someone made probably misconfiguration when connecting Vcenter with NAS using iSCSI. There are to NICs set from ESXi side for iSCSI traffic but only one is used. It was configured to use same NIC for two iSCSI portgroups. Both iSCSI portgroups have same dvUplink1 active – second DVportgroup should have DvUplink2 active (with second NIC).
Is it possible to change right now Teaming and failover order to use dVUplink2 not dvUplink1 in a portGroup when there are some prod VMs running there right now ?
Paths from one dvPortgroup should stay active during change probably, right ?
