Restarting ACSLS or NDMP Libraries

If an ACSLS or NDMP library encounters a network problem, use the following procedure to restart the library. The Restart method restarts the network and socket connections by removing them and adding the library again.

To restart an ACSLS or NDMP library:
1
In the Navigation pane, click Manage Devices.
2
In the list of devices, click the icon to locate the library, and then click the corresponding Manage Library icon .
3
On the Tape Library Management page, click Restart.
4
In the confirmation dialog box, click OK.

Importing shadow tapes (NetApp VTL)

The NetApp VTL Shadow Tape option allows you to quickly import a tape from the shadow tape pool whenever possible instead of obtaining the physical tape.

To use shadow tapes, you need to do the following:

•
Configure the Enable Shadow Tapes option on the filer and library containing the virtual tapes. For more information about enabling shadow tapes, consult the relevant NetApp VTL documentation.
•
Select barcodes as the default labels for virtual tapes in NetVault Backup. NetVault Backup requires this method of labeling media to be fully functional. You can use barcodes as default labels by selecting the Use Barcodes as Labels check box in the Media Manager settings dialog box. For more information, see Configuring general settings for Media Manager.

With shadow tapes enabled, whenever a virtual tape is exported to a physical tape, the virtual tape is moved to the shadow tape pool. The shadow tape pool is invisible to the backup application and it is not listed as part of a virtual library, but it is available for quick access if the physical tape is later imported. It is also available for reading if the physical tape is stored off-site or is otherwise unavailable.

The NetApp VTL manages the space used by shadow tapes. It can delete a shadow tape if more space is required for the new backup data. The administrator can set a preferred retention time for shadow tapes. If the retention period has not expired, the NetApp VTL sends a notification before deleting the shadow tape.

Note the following:

•
The media requests for shadow tapes can only be used for Restore or Duplication tasks as these tapes are converted to read-only virtual tapes.
•
No permanent records are created in the NetVault Database for shadow tape media. The database only stores the details of actual media. The shadow tape attribute is associated with the media when they are imported to the library as shadow tapes. Therefore, you must export all shadow media before stopping or restarting NetVault Backup. If you fail to export the media, they lose the shadow attribute and are converted to read-only items. For the same reason, you must export the shadow tapes before opening a library door.
•
Error messages are displayed if you try to import media when nothing is available in the shadow tape pool or when the shadow tapes option is not supported on the device.
To import virtual tapes:
1
In the Navigation pane, click Manage Devices.
2
In the list of devices, click the icon to locate the library, and then click the corresponding Manage Library icon .
3
On the Tape Library Management page, click Import Media.
4
In the Media Barcode list, select or type the barcode for the tapes that you want to import.
5
Click Import.
The requested tapes are imported to the medium changer from the shadow tape pool or physical library. When both shadow tapes and physical tapes are available, the shadow tapes are converted to read-only virtual tapes and imported to the entry/exit port. When only the physical tapes are available, virtual tapes are created from the physical tapes and imported to the entry/exit port.

Removing a tape library

You can use the following procedure to remove a tape library that is no longer required.

When you remove a tape library, it does not delete the media information from the NetVault Database. You can use the media on any other library that supports the media type. Scanning is not required if you use the media in the same NetVault Backup domain. In a different NetVault Backup Domain, you must scan the media to access the backups.

To remove a tape library:
1
In the Navigation pane, click Manage Devices.
2
In the list of devices, click the icon to locate the library, and then click the corresponding Manage Library icon .
3
On the Tape Library Management page, click Remove, and then in the confirmation dialog box, click OK.
