ProLiant BL460c Gen8 is not able to get IP address from remote DHCP server

[JOSE_M]

Hi,

we need to install SLES12 in several BL460c Gen8 by using PXE/DHCP configured in a remote jumpstart server. The server is perfectly working for other type of server.

I can see the DHCPDISCOVER and DHCPOFFER for the blade mac address in the server /var/log/messages, but not the DHCPACK and sucesive, so the blade (dhcp client) does't get IP address. 

If I force the blade to boot over DHCP, the messages that it shows are:

dhcpcd[4003]: eth0: timed out
dhcpcd[4003]: eth0: trying to use old lease in `/var/lib/dhcpcd/dhcpcd-eth0.info'
dhcpcd[4003]: eth0: broadcasting for a lease

Please, help!!!

Finally resolved by myself, issues with the tags, concretly I have added the untagged port (Bay1 x6) directly in the Ethernet Network without create a Shared Uplink before.

BR,
