Update to Broadcom NIC Dropping out on Solaris issue

Update to Broadcom NIC

Update 2010-07-01: Sun got back to one of the blog commenters regarding the issue with Broadcom NICs dropping out on HP servers and stated the issue relates to the HP supplied Broadcom drivers, and Sun recommended using these. So HP people may be seeing a different issue. Please see this blog comment for details. Many thanks for passing this information on Daniel!.

BREAKING NEWS – 2010-06-25 11:30 BST (GMT+1): I’ve just spoken with a chap called mui on #opensolaris on irc.freenode.net who reports that this issue relates to “C States”. Disabling “C States” in the BIOS (It’s in “Processor Settings” on Dell boxes) supposedly will work-around the issue. C States support was added in Solaris 10 update 8, so this is probably why our Solaris 10 update 7 boxes are unaffected.

Supposedly Sun/Oracle have a patch internally they can supply to you for Solaris 10 if you have a support contract. If you’re on OpenSolaris, Mui has made this package available that works with snv_134. DISCLAIMER: Please test this prior to putting it into production as it’s provided with no warranty. Alternatively you might be able to grab the latest 6.0.1 BNX driver from the on-closed-bins.i386.tar.bz2 package on the OpenSolaris website.

Here’s the rest of the (now somewhat out of date) post…

Right, I have an update on the Broadcom NIC issue.

It seems the BIOS was a bit of a red herring, the Broadcom FW is completely independent of the system BIOS and downgrading this doesn’t change the Broadcom FW version. Pretty obvious really – I have no idea where I read that the two were linked.

Anyway, I did find a broadcom firmware tool called lnxfwnx2 which Dell distributes in the Broadcom firmware update packages. It’s a Linux tool and it lets you save out/restore firmware from Broadcom NICs.

Unfortunately I couldn’t find 4.x.x Firmware releases for the card, only 5.x.x releases. It’s highly frustrating Broadcom don’t provide these things directly.

However we have two Dell R410 boxes running Solaris 10 update 7 which have been running for over 200 days and never had any network issues at all. They have the 4.6.4 firmware on them. I am planning on taking one of these out of service, saving out the Broadcom firmware with the tool, and then loading this firmware onto the new misbehaving Dells.

I’ll also copy across the same BRCMbnx driver package from the boxes that haven’t had any issues as well. I’m also planning on putting the same Dell System BIOS on the new machines as the working ones. This way the Broadcom FWs will match, the System BIOS will match, and the Drivers will match. The only difference will be Solaris 10 update 7 vs Solaris 10 update 8.

We can then see if the new boxes behave themselves…

The Dell package is here: ftp://ftp.us.dell.com/network/NETW_FRMW_LX_R259547.BIN

I couldn’t get it to run on Ubuntu/Debian based distros, but it runs fine on the CentOS 5 32bit live CD:


Once you’ve booted the LiveCD, configure the network, then do:

# wget ftp://ftp.us.dell.com/network/NETW_FRMW_LX_R259547.BIN
# chmod 755 NETW_FRMW_LX_R259547.BIN
# ./NETW_FRMW_LX_R259547.BIN --extract r259
# cd r259
# ./lnxfwnx2

It’s an interactive tool and you can type “help” to get a list of commands.

Here’s an example of saving/restoring:

0> dumpnvram nic-fw-backup.bin
0> restorenvram new-nic-frmw.bin

I got these instructions from here. It’s also possible saving the NVRAM will save all options, including the MAC address, so double check this when restoring the NVRAM on a different machine.

It also looks like the DOS based diagnostics ISO from Broadcom’s website has a similar tool called uxdiag.exe which can program the firmware and turn various features of the card on/off (such as WOL (Wake on LAN), the ‘mba’ (MultiBoot Agemt), the ‘management firmware’ (Still don’t know what this does). You can get the iso from:


The boot menu gives the option “Install FreeDOS to harddisk” which is the option you want – you can opt later on not to do this but to run FreeDOS from the CD. A bit confusing. The uxdiag tool has a manual here.

I also spotted this thread on forums.sun.com which suggests a lot of HP people are having the same issue, irrespective of the FW version. So it remains to be seen what the root cause actually is.
