I have been seeing an issue in my virtual environment of randomly losing connectivity to iSCSI LUNs. My hosts are showing a loss of connectivity, I looked at the logs on my X670V-48t and i found what looked to be the same time frame of the port going down stating :
05/22/2016 19:23:28.19 [i] Slot-1: Port 1:21 link down - Local fault
05/22/2016 19:23:57.64 [i] Slot-1: Port 1:21 link UP at speed 10 Gbps and full-duplex
05/22/2016 19:23:58.99 Slot-1: Configuration mismatch detected by DCBX (Baseline v1.01) for the PFC TLV on port 1:21.
05/22/2016 19:23:59.99 Slot-1: Configuration mismatch resolved by DCBX (Baseline v1.01) for the PFC TLV on port 1:21.
I need a little insight on what is possibly going on here.
