Hi all,
OK..here's the situation...we were having an ESX 3.5 host on a HP ProLiant DL580 G5. We swapped the disks to a new HP DL580G5 (as the former one was on loan). Since the change, I am not able to make the VMKernel portgroup work. Whatever NIC I attach to the vswitch that has VMKernel portgroup, its link does not come up or if it comes up, goes down and then comes back up. Its flapping!
The physical switch port is 100MB Full and I have configured the NIC to the same speed/duplex setting. But it still shows as down in VI Client and service console. The NICs are Intel PRO/1000 PT Low Profile Quad Port PCIe Gigabit Ethernet Controller.
No matter which port I use on the physical NIC or which physical NIC I use, it doesn't seem to like it. Also I tried setting speed/duplex setting using esxcfg-nics command from SC, but it does not seem to taking any effect.
Any help would be greatly appreciated!! Many thanks.
