Adding a virtual tape library to your environment

Define a virtual tape library (VTL) to take advantage of mount performance and scalability advantages.

About this task

VTLs are identified by using the DEFINE LIBRARY command and specifying the LIBTYPE=VTL parameter. Because a VTL library functionally interacts with the server in the same way that a SCSI library does,you can use the UPDATE LIBRARY command to change the library type of a SCSI library that is already defined. You do not have to redefine the library.

Procedure

  • Add a new VTL library. Define the library as a VTL to the server, as shown in the following example:
    define library chester libtype=vtl

    This sets up the new VTL library and enables the RELABELSCRATCH option to relabel volumes that have been deleted and returned to scratch status.

  • Update a SCSI library to a VTL.
    If you have a SCSI library and you want to change it to a VTL, use the UPDATE LIBRARY command to change the library type:
    update library calzone libtype=vtl
    You can issue this command only if the library that is being updated is defined with the LIBTYPE=SCSI parameter.
