This article contains the instructions on installing and configuring Druva Phoenix on a SQL failover cluster environment that has multiple nodes.
Shared storage that is configured and accessible to the cluster and all nodes.
On a high level, there are five steps to configure Druva Phoenix for the backup of a SQL failover cluster. As an example for this article, there are three nodes in the cluster, NODE01, NODE02, and NODE03.
- Step 1: Add the shared disk to all the cluster nodes
- Step 2: Configure clustered shared volume to install Druva Phoenix
- Step 3: Install Phoenix agent on the shared drive
- Step 4: Add Phoenix agent service as SQL Failover Cluster Instance Resource
- Step 5: Ensure that Druva Phoenix service is active only on the node where FCI is running
The following flow diagram summarizes the procedure for configuring Druva Phoenix for the backup of a node-based SQL failover cluster:
Step 1: Add the shared disk to all the cluster nodes
- Log on to the NODE01 machine.
- Launch the Disk Management console.
- Right-click on the shared disk and select Online to bring it online.
- Right-click again on the disk and start the New Simple Volume Wizard.
- On the first dialog, click Next.
- Specify the Simple Volume Size in MB. Click Next.
- For easier access, assign a drive letter to the disk; for example, P and click Next.
- Enter a volume label in the Volume Label text box; for example, Druva Phoenix and click Next.
- Click Finish and wait for a few seconds for the format operation to complete. Your disk is formatted with the NTFS file system.
Step 2: Configure clustered shared volume to install Druva Phoenix
- Launch the Failover Cluster Manager console.
- On the left pane, expand Storage and select Disks.
- Click Add Disk in the Actions pane on the right-hand side. You can see your newly added shared disk in the pop-up window. Select the disk and click OK.
- In the Disks section, right-click on the disk and select Properties. Rename the disk as PhoenixDisk (or any name that you may prefer). Click Apply and OK.
- Right-click on the disk and select Add to Cluster Shared Volumes. The drive is added to your node. Now, the drive is added as a CSVFS disk. Assign a letter to this disk.
- Before you can assign a letter to the disk, the Owner Node of the disk must be the same as the node you have logged on to (in this case NODE01). To ensure that NODE01 is the Owner Node:
- Select the CSVFS disk (in this example, the disk with PhoenixDisk as its name).
- After you select the disk, click Move Available Storage > Select Node.
- On the Move Cluster Shared Volume dialog box that appears, select the node you are logged on to (NODE01 in this example).
- To assign a letter to this disk, launch the Disk Management console.
- On the Disk Management console, right-click on the shared disk and launch the New Simple Volume Wizard. Follow the steps in the wizard and assign a letter to the disk (for example, P).
Step 3: Install Phoenix agent on the shared drive
- Download the MS-SQL agent for Druva Cloud on all nodes in the cluster.
- Log on to NODE01. For the sake of simplicity, assume that drive P: is the shared drive that you have created as clustered shared volume across all nodes on which you want to install Druva Phoenix.
- Start the installation for Druva Phoenix using the downloaded Installer.
- Accept the license and click Next.
- If you want to use a domain account, disable the Use Local System Account option and provide the domain account credentials. Provide the domain account username in the format: domain\username.
- In the Install Location box, enter the directory of the shared storage; for example, if P: drive is your shared directory, replace C with P and click Install. The installer copies all the necessary files on the given shared directory P:.
- After the installation completes, click Finish. The Phoenix agent is now installed on the P: drive.
If you use a domain account while installing the Phoenix agent, ensure that you add the same account in the Credential store to ensure that the credentials are preserved post an agent upgrade. For more information see Manage credentials for MS-SQL servers.
- Stop the Druva Phoenix service.
- Go to the C:\ProgramData directory. Move the Phoenix folder to the shared directory P:; for example, move it to P:\SharedProgramData\.
Note: This step of moving the Druva Phoenix folder is required only at the first login on the first node. For the other nodes, you can delete the Druva Phoenix folder from C:\ProgramData directory after stopping the Druva Phoenix service as you have moved the Druva Phoenix folder to the shared location P:\SharedProgramData. This location is accessible to all nodes.
To make Druva Phoenix access its local data and configuration files, create a junction point that points to the newly created Druva Phoenix folder location on the shared drive P\SharedProgramData\Phoenix. This step must be performed on all nodes. Launch the Command Prompt and create a junction point using the following command:
Mklink /j C:\ProgramData\Phoenix P:\SharedProgramData\Phoenix
Log onto the next node, NODE02, and follow the steps from 2 through 9 to install Druva Phoenix.
- If you have a configuration with more than two nodes, you must install Druva Phoenix on all the nodes by following the steps through 2 to 9. You must maintain the same folder structure on all nodes for installing Druva Phoenix.
- After the installation is complete, stop the Druva Phoenix service on all the nodes except the active node that you are going to register and configure with Druva Phoenix. For example, if you are planning to register your SQL failover cluster client using NODE01, which is the active node, Druva Phoenix Service must be stopped on all the other passive nodes. Druva Phoenix service should be started on active node NODE01.
- Register NODE01 and configure it for backup. To know the procedure for registering a server, refer to Register a Server.
Step 4: Add Phoenix agent service as a SQL Failover Cluster Instance Resource
- Open Failover Cluster Manager and select Roles in the left pane.
- Right-click on the SQL Server role and click Add Resource > Generic Service. The New Resource Wizard pop-up window appears.
- Select Druva Phoenix agent Client Service from the list of services displayed and click Next.
- The Confirmation section on the pop-up window appears. Verify the details and click Next to continue.
- The Configure Generic Service section on the pop-up window appears. Verify the details and click Next to continue.
- In the Summary section, to view the report created by the wizard, click View Report. Click Finish.
Step 5: Ensure that Druva Phoenix service is active only on the node where the FCI cluster is running
Ensure that the Druva Phoenix service is active only on the node where the FCI cluster is running. Stop the Druva Phoenix service on the rest of the nodes in the cluster. This is required for Druva Phoenix service failover.
To configure the Phoenix agent to use the Microsoft CSV Shadow Copy Provider, see How do I make the Phoenix agent use the Microsoft CSV Shadow Copy Provider?
You are now ready to back up your SQL failover cluster. Follow the steps described in Configure registered servers for backup for creating a SQL backup set.
