NetVault 13.2 - Administration Guide

In NetVault, the Drive Transfer Buffer Size option is set to 8 MiB by default.To ensure that this configuration is supported on your system. If this value is too high, change it to 257 KiB in the template file by , completing the following steps.

To change the default setting for the Drive Transfer Buffer Size option:

Open the file “drives.tpl” in a text editor.

You can find this file in <NetVault home>\devices\drives on Windows and <NetVault home>/devices/drives on Linux and UNIX.

In the [Device:Total Buffer Size] section, set Value to 257.

For example:

Value = 257

Save the changes and close the file.


	NOTE: If Drive Transfer Buffer Size is set too high and NetVault fails to allocate the transfer buffers, the backup jobs using tape devices show reduced performance.

Adding a standalone tape drive

You can use the configuration wizard to add and configure a standalone tape drive. The wizard lets you configure the device for shared access if it is connected to multiple hosts.


	NOTE: On Windows-based machines, you must disable the Removable Storage Service before adding a device to the NetVault Server. For more information about disabling this service, see the Quest NetVault Installation Guide.

To add a standalone tape drive to the NetVault Server:

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.

On the Add Storage Devices page, select the Single physical tape device option, and click Next.

In the list of NetVault Clients, select the client that is physically connected to the target device. If the device is connected to multiple clients, select any one client.

Click Next to scan the selected client and list the attached devices.

In the Choose drive table, select the device that you want to add.

In the Device display name box, provide a display name for the tape library.

Click Next.

If the device is connected to multiple clients (for example, in a SAN setup), all host clients are listed in the Choose Machines table. To share the drive with multiple clients, select the clients in the Choose Machines table, and click Next.

This page is not displayed if the drive is connected to a single client.

After the device is successfully added and initialized, a message is displayed on the page.

Adding a tape library

You can use the configuration wizard to add and configure a physical tape library. The wizard lets you configure the device for shared access if it is connected to multiple hosts.


	NOTE: On Windows-based machines, you must disable the Removable Storage Service before adding a device to the NetVault Server. For more information about disabling this service, see the Quest NetVault Installation Guide.

To add a tape library to the NetVault Server:

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.

On the Add Storage Devices page, select the Tape library/media changer option, and click Next.

In the list of NetVault Clients, select the client that is physically connected to the target device. If the device is connected to multiple clients, select the client that you want to designate as the library controller.

Click Next to scan the selected client and list the attached devices.


	NOTE: In NetVault, a library changer is always controlled by a single machine. The drives can be shared among multiple clients.

In the Choose library table, select the device that you want to add.

In the Tape Library Display Name box, specify a display name for the tape library.

Click Next.

After the tape drives are discovered and assigned to the appropriate storage bay, a message is displayed.

To use this default configuration, no further action is required. You can exit the configuration wizard.

If the library is not configured automatically, click Add drives manually. You can also use this method to assign the drives to different clients or to share the drive with multiple clients.

To manually select the controlling client and drive for each drive bay in the library, complete the following steps:

In the Choose Machine table, select the client to which the drive is attached. If the device is connected to multiple clients, select any one client.

Select the applicable option:

•

Scan for devices: To scan the client again for attached devices, select this option.

•

Do not scan for devices: To use the previous scan results, select this option.

•

Scan only filer: To scan for devices attached to a particular filer, select this option, and then select the applicable filer.

This option is only displayed if you have installed the Plug-in for NDMP on the server and added a filer to the plug-in.

Click Next.


	NOTE: To skip any bay and configure the next bay, click Leave bay empty. To leave the remaining bays empty and complete the library addition with the required drives, click Leave remaining bays empty.

In the Choose drive for bay table, select the device that you want to add, and click Next.

If a drive is available as both a SAN- and an NDMP-attached device, adding the drive as one type removes the other type from the list of available drives.

This page is not displayed if the drive is connected to a single client.

After the drive is successfully assigned to the selected clients, a message is displayed.

To assign additional drives for the library, click Add more devices, and repeat Step a through Step c until all required drives are configured.

If you do not want to add any other drives, exit the configuration wizard.


	NOTE: Inventory scanning during library initialization is faster for tapes with barcodes than tapes without barcodes. Therefore, using barcodes is recommended for all types of data and cleaning tapes.
