Multiple Tape Library from different vendors can be configured.

Tape Overview

Manage the tape library directly with Nodeum.

Configuration of a Tape Library

To set up a tape library, follow these steps:

System -> Hardware -> Storage -> Tape Library

• Click on the Toggle Button "Discover tapes libraries information"

Tape Library Configuration - step1

• After click on the Toggle Button "Display non-configured libraries", Nodeum searches connections with tape Libraries

Tape Library Configuration - Step2

This action will automatically discover all connected tape libraries

Tape Library Configuration - Step3

• Select the Tape Library you need to configure and filled-in the following columns to complete the setup.

Mandatory Information	Description
Name	Complete a name
Emulation	Select the supported emulation for your Tape Library

• Once done, you can see that the selected Tape Library is now Configure and Ready.

Tape Library Configuration - Step4

Check the status of the Tape Library

Status	Description
Configured	Tape library is configured
Not Configured	Tape library is not configured
Ready	Tape library is connected and operational.
Not Ready	Tape library is either not connected or not operational.

Deactivate the automatic tape drive cleaning in the tape library. Only the manual mode is authorized by Nodeum.

Tape Drive Configuration

The next step is to configure the associated Tape Drive(s).

• click on the -> icon on the right of the Tape Library.

Tape drive Configuration - Step 1

• Click on the Toggle Button "Display non-configured drives".

Tape drive Configuration - Step 2

This action will automatically discover all connected tape drives and list all drives connected

Tape drive Configuration - Step 3

• Select the drives to link with the Tape Library and save the configuration

Tape drive Configuration - Step 3

Check the status of the Tape Drives

Status	Description
Configured	Tape drive is configured
Not configured	Tape drive is not configured
Online	Tape drive is connected and operational
Offline	Tape drive is connected but in maintenance mode

After completing this step, return to the Tape Library Configuration

Tape drive Cleaning

Before launching a tape drive cleaning, ensure that all tasks are stopped. During cleaning, the tape library will be offline, and no operations can run simultaneously.

Deactivate the automatic tape drive cleaning in the tape library. Only the manual mode is authorized by Nodeum.

Tape drive Replacement or other materials

In case of the tape library required to change a tape drive, replace the bridge or other materials, Nodeum need to resync with the new material information like the SCSI devices or other.

Sync the mapping of Tape Library and Tape Drive SCSI device(s)

When modifying the Tape Library and Tape Drives configuration, device assignments may change. Synchronizing the devices between both configurations is necessary in.

Tape Library sync

In the screenshot, the device in use is /dev/sg8. Clicking on Discover tapes libraries information initiates a scan

Tape Library Synchronisation - Step 1

This operation may take a few seconds or minutes, depending on the size of each tape library in terms of tape drives

Once the operation is finished, it will displayed the updated device, in this example /dev/sg4 and display the to highligh that there is an update.

Click on this icon to confirm the change(s).

Tape Library Synchronisation - Step 2

Tape Drives sync

The same operation can be performend into the Tape Drives configuration.

Tape Drive synchronisation - Step 1

In this example you can see in the red square the devices used by each Tape Drives:

Tape Drive synchronisation - Step 2

• Click the Display non-configured drives toggle to initiate a scan and automatically map new devices

Tape Drive synchronisation - Step 3

Tape Barcode Requirement

• Ensure the Tape Library is set up to display the full 8-character Tape Barcode, e.g., ABC123Lx, where 'x' represents the LTO version.

• Tape Barcode must be unique.

• if multiple Tape Libraries are configured, you are not allowed to use identical barcode in the different Tape Libraries !
