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.
