HP Field service has swapped the 4 single port Nic's for 2 dual port ones. 1
fibre, 1 gigabit. Some 3rd level support guy put an entry in the call log,
that this is a know issue, and to replace with dual port nic's. I'm trying
to get more details on exactly what the issue is.
Removed to old nic's from the teaming, added the new dual port ones to the
teaming, rebooted, everythings working fine. all 4 nic's are connected and
traffic is flowing on all 4 links. Quite happily fails over to the other
link when 1 is unplugged, and will switch back and forth.
Now the client is not happy, they see this as 2 single nic's and that they
have lost redundancy, and they now have 2 single points of failure, which is
probably partially true.

If it is working when cords are unplugged, it is getting confused about
which route to take, so look at your teaming settings first.
I don't have one handy to look at, but I recall there being a few different
ways to set up the teaming. I had mine set up to use the same MAC, same IP,
but I don't recall what setting I used for load-balancing (I think it was
fail-over).
You also need to set the same style of load-balancing on the device it is
plugged into.

NLB is definately disabled.
The setup is currently running fine in production with 2 nic's unplugged,
but I have been left with the task of solving the issue.

ISA doesn't know or care about teaming, Q-tagging or any other layer-2
protocols.
Make sure you don't also have NLB enabled, as NLB and teaming is not a
supported combination.

Hi,
Currently working on a brand new server, it a new HP proliant, quadriple
nic'ed.
It's running W3KR2 with all updates to date applied, domain member, all
HP updates for the HP software applied, nic's have the latest firmware
applied. it's using the HP server nic teaming software. ISA2004
installed with all updates to date applied.
The Internet connection use 2 gigabit nic's teamed to connect to a 56M
frame relay connection via a watchguard firewall (Let's not get into the
watchguard discussion, I have to work with what the company has in
place) , via cat5e cable.
They are 4 separate nic's and not dual ported ones.
The LAN connection uses 2 fibre channel nic's teamed to go to a dual
redundant cisco switch.
Before ISA was installed, teaming was working fine, both the internet
and the lan were accessable.
After installing ISA, neither the internet or the LAN is accessable,
unless 1 of the teamed nic's is unplugged on both sides. i.e. 1 internet
nic unplugged + 1 lan nic unplugged eerything works like a dream.
But plug either or both of the 2 that were unplugged in, and neither the
internet nor the LAN is accessable.
Disable the firewall services, and reboot, everything is fine with all 4
NIC's plugged in.
HP field service have been twice out replaced the nic's, ran diag's and
they are pointing the finger at the ISA server. Saying it's not
compatable with the HP nic teaming software, but can not point out any
documentation to support this. Searching the internet also drew a blank.
The company configured the server using the proliant configurader, so I
am assuming that everything is compatable, and the field service people
responded in the afermative, when asked is everything compatable.
Does anyone have any experience or suggestions on this ??
Glenn
