I am trying to setup a FC port-channel between a UCS and N5k. Environment is UCS 2.0(3c), 6248s, 5548s, EMC VNX 5300. When I leave the FC uplinks out of the port channel they
Hi There, We have one Failover Cluster for Hyper-V VMs running on Windows Server 2012R2. Everything working well but one thing. Today, I try to
Clear the high BR by cleaning the fiber and port, and reconnect the fiber to the port. When BR is at acceptable levels, the system triggers Raman tuning and turns the Raman pumps on
Help with fibre-channel issue after IP mess-up So late last week I was being dumb and was changing some vlan assignments on my HP ProCurve 5406ZL switch. I accidentally added two ports as
For each of these combinations, first a warning event, and then an alarm event can be generated at the respective endpoint (for example, temperature-low-warning, current-high-alarm, and so on).
This message occurs when the Fibre Channel fabric cannot successfully complete a Name Server query issued to obtain configuration and device information when an adapter is connected to the Fibre
