Figure 7 Testing failover
.
This process will create a snapshot of the last PiT for the replicated virtual disk and assign host
permissions for the recovery site ESX host. Once host permissions of the snapshots are assigned to
the ESX host(s), Site Recovery Manager will start each of the VMs that are contained on the replicated
datastores. Once all the VMs have been brought online, the recovery plan will pause to allow
verification of the VMs. During this process, the IP addresses have been removed, so you will not be
able to access the VMs remotely, but can launch the console window to verify the status of the VMs.
After verification, click the Continue link to remove the VMs and snapshots from the Recovery Site ESX
host.
Performing a disaster recovery
Declaring a disaster and running the appropriate recovery plans requires manual intervention. Site
Recovery Manager can be set up at one site to notify administrators when communication with the
other site is lost. Using these alerts and other alerts, the administrator must decide when a disaster
has occurred and whether to carry out a recovery plan. Running a recovery plan is also called a
failover.
Running the disaster recovery plan
In case of a failure of some servers at the primary site, and it is deemed necessary to fail over to the
recovery site, the process is similar to the test plan with key exceptions. Failing over to the recovery
site is a one-way process in that to failback, you will need to configure the recovery site (now acting
as the protected site) and the protected site (now acting as recovery site) relationships (create inventory
maps, protection groups, and recovery plans) before you will be able to failback from the recovery
site. You would then need to run the new recovery plan to failback to the original protected site. Also,
when running the recovery plan, Site Recovery Manager will attempt to shut down any protected VMs
