    Network Connectivity Lost - iSCSI Ports

    Marc P Enthusiast

      Hi

       

      I have an ESX host which is connected to 2 x 10GB switch (Dell N4032) with uplinks to our core switch. The ESXi host is using the 10GB switch for it's VMNetwork (2 ports - 1 on each switch) and also iSCSI traffic (4 Ports - 2 on each switch).

       

      I keep getting the alarm "network connectivity lost" on this host for the vmnic's that are doing the iSCSI data.

       

      I've searched and found about enabling Port Fast on the ports that the iSCSI taffic is using and this has not helped. I also disabled Spanning Tree as a test and this also did not help.

       

      The switches are running the latest firmware. I'm at a loss as to what else to try. The Server is using Broadcom NetXtreme II BCM57810 cards.

       

      Any help much appreciated.
