If there are no changed tape devices to discover, then the Oracle Secure Backup
Web tool displays a message similar to the following:
Info: beginning device discovery for host_name.
Info: no device configuration changes found for host_name
3.
Click OK to return to the Devices page. The list of tape devices now includes the
discovered tape devices.
Configuring an NDMP Copy-Enabled Virtual Tape Library
An NDMP copy-enabled virtual tape library (VTL) is a virtual tape library with an
embedded NDMP server and multiple access paths. The embedded NDMP server
allows offloading the I/O associated with volume duplication from the application
running on the media server to the VTL.
An NDMP copy-enabled virtual tape library (VTL) must be represented in Oracle
Secure Backup as a group of tape devices with multiple attach specifications. This
ensures that the inventory data coming through the multiple access paths is identical.
Two Oracle Secure Backup host objects must be created to represent the VTL. One
object must be associated with the media server to which the VTL is attached. The
other host object must be associated with the VTL's embedded NDMP server. Both
host objects must be assigned the media server role in Oracle Secure Backup.
One Oracle Secure Backup library device object with two attach specifications must be
created for the virtual library. One access path is through the media server to which
the VTL is attached. The other access path is through the embedded NDMP server.
An Oracle Secure Backup tape device object with two access paths must also be
created for each virtual drive contained within the virtual library. As in the virtual
library case, one access path is through the media server, and the other is through the
embedded NDMP server.
One Oracle Secure Backup library device object with a single attach specification must
be created for the physical library. The access path is through the VTL's embedded
NDMP server. An Oracle Secure Backup tape device object with a single attach
specification must also be created for each physical drive contained within the
physical library. As in the physical library case, the access path is through the VTL's
embedded NDMP server.
Here is an example of the
obtool
commands that would be used to configure an
NDMP copy-enabled VTL. Many of the options that would be specified in a real
environment have been omitted for clarity. Also, the device names shown are simply
placeholders that may differ from the actual names in a real environment.
Note:
Multiple media servers may be able to access the physical
library and its drives if they are all connected to a shared SAN. In this
case, the Oracle Secure Backup device objects for the physical library
and its drives must be created with multiple attach points.
