Planning for AFM DR

The following topics assist you in planning for AFM DR.

Requirements for UID/GID on primary and secondary clusters
User IDs and group IDs must be managed the same way across the primary and secondary clusters.
Recommended worker1Threads on primary cluster
IBM® recommends that you increase the worker1Threads to twice the number of AFM DR filesets that are using GPFS backend, which exist on all file systems in the cache cluster.
NFS setup on the secondary cluster
NFS setup on the secondary cluster follows the same rules as the NFS setup on the AFM home cluster.
General guidelines and recommendations for AFM-DR
AFM-DR is a disaster recovery solution, which is by nature a business-critical solution. Its success depends on administration discipline, including careful design, configuration, and testing. Considering this, IBM requires that the AFM Async DR (AFM-ADR) deployment must follow certain guidelines and recommendations for the deployment. The AFM-ADR feature is disabled by default and it can be enabled by following the recommendations and guidelines.
