(Workflow) Fail back an RN to a PN

This workflow assumes that your enrolled PN went down for some reason, and that you failed over the PN to an RN as outlined in (Workflow) Fail over a PN to an RN. Now that you’ve fixed your original PN, use the failback procedure that pertains to your PN’s enrollment method to restore the original PN:

To fail back an agent‑based RN to a PN on the HA Appliance:

1.	Log on to the onQ Appliance’s onQ Portal.

2.	Change the onQ Proxy address of the PN, if you specified an RN network configuration different than the original PN as part of multi‑network support.

3.	Schedule some downtime. Prevent any further changes to the RN.

4.	Perform a backup of the RN in production mode.

5.	Shut down the RN in production mode.

6.	Perform an incremental restore of the PN, choosing the latest snapshot that you initiated in Step 4.

onQ resumes backups of this agent‑based PN.

To fail back an agent‑less RN to a PN on the HA Appliance:

1.	Log on to the onQ Appliance’s onQ Portal.

2.	Manually install the node software package on the RN.

3.	Change the onQ Proxy address of the PN, if you specified an RN network configuration different than the original PN as part of multi‑network support.

4.	Schedule some downtime.

5.	Perform a backup of the RN in production mode.

6.	Shut down the RN in production mode.

The Backup Mode switches from Recovery Node to Agentless.

7.	Boot the original PN using QUARK.

8.	Perform an incremental restore, choosing the latest snapshot that you initiated in Step 5.

onQ resumes backups of this agent‑less PN.

To fail back an agent‑less RN to a PN on the DR Appliance:

1.	Launch the DR Appliance’s onQ Portal.

2.	Shut down the RN in production mode on the DR Appliance.

3.	Restart the original PN in production mode on the DR Appliance.

4.	Re-enable backups of the PN:

a.	Go to APPLIANCE CONFIG tab > Modify a Protected Node page.

b.	Select the PN, then MODIFY.

c.	Switch the PN’s Backup Mode from Recovery Node to Agentless, then SAVE the configuration.
