14.7 Enterprise Remote Copy Management Facility (eRCMF)
eRCMF is a
When a site failure occurs or may be occurring, eRCMF splits the two sites in a manner that allows the backup site to be used to restart the applications. This needs to be fast enough that when the split occurs, operations on the production site are not impacted.
It manages the states of the Metro Mirror and FlashCopy relationships, so that the customer knows when the data is consistent and can control on which site the applications run.
It offers easy commands to place the data in the state it needs to be in. For example, if the data is out of sync, the command resync will cause eRCMF to scan the specified volumes and issue commands to bring the volumes back into sync.
It offers a tool to execute eRCMF configuration checks. This check is intended to verify that the eRCMF configuration matches the physical DS6000 setup in the customer environment. This is required to discover configuration changes that affect the eRCMF configuration as well. Regular checks support customers in keeping the eRCMF configuration
eRCMF is a IBM Global Services offering. More information about eRCMF can be found at:
