The Subpaths Failover Groups (SFG) feature can be turned on or off using the tunable dmp_sfg_threshold.

To turn off the feature, set the tunable dmp_sfg_threshold value to 0:

# vxdmpadm settune dmp_sfg_threshold=0

To turn on the feature, set the dmp_sfg_threshold value to the required number of path failures which triggers SFG. The default is 1.

# vxdmpadm settune dmp_sfg_threshold=N

The default value of the tunable is "1" which represents that the feature is on.

To see the Subpaths Failover Groups ID, use the following command:

# vxdmpadm getportids {ctlr=ctlr_name | dmpnodename=dmp_device_name \
    | enclosure=enclr_name | path=path_name}
