Start recovery nodes on DR Appliance or DR Mirror

In the event of a disaster, you might need to start all the recovery nodes on the DR Appliance.

It’s possible to allocate resources to recovery nodes beyond what is physically available on the onQ Appliance. If you don’t have enough memory to start all the recovery nodes, you have two choices:

•	You can change the memory allocation of PNs so that the total is less than the memory on the onQ Appliance.

•	You can start your recovery nodes individually. The boot order must take into account any interdependencies.

•	You may be prompted to install application-specific software licenses upon startup of recovery nodes.

To start an individual recovery node in production mode:

1.	(Optional) Consider suspending RN tests to “free up” resources.

2.	(Redhat 5.x RNs) Install kernel‑xen RPM package.

3.	From the DR Appliance, go to DASHBOARD tab > RECOVERY NODES page.

4.	Locate the Power State column.

When you click the button in the Power State column, a box appears that offers you a choice between the following two alternatives: Power On: Test Network or Power On: Production Network.

5.	Choose the Power On: Production Network power option.

To start all recovery nodes in production mode:

1.	(Optional) Consider suspending RN tests to “free up” resources.

2.	(Redhat 5.x RNs) Install kernel‑xen RPM package.

3.	From the DR Appliance, go to DASHBOARD tab > DR STATUS page.

4.	Unlock the page.

5.	Locate Link Status.

6.	Click on the Link Status light (and the light is green). You are asked if you wish to Power On the DR RNs.

7.	Click Apply to start all the DR recovery nodes.
