Subpaths Failover Group (SFG)
A subpaths failover group (SFG) represents a group of paths which could fail and restore together. When an I/O error is encountered on a path in an SFG, DMP does proactive path probing on the other paths of that SFG as well. This behavior adds greatly to the performance of path failover thus improving I/O performance. Currently the criteria followed by DMP to form the subpaths failover groups is to bundle the paths with the same endpoints from the host to the array into one logical storage failover group.
