Each tape drive allocated to mvBase is assigned a logical tape unit number, and may be configured in two general ways:
Via the Tapes tab of the Administration Utility
Through commands executed at the TCL prompt
Two mvBase tape units are configured by default during installation:
Drive A, the Server’s floppy drive
The virtual tape device mapped to the virtual tape file that contains the initial mvBase database
Additional tape units may be allocated to mvBase subsequent to installation and before launching the Server. These assignments are usually made when the system is coldstarted (if they are specified in the USER-COLD-START Proc). They can also be overridden to allow a different physical tape drive to be a particular logical tape unit.
This topic describes the customary actions associated with tape unit configuration and removal. Use this topic to create or define mvBase tape units (tape devices which mvBase can use), or to remove such a tape unit from mvBase.
Once you have configured the desired mvBase tape unit(s), proceed to Using mvBase Tape Units for attaching, formatting and accessing these devices.
This section contains the following topics.
Perform this procedure to add or remove mvBase tape units. Such devices include physical drives, virtual tape files, virtual tape links, and remote floppy drives. Physical devices must be previously configured in Windows. |
|
Contains some additional explanation about remote floppy devices as applicable to the previous procedure. |
|
Perform this procedure to create temporary virtual tape units at TCL. The Server normally removes these tape units whenever the system is rebooted. |
|
This topic provides additional information and considerations pertaining to virtual tape links. |
|
Perform this procedure to define a virtual tape link independent of the Server tab (Administration Utility). |
