Isilon zone alias and smart connect pool.

I have a 10 node xnode Isilon 7.2.x code. I have many zone aliases with 5 pools created. I need to isolate a zone alias(Testalias) to a specific pool. I need to make sure the zone alias accesses only one pool. Is this the command that I need to run for the alias to only connect to a specific pool? isi networks modify pool subnet0:Testpool --add-zone-aliases=Testalias.corp.ent.xxxx.org
