Dell NetWorker 19.9 Administration Guide

Unmounting volumes automatically (idle device timeout)

At times, a volume that is mounted in one device might be needed by another device in the same library. For example, data being recovered by one device could span more than one volume, and the required volume could be mounted on another device. To address this need, a value can be defined in the Idle Device Timeout attribute for that particular library.

1. In the server’s NetWorker Administration interface, click Devices.
2. Open the Libraries folder in the navigation tree.
3. Right-click the appropriate library in the detail table, and select Properties. The Properties window appears.
4. Select the Timers tab.
5. Specify a value in the Idle Device Timeout attribute.

You can also override the library’s Idle Device Timeout attribute for a specific device in the library.

To specify the Idle Device Timeout value for a specific device:

6. In the server’s Administration interface, click Devices.
7. Select View > Diagnostic Mode.
8. Select Devices in the navigation tree. The Devices detail table appears.
9. Right-click the device and select Properties.
10. Select the Advanced tab.
11. Specify a value in the Idle Device Timeout attribute.

    The default value is 0 (zero) minutes, which means that the device never times out and the tape must be ejected manually. However, when the value of this attribute is set to 0, the value specified in the device library’s Idle Device Timeout attribute will take precedence.
