max-write-alloc-blocks option in 7.3.7p1

Couldn't find where to set max_write_alloc_blocks option value.

Want to play with this option on FAS2020 with 7.3.7p1.

Found only that on pre 7.3.2 versions it was done with setflag command.

Then in 8+ versions it was on aggr and vol options.

in 7.3.7p1 can't find this option anywhere.

Does anyone know where to set it?

In 7.3.2 that is when Flexvols were introduced which would make sense for a change then. I'm not seeing it discussed many places, I see it reference here: http://www.netapp.com/us/media/tr-4384.pdf. So in your 7.3.7 installation are you not seeing it as an aggregate option? Is there something in particular you are trying to achieve with this?
