There are various operations that can be performed on MRA Associations.
These operations include:
- Manual Sync
Manually starts a sync task on all MRA servers in the association.
- Cancel Sync
Cancels a sync which is currently in progress.
- Manual Migration
Manually starts a migration task on all MRA servers in the association.
- Cancel Migration
Cancels a migration which is currently in progress.
- Accept Migration
Accepts the migration (after all MRA servers have finished running the migration task).
Note: This operation will disable the migration mode on the MRA servers so that they will fully transition into using the N-site feature. All MRA servers in the association must either be in Migrated or Failed Migration status.
- Reset Counters
Resets all counters on all MRA servers in the association.
- Reapply Configuration
Reapplies the configuration to all MRA servers in the association.
Note: If at least one MRA server in the Association has a software version less than the version where this feature is introduced, the CMP displays a warning that clusters are in a mixed version, and the Operations drop down will be disabled. This is to prevent running operations on servers which do not have the required software to support those operations.
