Virtual Tape Library considerations

Before creating and adding a VTL, review the following information:

•
Before creating a VTL, NetVault Backup performs a disk space check to ensure that the target disk has sufficient space to accommodate the new VTL.
On normal file systems you can use the disk space check feature to avoid errors during VTL creation. When creating a VTL on a third-party deduplication appliance or compressed file system, you should disable this feature. For more information, see Configuring default settings for Disk Devices Plug‑in.
•
During disk space checks the free space required on the disk is calculated as follows:
Number of Slots * Media Capacity + <x>
Here <x> is the additional disk space considered for the following requirements:
•
Disk space required to create the directory structure for VTL. The requirement varies for different file systems.
•
Disk space required by other applications running on the system.
By default, the additional space requirement is set to 20MB. To change this setting, see Configuring default settings for Disk Devices Plug‑in.
•
If the target disk does not have sufficient space to accommodate the specified VTL, the device emulation process is terminated and a message is displayed.

Creating and adding a Virtual Tape Library

You can use the configuration wizard to create a virtual tape library on the NetVault Backup Server or a SmartClient. When creating a VTL, you can choose the number of virtual tape drives and slots, and specify the size of the virtual tapes. After the device is created, it is automatically added to the server.

To create and add a Virtual Tape Library:
1
In the Navigation pane, click Guided Configuration, and then on the NetVault Configuration Wizard page, click Add Storage Devices.
— or —
In the Navigation pane, click Manage Devices, and then click Add Device.
2
On the Add Storage Devices page, select the Virtual tape library/media changer option, and click Next.
3
In the list of NetVault Backup machines, select the machine on which you want to create the device, and click Next.
4
On the Add Virtual Tape Library page, provide the following details.

Option
Description

Choose the location on disk where you wish to create the new device

Specify the location where you want to create the VTL.

Make sure that the path is already created on the selected machine. NetVault Backup does not create any non-existing directories in the path.

Choose a name for the device

Specify a unique name for the device.

Device display name

Specify a display name for the device.

Choose a 5 character media barcode prefix

The NetVault Backup Server automatically generates a barcode prefix and assigns it to the VTL media. If you want to change it, type a unique code for the device.

Specify the media capacity

Type or select the size of the virtual tape. The media size is specified in GiB. Each slot contains a piece of media of the given size. The default value is 32GiB.

Choose number of drives

Type or select the number of drives for the VTL. You can create maximum of 100 drives. The default value is two drives.

Choose number of slots

Type or select the total number of slots that hold the media. You can specify a maximum of 999 slots. The default value is 16 slots.

5
Click Next to create and add the device.
 
* 
NOTE: The amount of time it takes to create a VTL depends on the media capacity and number of slots specified for the VTL. The time required is proportional to the VTL size.
6
After the device is successfully added and initialized, a message is displayed.

Re-adding a previously created VTL

You can use the configuration wizard to find previously created virtual tape libraries and add the devices to the server. You can use this method to add a device that was removed from the server.

To re-add a previously created VTL:
1
Start the device configuration wizard.
2
On the Add Storage Devices page, select the Virtual tape library/media changer option and the Re-add previously generated virtual device check box.
3
In the list of NetVault Backup machines, select the machine on which the device was created. Click Next to scan the selected client and display the discovered VTLs.
4
In the Device list, select the device that you want to add, and click Next.
After the device is successfully added and initialized, a message is displayed.
