Chapter 3: Configuration

When you add a remote autochanger device:
1. Add the storage node’s hostname to the Administrator attribute in the NSR
resource (Server window in the NetWorker Administrator program) in the
following form:
manager.sys@storage-node-hostname
2. Run the JBCONFIG program on the storage node machine to define each device
in the autochanger. Refer to “Appendix B: Command Line Reference” of the Legato
NetWorker Administrator’s Guide, UNIX Version, or refer to the jbexercise(1m) man
page for additional information on the command options available for the JBEXER
command.
The device names for remote devices begin with a prefix of “rd=” and the name of
the storage node machine. For example, rd=omega:/dev/tape31 is a device called
/dev/tape31 on a storage node machine called omega.
Autochanger Configuration and Management
After you install and test your autochanger on a storage node machine, use the
instructions in this section to manage the devices and media in your autochangers.
Adding More Autochanger Devices
To add more devices to an autochanger:
1. Define the new devices in the Devices resource so the NetWorker storage node
recognizes the added devices.
2. Enter the pathnames for the autochanger devices in the Jukeboxes resource so
NetWorker recognizes that the new devices belong to the autochanger.
Important: After you add a device pathname to the Devices resource, you must also
add it to the Devices field in the Jukeboxes resource. NetWorker associates the device
in the autochanger with the autochanger name. Refer to the NetWorker online help for
a description of the Devices resource and how to use it.
If an autochanger has more than one device, first list the device pathnames in the same
order as their physical location in the autochanger. If you are unsure of their order, refer
to the autochanger hardware manual or refer to the HP MPE documentation.
Auto Media Management with Autochanger Devices
The auto media management feature further automates the backup procedure. It frees
you from the task of prelabeling volumes before backup. When you enable the auto
media management attribute in the Jukeboxes resource, NetWorker assumes that the
volumes loaded in the autochanger can be handled exclusively as NetWorker media.
Backup volumes that appear unlabeled are considered blank and are automatically
labeled, mounted, and overwritten with new data. NetWorker only uses volumes that
it considers unlabeled if it cannot locate a writable volume or a volume ready for
recycling.
