We're blocking at the switch on the SAN. We're using Emulex. No, it's much slower to detect failure on balanced. Minq is close to the same for time to detect failure. But we like the adaptive performance we get better.

How are you doing the blocking? What are the storage HBA/drivers in use on the host? When you use other I/O policies, do you get significantly faster detection of path failure?
