Installing a cluster-aware plug-in

In a cluster setup, the plug-in is installed by creating a virtual client on the NetVault Backup Server. All nodes in a cluster are grouped to form a virtual client. During the process, the plug-in is installed on the specified cluster nodes.

To install a cluster-aware plug-in:
1
In the Navigation pane, click Manage Clients.
2
On the Manage Clients page, and click Add Virtual Client.
3
On the Virtual Client page, provide the following information:
•
In Virtual Client Name, type a name for the virtual client. The name must be unique. Spaces are not recognized in a virtual client name and are replaced with an underscore (“_”) character. The virtual client name cannot be changed once it is configured.
•
In Virtual Client Address, type the IP address of the cluster application.
•
In the Package list, select the installation file for the plug-in. This list includes all cluster-aware “.npk” files copied to the packages directory and its subdirectories The following table provides the filenames for the installation files. Here x-x- x-x represents the version, build, and platform numbers.

•
To add a cluster node to the virtual client, select the client node in the Available Clients table, and click the Add button to the left of the item. The selected client is moved to the Chosen Clients table.
•
To remove a cluster node from the virtual client, select the client node in the Chosen Clients table, and click the Remove button to the left of the item. The selected client is moved to the Available Clients table.
4
Click Create Virtual Client.
The NetVault Backup Server starts installing the plug-in on the selected cluster nodes. This process overwrites the standard version of the same plug-in installed on the cluster nodes. However, you can use the cluster-aware version to perform backups of the local non-shared data. When the installation completes, the virtual client is added to the NetVault Backup Clients table on the Manage Clients page.

Upgrading a cluster-aware plug-in

To upgrade a cluster-aware plug-in, the existing virtual client is removed and a new virtual client is created using the latest version of the plug-in.

To upgrade a cluster-aware plug-in:
1
Remove the virtual client that was created with the previous version of the plug-in. For more information about removing a virtual client, see Removing a virtual client.
2
Create a new virtual client using the upgraded version of the cluster-aware plug-in. For more information about installing the plug-in, see Installing and upgrading cluster-aware plug‑ins.
You must assign the old virtual client’s name to the new virtual client. If you change the name for the new virtual client, you cannot run the jobs that were defined for the old virtual client.

Configuring a cluster-aware plug-in

The configuration procedure for a cluster-aware plug-in includes the steps outlined in the following sections:

•
Configuring preferred network address for cluster nodes
•
Configuring default settings for a cluster-aware plug-in

Configuring preferred network address for cluster nodes

A cluster node has at least two network addresses:

•
Public IP Address: The address that is used by machines outside the cluster to communicate with cluster nodes.
•
Private IP Address: The address that is used by a cluster node to communicate with other machines within the cluster.

For each cluster node, you must configure the machine’s public IP address as the “Preferred Network Address” for the node.

To configure preferred address for cluster nodes:
1
Obtain the IP address for the cluster node.
You can use the ifconfig utility on Linux and UNIX and the ipconfig utility on Windows to complete this step.
2
In the Navigation pane, click Change Settings.
3
On the Configuration page, click Client Settings. In the NetVault Backup Clients table, select the target client, and click Next.
4
On the Client Settings page, under Services, click Network Manager.
5
In the Network Manager dialog box, specify the preferred network address for the cluster node in the corresponding box.
6
Click Apply to apply the new settings and close the dialog box.
7
Repeat Step 1 through Step 6 for each cluster node.
