Private LAN Dual Pathing

The private LAN on the VLS12000 has dual pathing which consists of a cable from each switch to
each node. If a LAN switch or a path to a LAN switch fails, the data transfer will automatically fail-over
to the other available switch.
• The primary path is through NIC 2 of the switch and is referred to in the error notification as eth1.
If the LAN switch associated with NIC2 fails, the Notifications tab will display all eth1 failures.
• The secondary path is through the USB LAN cable and is identified as eth2 in the error notification.
If the LAN switch associated with the USB LAN cable fails, the Notifications tab will display all
eth2 failures.
• If both paths fail, the critical alert will identify bond 0 as the combined failed path. If both paths
from the private LAN to a secondary node fails, the node is off-line; but if both paths to a primary
node fails, the whole device is off-line.
When a failure occurs, repair the failure. In most cases, the system will automatically recognize that
the repair is complete and restore the path or paths without having to reboot the system; however,
you may need to reboot the system if the repair includes installing a new USB LAN adapter.

Managing Cartridges

You can change the following parameters for existing cartridges from the Cartridge Parameters
window:
• Library with which they are associated
• Capacity
• Write access

Unloading a Cartridge from a Drive

If a tape becomes stuck in a drive and cannot be removed using the backup application, unload the
tape using Command View VLS:
1. Select the tape drive from the navigation tree
2. From the task bar, select Force Unload.
This will return the tape to its original slot.
NOTE:
Upon reboot of the VLS or restart emulations, all cartridges that were in drives will NOT be returned
to their original slots. They will be loaded back into the drives. Use Force Unload to return them to
their original slots if needed.

Freeing up Storage Space

Storage space can be freed up by erasing the data on or destroying virtual media that is no longer
used, such as:
• Cartridges that are no longer used by a backup application
