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 Spectrum 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.
For more information on AFM-based Async DR, see AFM-based Asynchronous Disaster Recovery (AFM DR).
These limitations do not apply to base AFM support. These apply only to Async DR available with the IBM Spectrum Scale Advanced Edition V4.2 and V4.1.1.
For more information, see Flash (Alert): IBM Spectrum Scale (GPFS) V4.2 and V4.1.1 AFM Async DR requirement for planning.
Although an overview of the steps that need to be done is provided if performing these operations manually, it is recommended to use the mmcesdr command because it automates DR setup, failover, failback, backup, and restore actions. For more information, see mmcesdr command.
