Creating a replica
Once you have paired two appliances, you can create replicas of your primary server application instances on either appliance.
Note:
The appliance where you create the replica must have enough available storage to accommodate the size of the instance. Both appliances also require up to an extra 20% of the size of the instance to be reserved for replication logging.
Use the following procedure to create a replica.
To create a replica
- Sign in to the Flex Appliance Console on the appliance that you want to create the replica on.
- Click the Remote replication icon in the left-side navigation bar, then click Create replica.
Alternatively, you can navigate to the Application instances section of the System topology page and click Create > Create replica.
- Locate the instance that you want to create a replica of.
If any prerequisites are not met for that instance, it is greyed out, and the Status column shows Missing prerequisites. Click Missing prerequisites to see the list of issues. You must resolve them before you can continue.
- Select the instance and click Next.
- Follow the prompts to create the replica. When you are done, the replica appears on the Remote replication page with a status of Configuring. You can view the progress in the Activity Monitor.
Once the replica has been created, the Remote replication page on the remote appliance updates as well. The instance that you created the replica of displays on this page as an active instance.
Note:
The instance widgets on the Remote replication page have different available actions, depending on whether they are for the active or the replica instance.
