Full Description:
A redundant pair of SAN Volume Controller nodes (SVC nodes) provide "storage virtualization" capabilities to the Storage Farm service. These SVCs are in the data path between storage arrays and servers. The first SVC node was upgraded successfully. The upgrade for the second (of two) nodes did not complete normally, for unknown reasons. The storage service is still running, but without redundancy, until the second node can be upgraded. It is possible that some services may see a performance impact.
