Proliant BL460c G6 in a C7000 G2 network MAC address issue

Hi all,

 

Last week i had a problem with one of the blade servers on the enclosure, as i had a spare one, i´ve just swapped the hard drives on the servers and had the system up and running very quick.

 

The system works ok but i have an issue with the MAC Address of the NIC:

 

In the ONBOARD Admin website the old blade server has MAC ADDRESS A assigned to NIC 2.

The new server has MAC ADDRESS B and MAC ADDRESS C assign to NIC 1 and NIC 2.

When i ping the IP address of the new server it answers ok but if i take a look at the ARP cache it points to MAC ADDRESS A instead B or C. I´ve tried to clear the arp cache without success on the operating system (windows server 2008).

 

Well, the problem comes when i switch on the faulty old blade to perform some tests. Both servers works fine but pinging the new one from time to time have lost packets.

 

Any idea on how to get the MACs assigned correctly?

 

Thanks

Hey,

Are they same even if you look in 'ipconfig /all' ?
Do you have virtual connect?

Hi,

 

Yup, the MAC shown doing an ipconfig /all is the same (Mac Address A). The blades are configured with Virtual Connect.

 

The server profile has the following configuration:

-----------------

Port:1

Network Name: Unassigned

Port Speed: Preferred

Allocated Bwidth: 1 GB

PSE: Use Bios

MAC: HW-DEFAULTS

Mapping: LOM1=>Bay 1

------------------------

 

 

Thanks

Re: Proliant BL460c G6 in a C7000 G2 network MAC address issue

Could you do something with the VC profile then or on the server?
I am not so sure what the different MAC settings on the profile does.

Maybe re-create the profile is a good idea?

The profile says you are using HW-Defaults for the MAC, is that true? If so it's pulling the MAC from the physical server, not from the software. To have MAC and WWN's independent of the hardware you need to have the VC's (or VCEM) manage those.

Yeah that's what's curious. If it's up to the server, then you'd have to set the MAC manually on each server for them to be the same, right?

Either that or use the VC with the custom range and put that MAC in the custom range.

Are you using the HP Network Control Utility to team the NICs? As the Teaming software takes the MAC address of one of the NICs an uses it for the "Team NIC". And i don't know if it will update itself if it comes to a new server.
