NetVault 13.0 - Administration Guide

Re-adding a previously created SVTL

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

To re-add a previously created SVTL:

Start the device configuration wizard.

On the Add Storage Devices page, select the Shared virtual tape library option and the Re-add previously generated virtual device check box.

In the list of NetVault machines, select the machine on which the device was created. Click Next to scan the selected client and list the discovered SVTLs.

In the Device list, select the device that you want to add, and click Next.

After the SVTL is added, and the tape drives are automatically discovered and assigned to the appropriate storage bays, a message is displayed.

You can use this default configuration if all drives are to be controlled by the client selected in Step 3. In this case, click Add Library. Information message appears. Close the message to exit the configuration wizard.

To assign the drives to different clients or to share the drive with multiple clients, click Add Drives Manually, and 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. Click Next to scan the selected client and list the attached devices.


	NOTE: To skip any bay and configure the next bay, click Leave bay empty.

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

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.

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

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