Configuration of a Tape Library

To configure a tape library, follow these steps:

1. Navigate to: System -> Hardware -> Storage -> Tape Library

2. Click the toggle button labeled "Discover tapes libraries information"

Tape Library Configuration - step1

• After clicking the "Display non-configured libraries" toggle button, Nodeum searches for connections with tape libraries.

Tape Library Configuration - Step2

This feature will automatically detect all connected tape libraries.

Tape Library Configuration - Step3

• Choose the Tape Library you wish to configure. Complete the setup by filling in the required columns.

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

• The selected Tape Library is now configured and ready.

Tape Library Configuration - Step4

Check the Tape Library status

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.

To disable the automatic tape drive cleaning feature in the tape library, switch to manual mode as authorized by Nodeum.

Tape Drive Configuration

To configure the Tape Drive(s), click the -> icon next to the Tape Library.

Tape drive Configuration - Step 1

• Click the "Display non-configured drives" toggle button.

Tape drive Configuration - Step 2

Automatically detect and list all connected tape drives.

Tape drive Configuration - Step 3

• Choose the drives to connect with the Tape Library and then save the configuration.

Tape drive Configuration - Step 3

Verify 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

Once this step is finished, go back to the Tape Library Configuration.

Tape drive Cleaning

Before initiating a tape drive cleaning, ensure all tasks are paused. The tape library will be offline during this process, and no operations can occur concurrently.

To deactivate the automatic tape drive cleaning in the tape library, enable only manual mode as authorized by Nodeum.

Tape drive Replacement or other materials

To update the tape library when changing a tape drive, replacing a bridge, or other components, Nodeum must resynchronize to recognize new material information, such as SCSI devices.

Synchronizing Tape Library and Tape Drive Devices

When updating the configuration of Tape Libraries and Tape Drives, it's essential to ensure device assignments remain accurate as they may change. Here's how to sync them effectively:

1. Identify Current Device in Use The device currently in use appears as /dev/sg8.

2. Scan for Tape Libraries Click on Discover tapes libraries information to initiate a scan and update the device mappings.

Tape Library Synchronisation - Step 1

This process might take a few seconds to several minutes, based on the number of tape drives in the library.

Notice the update by clicking the icon to confirm the changes.

Tape Library Synchronisation - Step 2

Tape Drives sync

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

Tape Drive synchronisation - Step 1

The red square highlights the devices used by each tape drive:

Tape Drive synchronisation - Step 2

• Toggle Display non-configured drives to scan and map new devices automatically.

Tape Drive synchronisation - Step 3

Tape Barcode Requirement

• Configure the Tape Library to display the entire 8-character Tape Barcode, such as ABC123Lx, where 'x' indicates the LTO version.

• Ensure each Tape Barcode is unique.

• If multiple Tape Libraries are set up, do not use identical barcodes across different Tape Libraries.
