I don't believe that is possible on a live system.  I have upgraded using
the Solaris sas2flash utility on a system with the pool exported.   The
last step of the flash function is to reset the adapter which fails
requiring the system to be rebooted.

What I haven't tried is disconnecting the SAS cables then applying the
update.   I suspect this may work, but is only a useful method if you have
redundant SAS paths and can do one HBA at a time.

These issues are why I run HA systems and can migrate my pools from server
to server and perform maintenance at a leisurely pace and confirm
everything is the way I want it before putting the server back in service.
