SAN Volume Controller Cluster Limitation
when working with PPRC/Remote Copy Services

Debi Riedel

Condition:
The SAN Volume Controller cluster has a known limitation when working with PPRC/Remote Copy services. If the primary and auxiliary node become disconnected during operation, the information about the PPRC relationships can become unavailable on the primary cluster. The information is still available on the auxiliary cluster.

 
Workaround:
The relationships information will become available and fully functional if the clusters are reconnected. The ability to delete the relationship is still available at all times via the GUI or CLI interface. There are no adverse affects to this limitation other than the availability of information.
