Can you please elaborate on this?
I think the correct setting depends on the configured
"host persona". Currently the expected value would be
"Generic / 1". The patch changes it to "Generic-ALUA / 2".
Does the above change still work if the "host persona" is
not modified and still set to "Generic / 1"?
