As mentioned in Configuring a Tape Coordinator Machine, a separate Tape Coordinator process is associated with each tape drive on a Tape Coordinator machine. Each Tape Coordinator has an associated port, or address. You must assign the port a TCID and use that number in any commands issued to the Tape Coordinator; bak commands that involve a tape drive have a -tcid option for this purpose. The Backup System identifies and contacts a Tape Coordinator by its TCID.
The Backup System can track a maximum of 1024 tape drives. Valid TCIDs are the integers from 0 to 1023. You do not have to assign the numbers in sequence, and you can skip numbers. The drive with the TCID of 0 is used by default. You can use the bak lshosts command to list the Tape Coordinators that have entries in the Backup Database.
Adding a Tape Coordinator describes the steps used to add a Tape Coordinator to an existing Tape Coordinator machine. The steps assume that you have already configured the Tape Coordinator machine to which the Tape Coordinator is to be added according to the instructions in Dump Hierarchies and Dump Levels. You use the bak addhost command to add an entry for a Tape Coordinator to the Backup Database.
Removing a Tape Coordinator describes the steps used to remove an existing Tape Coordinator. You use the bak rmhost command to remove an entry for a Tape Coordinator from the Backup Database.
Remember to edit the TapeConfig file accordingly when you add or remove a Tape Coordinator. The TapeConfig file defines the mapping between a Tape Coordinator and a tape drive on a Tape Coordinator machine.
