add irules in vs

Unlike many properties where you can use 'add/remove/replace-all-with', this syntax is not available in tmsh for editing the list of irules attached to a virtual server.

You will need to set the entire list every time

So if your current server has

rules {
    rule1
    rule2
}

and you want to add rule3, you'll need to set all three rules in one command:

tmsh modify ltm virtual server vs1 rules { rule1 rule2 rule3 }
