Where were Jay-Z, Nate Dogg, and Warren G, and Snoop Dogg in the East Coast West Coast Rivalry Feud?

Where were they at the time? Meaning what were they doing? Were they also taking part in this whole thing? Like was Warren G and Snoop Dogg siding with Tupac and the Westcoast and also dissing the East coast rappers? And were the East Coast rappers like Jay-Z, were they dissin the west coast rappers right back?
