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.
