Protocols cluster disaster recovery
Protocols cluster disaster recovery (DR) uses the capabilities of Active File Management (AFM) based Async Disaster Recovery (AFM DR) features to provide a solution that allows an IBM Storage Scale cluster to fail over to another cluster and fail back, and backup and restore the protocol configuration information in cases where a secondary cluster is not available.
Important: This feature is being deprecated.
For
more information on AFM-based Async DR, see AFM-based asynchronous disaster recovery (AFM DR).Important: Our initial feedback from the field suggests that success of a disaster
recovery solution depends on administration discipline, including careful design, configuration and
testing. Considering this, IBM® has decided to disable the
Active File Management-based Asynchronous Disaster Recovery feature (AFM DR) by default and require
that customers deploying the AFM DR feature first review their deployments with IBM
Storage Scale development. You should contact IBM
Storage Scale Support at scale@us.ibm.com to have your use
case reviewed. IBM will help optimize your tuning parameters
and enable the feature. Please include this message while contacting IBM Support.
These limitations do not apply to base AFM support. These apply only to Async DR available with the IBM Storage Scale Advanced Edition 4.2 and 4.1.1.
