Options
 
Table 39. nvloadmedia

nvmakemedia

Description

Increases the capacity of a Virtual Tape Library (VTL) by creating additional media files.

A VTL contains the following directories and files:

 
Table 40. VTL directories and files
Windows
Linux and UNIX
Description

...\<vt>

.../<vtl>

VTL root directory.

...\<vtl>\drives

.../<vtl>/drives

Directory under the VTL root directory where the virtual drives are stored. NetVault Backup creates a subdirectory for each virtual drive in this directory.

...\<vtl>\media

.../<vtl>/media

Directory under the VTL root directory where the virtual media items are stored.

...\<vtl>\slots

.../<vtl>/slots

Directory under the VTL root directory where the virtual slots are stored. NetVault Backup creates a subdirectory for each virtual slot in this directory.

...\<vtl>\.serial

.../<vtl>/.serial

 

 

File residing in the VTL root directory. It contains a list of media barcodes and drive numbers.

For example, “4O4HR-2”, where “4O4HR” is the barcode and “2” is virtual drive number; 404HR-2”, where “404HR” is the barcode and “2” is virtual drive 2.

...\<vtl>\drives\<x>\.serial

.../<vtl>/drives/<x>/.serial

File residing in each drive subdirectory. It contains the individual media barcode and drive number.

...\<vtl>\slots\<x>\.serial

.../<vtl>/slots/<x>/.serial

File residing in each slot subdirectory. It contains barcode for the individual media item.

For example, “..\..\4O4HR001”, where “404HR” is the barcode and “001” is the virtual media item.

...\<vtl>\media\<mediafile>

.../<vtl>/media/<mediafile>

Actual virtual media. For example, ...\vtl1\media\4O4HR001.

To add a media item, use the following steps:

1
Stop the NetVault Backup Service on the machine where the VTL is located.
2
In the slots directory, create a subdirectory which is one number larger than the existing largest numbered virtual slot directory.
3
Copy the “.media” file from one of the virtual slot directories to the virtual slot directory created in the previous step.
4
Modify the “.media” file in the newly created virtual slot directory from “1Y2NY00*” to “1Y2NY00X”, where X represents the new virtual media number.
5
Use the nvmakemedia command to create the media file.
6
Restart the NetVault Backup Service.
