Jack,

We were having the problem only on one partition, thus far.

Do you notice it on all your partitions or just certain ones.

Well you have discovered the Achilles heal of the HEA. The card sits
on
the Primary System (GS) Bus so it cannot be hot swapped, added, or
removed. Thus there is no option from the HMC to stop it or start it
either. I hope someone knows a trick that I do not but I think the
only
way to reset that card is to power the system off and back on.

Now, that said, that simply should NOT be required. I would ABSOLUTELY
pursue this with IBM SUpport. That card is the defacto Ethernet on all
POWER6 and POWER7 servers and if there are issues with the card or
drivers this needs to be addressed 'with quickness'.

We are using HEA along with the 5706 for important partitions using

with load balancing.



One of the HEA's are reporting lots of retransmissions causing
performance problems.



We took the HEA interface down and the performance problems clear
up.



So how do we go about resetting the HEA port or card?



Is there a command on the OS or some thing on the HMC?



TIA,
