definitions can be created. The critical volume could get 80 Mb of the bandwidth, and the lower priority
volume could get 20 Mb of the bandwidth.
15.6 Virtual machine recovery at a DR site
When recovering virtual machines at the disaster recovery site, the same general steps as outlined in the
section 14.2 should be followed.
Timesaver: If the environment has a significant number of volumes to recover, time can be saved during the
recovery process by using the replication recovery functionality within the DSM software. These features
allow an administrator to predefine the recovery settings with specifics such as the appropriate hosts,
mappings, LUN numbers, and host HBAs. After the recovery has been predefined, a recovery at the
secondary site is mostly automated.
Caution: It is important that the destination volume, denoted by Repl of, is never directly mapped to an ESXi
host while data is being replicated. Doing so will inevitably cause data integrity issues in the destination
volume, requiring the entire volume to be re-replicated from scratch. The safest recovery method is to always
restore the virtual machine from a local recovery or view volume as shown in previous sections.
