about this:

BTW, each CM does not have an IP address.  Only the active CM does.  On failover the new CM inherits the IP addresses.

I have on one array configuration like that:

Thats is ok ?? or I must delete IP on e.g eth0 because status is secondary ?

ActiveCM:
eth0:192.168.171.171
eth1:192.168.171.172

The Standby CM doesnt have an IP konfig.

In the dynamic. discovery you have to enter the WKA(Well known Address) of the (iscsi)Group and never the eht0/1 IPs.

Yes your IP config for that member looks ok.

Btw. each of your ESXi hosts needs at least 2 VMKs for ISCSI so you need 2 IPs for every Hosts. Otherwiese you doesnt have a redundancy. Using swISCSI with a Single iSCSI Target like EQL(and some others) is special because you have to bind your VMKs to the swISCSI first and each VMK only have to be one acitve NIC and no StandBy NICs.

About the CMs,

click in the status tab and on member status health select "Rear view". Use the mouse and mopve over the CMs and the ETHs without  a mouse click. Maybe it explains more than written words.

In EQL land there is only a single IP configuration which is use by the active CM (Controler Module)

In vmware i configured sw like that - without install  multipathing extension module - thats is ok ??

For Arrays like EQL VMware says you have to use a single vSwitch.

Don,

VMware say its a "must". For sure it also works on different vSwitches and it wasnt a "must" in the early days.
