Question 15

DRAG DROP
A non-production environment has been created with a VMFS Datastore named TestDS and a virtual
machine named TestVM. SRDF/S has been configured between two PowerMax arrays One ESXi
server is connected to the R1 device and another is connected to the R2 device. The VMFS Datastore

recovery readiness To simulate a disaster on the R1 side a graceful failover will be done. What is the
correct sequence of steps on the R1 side of the test environment to perform a graceful failover?
