DL 385 G2 Network device name issue

Sudeesh — Sun, 14 Dec 2008 06:34:53 GMT

Hi All,

I have installed RHEL 5.2 x86_64 on a proline DL 385 G2 and getting some issue with network interface device names.

System got both Intel and Broadcom NICs. In each reboot they get diffrent device names assigned. How to set the driver to assign a fixed device name every time?

I have dowloaded latest driver from HP and installed them.

Your help will be much appreciated.

Thanks

Sudeesh

Shalom Sudeesh,

This will probably be corrected by upgrading the firmware of the system.

I thought the DL385 G2 would not take a 64 bit OS. You might want to check the support matrix on this. I know the G2 DL360 won't take 64 bit OS.

The OS could be a contributing to the problem.

You can use udev to assign permanent names for network cards - http://reactivated.net/writing_udev_rules.html#example-netif

Check the firmware then and try Ivan's procedure.

I could finally fix the issue with putting entries in /etc/modprobe.conf and specifying HWADDR in /etc/sysconfig/network-scripts/ifcfg-eth# files.

alias eth? bnx2 .. for each NIC
alias eth? e1000e

I have another issue trying to add VIP for the load balancer. The system becomes unreachable from network after adding the VIP lo:1.

Any idea what is causing this?

Even the DL385 (original, so G1) is an opteron box thus taking a 64-bit OS which won't even boot unless the box can run it. I have one running debian-amd64 doing my database work.

Anyhoo, is udev installed? It will keep nic assignments constant based on their MAC address. (Which is very interesting if you have autogenerated MAC addresses in a VM...)

Team,

All issues solved. I got a doc from net on how to set the VIPS for load balancer and disabling arp ... n all those stuff.

Thank you very much for your response.
