Unmounting a library from a node

How to unmount a library on the IBM Storage Archive Enterprise Edition system.

Before you begin

You must have root user authority to complete this task.

The eeadm node down command is used to disable a node, which causes the library to be unmounted from that node.

Complete the following steps on each node:

Disable the node by using the eeadm node down command:
```
eeadm node down <node_name> [-l <library_name>]
```
Confirm that the node is disabled by using the eeadm node list command:
```
eeadm node list
```
