3. If you have not already, install SRM and HP EVA Virtualization Adapter on the updated hardware at the protected site (Site A). 4. Using the VI Client at the recovery site (Site B), establish the protected site (Site A) as the remote site for the recovery site (Site B). 5. Configure array replication from the recovery site (Site B) to the protected site (Site A) for datastores containing recovered virtual machines. For more information, see the HP StorageWorks Continuous Access EVA administrator guide. 6. Create any protection group(s) (P2) at the recovery site (Site B) to protect the recovered virtual machines at the protected site (Site A). 7. On the protected machine (Site A) create a recovery plan (R2) for the protection group(s) (P2) 8. After the virtual machines have been fully replicated to the protected site (Site A), execute recovery plan R2 at the protected site (Site A) in test mode. 9. If the test is successful, execute the recovery plan (R2) in recovery mode. If desired, you can now protect the recovered virtual machines on the protected site (Site A) back to the recovery site (Site B). To do this, perform the following steps: 1. Delete the recovery plan R2 from the protected site (Site A). 2. Delete the protection group(s) P2 at the recovery site (Site B). 3. Configure array replication from the recovery site (Site B) to the protected site (Site A) for datastores containing recovered virtual machines. For more information, see the HP StorageWorks Continuous Access EVA administrator guide. 4. Create protection group(s) P3 at the protected site (Site A) to protect recovered virtual machines from the protected site (Site A) to the recovery site (Site B). 5. Create a recovery plan R3 at the recovery site (Site B) for the protection group(s). Snapconfig utility The Snapconfig utility file is an xml file that is installed with HP EVA Virtualization Adapter, and is used during failover test operations.
