Autochanger Installation

To use an autochanger for Backup storage management, you must first use the jb_config program to configure the autochanger and test the device driver software you installed. Follow the instructions in this section to configure and test the device driver software on a Backup server or storage node with a SCSI autochanger attached.

How to Configure an Autochanger

1. Become root on the Backup server.

2. Enter the jb_config command.

3. Backup displays the installation script.

Example: Configuring a SCSI Autochanger

The following example shows the required responses to configure a SCSI autochanger. The driver software detects and displays the information for all SCSI autochangers attached to the system.

# jb_config

When you use the jb_config program to configure an autochanger, Backup creates a new resource with the name you specified. You can view the new resource in the Jukeboxes resource in the Backup administration program. Refer to the online help or the nsr_jukebox(5) man page for details on the attributes of the Jukeboxes resource.

Enabling and Registering the Autochanger Software Module

After you install, configure, and test the autochanger, enter the enabler code for the Backup Autochanger Software Module according to the instructions on your enabler certificate. Be sure to register and authorize the Autochanger Software Module, or the software disables itself 45 days after you enter the enabler. See "Enabler Code Entry " for further information.

If you install additional autochangers later, you must enable and register each additional Autochanger Software Module you purchase as well as configure and test the driver software for the new autochanger. You only need to reinstall the Backup device drivers to add an additional autochanger if you removed the device driver software after the original installation.

Remote Autochanger Management

Autochangers that are connected to storage node machines require a few additional configuration and management steps.

You can control most operations on remote autochanger devices from the Backup administration program. But for some remote autochanger operations, for example, reset, you must use the nsrjb or jb_config commands on the storage node machine. You can issue the commands as root, either from the local machine or through a remote login session.

After you install the storage node binaries on the storage node machine, define the storage node's devices. The method for defining devices is described in "Remote Device Configuration ". An overview is provided here.

When you add a remote autochanger device, first add the storage node's hostname to the Administrator attribute in the NSR resource (Server window in the Backup administration program) in the following form:

root@storage-node-hostname

Then, run the jb_config program on the storage node machine (as shown in "Autochanger Installation") to define each device in the autochanger. See Appendix B, Command Line Reference Utilities or refer to the jb_config(1m) man page for the syntax and options for this program.

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/rmt/1mbn is a device called /dev/rmt/1mbn on a storage node machine called omega.
