Dell M640 Blade 'unable to connect to DHCP server LNK 0005'

Hi,

We are running a Dell M1000e Chassis and have purchased new M640 Blades, everything is ok except dhcp within the lifecycle controller.

The Drac is receiving DHCP fine but setting the network within the lifecycle controller i get the following error 'Unable to connect to DHCP server (LNK0005)' i have updated the entire systems firmware to the latest but still get the same error, the other blades in the chassis have no issue just this new m640.

Has anyone had this or can suggest steps to take to get dhcp working?

Thanks

Hello

I would start by assigning a static address to see if it is an issue with reaching the DHCP server or a link issue. Also, make sure that the network interface you are selecting for the LCC is not part of a LAG or anything else on the switch that could cause issues.

Re: Dell M640 Blade 'unable to connect to DHCP server LNK 00

Hi,

Thanks for getting back to me.

So it magically assigned an IP address with DHCP for IPv4! not sure what it was, the network interfaces aren't part of a LAG on the switch. The issue after that was it assigned the IPv4 address it then failed on the IPv6 with 'unable to save the IPv6 network settings SWC0001'. I rebooted the host and now it won't assign an IPv4 address again?

Is there anyway to disable Ipv6? would there be any reason why it assigned an ip address but then on reboot failed to assign one again? 

The network interface is not part of a LAG on the switch, and just seems intermittent on assigning an IPv4 address with DHCP?

In the IPV6 section you can set the source to static instead of DHCP, that should stop it from searching for an IPV6 address.
