DKR has the following prerequisites:
• The CKMC must be the same for the DKR feature to connect and transfer data. The same KMC should be used for source and destination disks that are managed for disk replication.
• Disk replication takes care of key replication only and not the data replication as it is done by the storage vendor. Proper steps should be followed while syncing the keys.
Caution Once a disk is added to an DKR relationship all SME operations on that disk must be done only through DCNM-SAN. SME Disk configuration must not be done through CLI for disks involved in DKR relationship. Using the CLI results in unpredictable results and can put data on the disk at risk.
