DR group concepts DR group pairs (source and destination) DR groups operate in a paired relationship, with one DR group being a source and the other a destination. The terms source and destination are sometimes referred to as a DR mode or DR role. The terms source and destination are also applied to virtual disks, with a destination virtual disk also being known as a remote copy. Various actions, such as a planned or unplanned failover, allow you to reverse the relationship so that the source DR group becomes the destination and destination becomes the source. See DR groups failover. IMPORTANT: The role of a DR group in remote replication is of critical importance and can be reversed at any time. For example, a DR group can be a source at 8:00 and then, after a user-initiated failover, be a destination at 8:05. When reviewing a DR group's role, ensure that you are looking at current properties. In a typical environment, hosts perform I/O with the virtual disks in the source DR group at one site and the data is remotely replicated to the destination DR group at another site. The virtual disks in a source DR group remotely replicate to the same destination, fail over together, share a DR group log, and preserve write-order within the group.
