controlling Backup server. The storage node runs special Backup software that
controls devices. The data stored on media in remote devices is tracked in the media
database and online client file indexes on the controlling Backup server.
Storage nodes you add to your Backup configuration can increase the Backup
server's performance, give you more flexibility in designing your network, and
centralize the control of data management activities to one or a few Backup servers.
To create a storage node, install the storage node binaries from the Backup software
distribution on the storage node machine. Then define the storage node's devices.
The method for defining devices is described in "Remote Device Configuration" on
page 60.
The storage node hostname does not need to be on the server's Administrator list
unless you run jb_configand scanneron the storage node. The entry for this is
root@storage_node_hostname.
For an autochanger or silo, you must manually add the storage node's hostname to
the Administrator list before you define the devices with the jb_configprogram.
When the jb_configprogram is completed, you can remove the storage node's
hostname from the Administrators list. If you need to configure a new autochanger
later, you must add the hostname before you run the jb_configprogram again.
After you add the storage node's hostname to the Administrator list, one instance of
nsrmmdstarts on the storage node for each device that it controls.
