AFM-based Disaster Recovery

The following use cases inform you how AFM-based Disaster Recovery is deployed effectively.

Creating new primary-secondary filesets, failover and failback to old primary
This use case describes creating new primary-secondary filesets, checking RPO snapshot creation after RPO timeout, failing over to secondary, and failing back to old primary.
Convert GPFS-independent filesets to AFM DR, failover to secondary and failback to a new primary by using the outband trucking method
This use case scenario describes conversion of GPFS-independent filesets to primary-secondary using inband option, failover and failback to a new primary by using the outband trucking option.
Changing target protocol for AFM filesets
This use case describes change of protocol used by an AFM or AFM DR fileset from CES NFS to GPFS, or from GPFS to CES NFS.
Failback of multiple filesets
To minimize application downtime, consider running all of the failback steps for one fileset at a time.
Examples of using IBM Spectrum Protect for Space Management on DR filesets
The following examples illustrate use of for Space Management on DR filesets
Changing target protocol of primary filesets
The following examples illustrate how to change the target protocol used by a primary fileset from NFS to GPFS or vice versa.
Role reversal
This use case describes AFM DR role reversal process where secondary site/cluster takes over the role of a new primary site after a failure is observed at the primary site. After the old primary site is back online, the old primary is promoted to secondary site and replication between new primary and secondary site resumes. Roles of both sides are swapped.
