The Joint T10/T11 Activity Working Group Minutes from the meeting
last week indicates there was discussion of the FC Control mode
page RHA (alias DSA) bit. The minutes indicate the discussion
included disallowing the RHA bit for fabric attachment.

The requirement for a hard address is still valid for fabric
environments. Switches are increasingly being incorporated into
storage systems. Those private loop JBOD products are migrating to
public behavior. The association of an address to a physical
location is still a desired feature.

Fabrics already have to handle address changes due to
configuration changes and power cycling. A change of address due
to a hard address change should be an infrequent event due to a
configuration error.

Am I missing a problem with RHA support in public configurations?
