In simple term, we may consider Failover refer to load balancing. A CLARiiON array is an Active/Passive device and uses a LUN ownership model. In other words, when a LUN is bound it has a default owner, either SP-A or SP-B. I/O requests traveling to a port SP-A can only reach LUNs owned by SP-A and I/O requests traveling to a port on SP-B can only reach LUNs owned SP-B.  It is necessary to have different failover methods because in certain situations a host will need to access a LUN on the non-owning SP. Hence, the concept of Failover Mode.  There are different different failover modes, which are explained in detail in Primus emc157830.
Hi all,  We know that different hosts might have different Failover Mode settings with the storage array. But do we have a a standard definition for Failover Mode to better understand how does it work?  thanks!
do we have a standard definition for Failover Mode ?
