Setting Lock Type on Servers

When you initially apply a template to one or more NIOS-X servers, the idea is to have all applicable servers adopt the service configurations defined in the template. However, if you want to control whether you can add, modify, or delete services on certain servers, The Infoblox platform offers lock type options. These options allow you to define how servers adopt service configurations while being associated with a template.
For a server associated with a template, the Infoblox platform indicates whether the services on the server have changed in relation to the template; this change is called drift. The Infoblox platform also calculates the drift state of a server when service changes are allowed on the server. The drift state implies whether the server to which a specified template is applied adheres to the defined specifications or not. The drift state can be True or False, as follows:
True: The server has drifted from the template and is no longer adhering to the template specifications.
False: The server has not drifted from the template and is still adhering to the template specifications.
The following lists the lock types and drift states on a server:
Lock Type | Drift State | Description |
|---|---|---|
Locked | False | When a server is Locked, it is associated with the applied template. Therefore, no service addition, modification, or deletion is allowed on the server. The drift state is False when a server is in the Locked state since there is no drifting from the template. If you want certain servers to adhere to all the updates made to the applied template, you can lock them to the template. In other words, whenever changes are made to the template, the services on these locked servers will be immediately reconciled based on changes made to the template. When you modify the template, the modification will apply to locked servers automatically, without you having to approve it. However, the modification will not apply to servers whose Lock Type is Unlocked or Monitored. |
Unlocked | N/A | When a server is in the Unlocked state, it is not locked to the applied template. Therefore, service addition, modification, and deletion on the server are allowed. The drift state is not calculated or displayed for an unlocked server, meaning the Infoblox platform does not perform any checks on the drift state. You can assign this lock type to a server if you want to be able to modify its services but do not need to monitor its drift state in relation to the applied template. |
Monitored | true or false | When you first apply a template to a server, the lock type of the server is set to Monitored, and the drift state is set to False. In this state, you can add new services to the server. When you do that, the drift state will change to True, indicating that services on the server have drifted from the applied template. You can assign this lock type to a server and monitor its drift state in relation to the applied template for testing purposes. |
To set the lock type on a server, do the following:
Log in to the Infoblox Portal.
Click the Configure > Servers tab.
Select the server on which you want to set the lock type, and click Edit. Note that you must first apply a template to the server before setting the lock type.
In the General Info step of the Edit <Server> dialog, choose one of the following from the drop-down menu of the Template field:
Locked: When you choose Locked, the server is locked to the applied template. Therefore, no service addition, modification, or deletion is allowed on the server. The drift state is False when a server is in the Locked state since there is no drifting from the template.
Unlocked: When you choose Unlocked, the server is not locked to the applied template. Therefore, service addition, modification, and deletion on the server are allowed. The drift state is not calculated or displayed.
Monitored:Â When you choose Monitored, you can add new services to the server. When you do that, the drift state will change to True, indicating services on the server has drifted from the applied template.
