Esxi 5.0 U2 - iScsi Hardware Initiator Multipath? (SOLVED)

Hi,

i have a Broadcom BCM5709 iScsi Card with TOE.

Is listed in "Storage Adapters", and i see 4 iSCSI Storage Adapters

I try to configure Multipath with a single Initiator, so i first created the 2 vswitch (on different subnets)

The i added the First Vswitch to vmhba32

But when i'll try to add the second Vswitch in order to obtain the Multipath

the second Vswitch is not listed and can't be added.

Why is that? How this can be solved?

Thanks
