Site Recovery Manager and Virtual Machines Attached to RDM Disk
Devices
Protection and recovery of virtual machines that are attached to a raw disk mapping (RDM) disk device is
subject to different support depending on whether you use array-based replication or vSphere Replication.
NOTE Site Recovery Manager does not support the protection of virtual machines attached to RDM devices
in storage policy protection groups.
n
Array-based replication supports RDM devices in physical compatibility mode and in virtual
compatibility mode. If you use Site Recovery Manager with array-based repliction, you can protect and
recover virtual machines that use RDM in either physical compatibility mode or virtual compatibility
mode.
n
vSphere Replication supports RDM devices in virtual mode only, for both the source and target device.
If you use vSphere Replication, you cannot protect and recover virtual machines that use RDM in
physical compatibility mode.
n
If you use both array-based replication and vSphere Replication, you can only protect and recover
virtual machines that use RDM in physical compatibility mode by using array-based replication. You
can protect and recover virtual machines that use RDM in virtual compatibility mode by using either
array-based replication or vSphere Replication.
Site Recovery Manager and Active Directory Domain Controllers
Active Directory provides its own replication technology and restore mode.
Do not use Site Recovery Manager to protect Active Directory domain controllers. Use the Active Directory
replication technology and restore mode technologies to handle disaster recovery situations.
