iSCSI LIFs will not migrate when SFO, so in the two different test scenario,(assume in 2node-cDOT8.3, every node has 2 iSCSI LIFs)
1) take down the optimized LIFs; -> client IO will interrupte for 15s;
2) take down the local node; -> client IO will interrupte for less than 1s;
both the two operations will cause the optimized LIFs become unavailable, client IO will try to switch to the patner path. Why are the behaviors different in the above two scenario.
