Xenserver 6.1 not applying Driver update properly

Good morning,
We are running a small Xenserver pool (2 hosts) using identical Dell PowerEdge 2970 servers. We are using embedded NICs (Broadcom 5708's) for management traffic (with additional Intel dual Gig nics for iSCSI).

We are currently on Broadcom driver v 2.2.1j (i.e. bnx2-2.2.1j), and trying to update to comply with hotfix requirements and maximize performance. I'm not a XenServer / Linux wiz, but using guides, I have been working on this for a few hours without success.

I found the current version by running

modinfo -F version bnx2
OUTPUT: 2.2.1j

Also (per other suggestions), I confirmed that the updated driver was required/suggested per compatibility with recent hotfixes, by running

lsmod | egrep 'bnx2x|bnx2|tg3|cxgb3|cxgb4'
(suggested at this link, http://xendesktopguy.com/2013/04/18/xenserver-6-0-2-hotfix-and-driver-disk-install-summary/)
OUTPUT: bnx2                  192638  0


Following Citrix instructions (from http://support.citrix.com/article/CTX138040), I've downloaded the driver bnx2-2.78.11 and installed it per the instructions. Installation says it completes.
OUTPUT: Installing 'Broadcom bnx2 driver'...
Memory required by all installed packages: 884998144
Truncating to static-max: 780140544
Setting VM.memory_target: 780140544
Pack installation successful.

Post install, MODINFO returns the old version (2.2.1j), and lsmod the same. I reboot the host, nothing changes.

This has been performed on both hosts in the pool (first the master, then the slave) - identical results.


What am I missing?

Thanks!

Did you install any hotfixes to your xenserver 6.1?

Kernel modules are compiled for a specific linux kernel. Some Hotfixes renew the kernel and requires driver disks to be updated too.
Here are some links to newer driver packs
since XS61E030 http://support.citrix.com/article/CTX138563
since XS61E018 http://support.citrix.com/article/CTX137629
since XS61E014 http://support.citrix.com/article/CTX136622

You can see your installed hotfixes as sorted list using this command:
xe patch-list hosts:contains=$(xe host-list hostname=$(hostname -s) params=uuid --minimal) params=name-label | sort -u
... or use xencenter, of course.

Yes, all of these are installed.

Seems like you nailed it! I was confused because the driver versions didn't match up, but I see on the XS61E030 driver pack page that it referenced an identical bnx2 driver version - seems that they just relabeled or repackaged it for this latest hotfix.

I downloaded and installed that driver version, and it took the way I expected it to - thanks so much!!
