Discovering the Oracle Zero Data Loss Recovery Appliance

From the Enterprise Manager home page, select the Setup menu (upper right corner), Add Target, and then Add Targets Manually.
On the Add Targets Manually page, click Add Targets Using Guided Process.
From the Add Using Guided Process window, select Oracle Zero Data Loss Recovery Appliance from the list and click Add.
On the Oracle Zero Data Loss Recovery Appliance Discovery page, the following two options are presented. This document details the steps for discovering a new Exadata Database machine and components:
- Discover a new Recovery Appliance and its hardware components as targets. The table will update to show the target types and the credentials required for discovery.
- Discover newly added hardware components in an existing Recovery Appliance as targets. Select a Recovery Appliance from the drop-down menu. The table will update to show the target types and the credentials required for discovery. The subsequent dialogs in the discovery flow will be similar to those depicted in this section but will be restricted to only undiscovered components.
Select the task and click Discover Targets. The Exadata Discovery Wizard begins.
On the Discovery Inputs page, enter the following information:
- For the Discovery Agents section:
  - Agent URL: Select an agent deployed on a physical compute node or if virtual Exadata on a domU (virtual machine) compute node. Click the search icon to select from available agents.
- For the Schematic Files section:
  - Once you have specified the Agent URL, a new row (hostname and schematic file information) is automatically added. The default schematic file, databasemachine.xml, describes the hardware components of the Exadata Database Machine.
  - Click Set Credential to set the credentials for the host.
  - Check and modify if necessary the schematic file location.
  - Select the schematic file name from drop-down menu.
Click Next.
The InfiniBand Discovery page looks different depending on whether the Oracle Zero Data Loss Recovery Appliance has been identified as having an InfiniBand (IB) or RDMA over Converged Ethernet (RoCE) storage network. Screenshots and the details for each option are shown below.
If this is an IB Recovery Appliance, the following information is required,
- IB Switch Host Name: The host name for one of the IB switches for the Recovery Appliance. The IB Switch hostname is usually pre-populated.
- InfiniBand Switch ILOM host credential: The root or ilom-admin user name and password for the InfiniBand switch ILOM host.
  Click Next.
If this is Recovery Appliance X8M, no credentials are required at this point in the discovery flow. The InfiniBand Discovery page will display a message that the Recovery Appliance to be discovered contains RoCE switches and no additional inputs are needed.

Click Next.

Note:
If this is Recovery Appliance X8M and the form displayed requests InfiniBand information, then it likely means there was an issue accessing the databasemachine.xml file specified in the previous step. Navigate back and correct this issue. Ensure the proper location and credentials are specified for the databasemachine.xml file and that the file exists.
On the Prerequisite Check page, Enterprise Manager will try to discover hardware components dynamically based on your environment. If any critical issues are encountered, then you can click Back to resolve them. Enterprise Manager will show the problem and its severity (Info, Warning, or Critical).
Any warning issues or informational messages may also be displayed. These do not interfere with the discovery process.

Click Next.
On the Components page, the components below are pre-selected. You can deselect any unwanted component. Components include, but are not limited to, the following:
- Compute Node: Select the hosts that are compute nodes in the Oracle Zero Data Loss Recovery Appliance.
- Oracle Exadata Storage Server: Select the Recovery Appliance Storage Servers that are part of this Oracle Zero Data Loss Recovery Appliance target.
- InfiniBand Switch: Displayed if this is an IB Recovery Appliance. Select the InfiniBand Switches that are part of the Oracle Exadata Database Machine. These also will be added as managed targets.
- Ethernet Switch: Select the Ethernet switches that are part of the Oracle Zero Data Loss Recovery Appliance. If this is an IB Recovery Appliance, select the admin switch. If this is Recovery Appliance X8M, select the admin and RoCE switches. The Ethernet switches will be added as managed targets.
- Compute Node ILOM: Select the Integrated Lights Out Managers (ILOMs) of the compute nodes that are part of this Oracle Zero Data Loss Recovery Appliance. These ILOMs will be added as managed targets.
Note:
A partitioned rack can list other components that should be deselected manually (for example, compute nodes).

Click Next.
By default, the agents are automatically assigned to the targets. To add more monitoring agents:
In the Monitoring Agents page, click Select Agents > in the pop-up window, select the required agents for each target on the Exadata Database Machine. Use the Ctrl key to select multiple agents.

Note:
A Warning will be thrown if only one agent is used as monitoring and backup agents. Click Select Agents and add more agents, if available.

Click Next.
On the Credentials page, set the credentials for all components within the Oracle Zero Data Loss Recovery Appliance (for example, the Storage Server, PDU, InfiniBand Switch, and so forth). Click Set Credential to set the credential for the component. If the users and passwords are the same for all components of the type, choose Same for all and enter the user and password combination.
Click Next.
On the Review page, verify each section is correct. The following figure shows an example of an accurate review.
Click Submit.
After the Recovery Appliance components are discovered, a Target Creation Summary page displays to show all discovered targets and components. If there are any errors, the Status column will display a red flag. Place your cursor over the flag for a pop-up window for additional information about the error.
Perform post-discovery verification before you begin using Enterprise Manager.
