Fail back DR to HA Appliance

Use this procedure if you performed the failover steps outlined in Fail over HA Appliance to DR Appliance.

To fail back to local onQ Appliance:

1.	Determine how you’d like to synchronize the local onQ Appliance’s repository with the remote onQ Appliance’s repository, which has the most recent data.

If there is too much data consider an export/import instead of a WAN synchronization.

2.	Do one of the following based on the decision you made in Step 1.

•	If you want to synchronize the Repositories using WAN synchronization, ensure that the trust relationship is set up on the remote onQ Appliance.

•	If you want to synchronize the Repositories using export/import, remove the trust relationship on the remote onQ Appliance by setting an empty password.

3.	Schedule downtime based on the time needed to sync or export/import the repository data.

4.	During the scheduled downtime, log on to the remote onQ Appliance’s onQ Portal and do the following:

a.	Stop all the recovery nodes (which are acting as protected nodes).

b.	Stop protection.

5.	Power on the local onQ Appliance, if it isn’t already.

6.	Change the local onQ Appliance’s role to HA, if it isn’t already.

7.	Do one of the following:

•	If you chose WAN synchronization in Step 2, that process takes place as soon as the local onQ Appliance boots up. At this time, also ensure that the local onQ Appliance’s role is HA.

•	If you chose export/import in Step 2, ensure that the local onQ Appliance’s role is HA, then perform that export/import.

As the synchronization or export/import is in progress, proceed to Step 8.

8.	Log on to the local onQ Appliance’s onQ Portal, and do the following to address failures to the protected nodes, if applicable.

a.	Disable the protected nodes, so that the onQ Appliance does not perform backups during a restore.

b.	Start protection. A restore requires protection.

c.	Restore the protected nodes using one of the two methods:

•	bare metal restore (BMR)

•	file level restore (FLR)

•	Windows Share Restore (WSR)

9.	On the local onQ Appliance, bring up all the protected nodes. The boot order must take into account any interdependencies.

10.	Change the remote onQ Appliance’s role to DR.

11.	Restart protection.
