Unconfiguring NetBackup Snapshot Manager agents
To enable NetBackup Snapshot Manager to protect assets on a remote host, you first need to establish a connection between the NetBackup Snapshot Manager server and the remote host. Depending on how the connection is configured (either with agents or using the agentless feature), NetBackup Snapshot Manager uses agents that manage the plug-ins that are used to discover all the assets and perform the operations on the host.
Whenever you configure a remote host for protection, the agent registration and the plug-in configuration information is added to the NetBackup Snapshot Manager database on the NetBackup Snapshot Manager server. You can, if required, remove an agent entry from the NetBackup Snapshot Manager database by performing the disconnect operation from the NetBackup UI.
Before you unconfigure an agent, consider the following:
Once you unconfigure an agent, you cannot re-configure a NetBackup Snapshot Manager plug-in on the same host, if you had installed the NetBackup Snapshot Manager agent on that host. To be able to configure a plug-in on the host again, you must first uninstall the agent package from the host, connect the host and install and register the agent with the NetBackup Snapshot Manager server again.
You must first unconfigure the NetBackup Snapshot Manager plug-in from the host before you proceed with the disconnect operation. The disconnect option is not enabled if a NetBackup Snapshot Manager plug-in is configured on the host.
Unconfiguring an agent entry from the NetBackup Snapshot Manager server does not uninstall the agent package from the host. You have to manually remove the agent binaries from the host after completing the disconnect operation.
Once you unconfigure an agent, all the file system assets that belong to that host are removed from the NetBackup Snapshot Manager configuration.
To unconfigure the agent entry from the NetBackup Snapshot Manager server
- Sign in to the NetBackup UI.
- Remove NetBackup Snapshot Manager plug-in configuration from the host that you wish to disconnect.
- From the menu on the left, click Workloads > Cloud and then click the Virtual machines tab.
- On the Virtual machines tab, select the host where you want unconfigure the agent and then from the menu bar that appears at the top, click Disconnect.
NetBackup Snapshot Manager begins to unconfigure the agent. Observe that the Disconnect button now changes to Connect. This indicates that the disconnect operation is successful and the agent has been unconfigured successfully.
The agent registration and all the assets information about that host is completely removed from the database.
- The next step is to manually uninstall the agent from the host on which you performed the disconnect operation. This is required if you wish to protect this host and its assets using NetBackup Snapshot Manager at a later time.
