Configuring Hitachi TrueCopy replication and global clustering
After you complete the service group configuration task in the DR wizard, you configure replication and global clustering.
The wizard helps you to configure the settings for the HTC resource in the application service group.
Ensure that you have one static address is available per site for configuring GCO.
The wizard configures the required agent settings. It uses defaults for optional settings.
To configure Hitachi TrueCopy replication and GCO
- Verify that you have brought the application server service group online at the primary site.
- If the wizard is still open after the service group cloning task, continue with the Replication Setup panel.
Otherwise, launch the wizard and proceed to the Replication Setup panel by following these steps sequentially:
-
Start the DR Configuration Wizard from the Solutions Configuration Center by clicking or, on Windows 2012 operating systems, from the menu.
Expand the Solutions for Solutions for Additional Applications tab.
Click .
- In the Welcome panel, click and continue through the wizard, providing the requested information.
- In the Replication Methods panel, click . Click and continue to the Replication Setup panel.
- In the Replication Setup panel, review the replication requirements. If you have met the requirements, click .
Warning: |
Although you can continue with the wizard even if replication requirements are not met, the wizard will warn you that the configuration is not valid. If the configuration is not valid, the HTC resource cannot come online in the service group. |
- In the HTC Resource Configuration panel, the wizard populates the required resource fields if the horcm file is configured properly. If not, you can configure the
horcm
file and click to populate the fields. Alternatively, enter the required resource settings manually:
- If you want to configure an additional HTC resource for the instance, click . Otherwise, click .
- In the Global Cluster Settings panel, specify the heartbeat information for the wide-area connector resource. You must specify this information for the primary and the secondary cluster. Any existing WAC resource information can be reused. If you are adding a DR site to an existing DR configuration, GCO is already configured at the primary site, so the primary site fields are dimmed.
- In the Settings Summary panel, review the displayed information.
If you want to change any of the parameters specified for the replication resource settings or the global cluster settings, click .
Otherwise, click .
- In the Implementation panel, wait until the wizard completes creating the replication configuration and the WAC resource required for global clustering. A check symbol indicates successful completion of a task. An () symbol indicates a task that could not be completed successfully. The Information column shows details about the reasons for task failure. Click .
- In the Finish panel, review the displayed information. If a task did not complete successfully, the panel displays an error message, which will provide some insight into the cause for failure. Click to exit the wizard.
- Proceed with configuring additional optional settings for the HTC resource if desired, and then verifying the disaster recovery configuration.
