Network Uplink Redundancy Lost

[scotty_p]

I have 3 ESX 4.0 servers in a cluster and one of them is reporting "Network Uplink Redundancy Lost". 2 NICs one the server are configured as a DMZ vswitch. One of the NIC's (vmnic6) "Observed IP Ranges" under Configuration\Network Adapters is showing up as "None". vmnic6 and vmnic7 are configured as an aggregate on our switch and they're both in the DMZ VLAN. For some reason 7 is showing up with the correct subnet range, but 6 shows up as none. I've unplugged the cable to the NIC, removed vmnic6 from the vswitch and readded it and tried disabling and reenabling the NIC. It is still coiming up as "None" under "Observed IP Ranges". Does anyone have any ideas how to correct this?

Thanks

Which team policy are you using?

On physical switch side do you have some error?

Have you alredy tried to change the cable?

The NIC Teaming policy is "Route Based on IP Hash". I eventually cleared the alarm and it never came back. This is the second time we've seen this. Not sure why it's happening, but it's clear now. I'll just have to keep an eye on it.

Thanks,

"Route Based on IP Hash".

Have you configured properly the switches for this?

I suggest to start with the default Team policy (Port ID) and check if the issue is solved.

OK. I'll give it a shot. Thanks.
