I've been reading the Hitachi white paper on deploying ESX with GAD* and it mentions several failover scenarios that incur a "storage failover." However, the paper does not describe exactly what a storage failover is or what happens during a storage failover.
1. Can someone please define what happens during a storage failover?
2. I noticed that in the October 24, 2014 version of the paper, a quorum failure incurs a storage failover. However, in the similar June 18, 2015 document** a storage failover is no longer listed for a quorum failure. Has a later version removed that issue?
