF mark can differ for each type of tape drive.
· Device name (for example, /dev/rst0) of the drive.
· Tape Coordinator ID (TCID) of the drive.
Each tape drive and its Tape Coordinator must be assigned a TCID in the range from 0 to 1023; the TCID must be unique in the Backup Database of the local cell. When assigning the TCID, you must define the ID number in the Backup Database with the bak addhost command; you must also include the TCID in the entry for the tape drive in the TapeConfig file on the local disk of the Tape Coordinator machine.
Perform the following tasks once, when you initially configure a Tape Coordinator machine:
1. Prepare the tape drives.
2. Create the TapeConfig file that defines the tape parameters for each drive.
3. Create an entry in the Backup Database for the Tape Coordinator for each drive.
The following topics describe the steps necessary to configure a machine as a Tape Coordinator machine. The instructions in Steps Required for a Client-Only Machine are required only if the machine to be configured as a Tape Coordinator machine is not a DFS server machine of some type (the machine must at least be a DCE client). The instructions in Steps Required for All Machines are required for any machine to be configured as a Tape Coordinator machine.
