Hello,    The server never "learns" all the physical port IP addresses.   Dell PS Series SAN uses two required features of  iSCSI.   One, is called "login_redirect" and the other "async logout".   If you were to trace the login process, when the server tries to log into the Discovery Address it will fail, with a specific error message, and a physical port IP address will be sent to the initiator.  It will then immediately log into that physical port IP address.   When it comes time to balance an iSCSI session to another port, the server will receive an "async logout" request from the array.   Forcing it to logout, and log back in.  Where the first process is repeated, and the login is done on a different physical port.   Does that answer your question?    Regards,  Don 
If I have 3 PS6210 arrays in a group connected to an esxi 6 cluster via iscsi, do the vmnics learn all EQ eth ports during the initial discovery? I know the group IP is used for initial discovery, so I'm looking for the relationship between the host and EQ nics after that. We're considering a live controlled failover from our 1g switches to 10g switches, but  we can't lag the 10g to the 1g. All network connections are redundant (teamed nics, etc). I can give more details about the plan, but it depends on the answer about the eth relationships. Thanks.
