Try the event emulation facility in HACMP:
smit swap_adapter.dialog

I'm don't want to perform a test. We are in the middle of the
production day. I want to move the IP address from one NIC to another,
with as little impact on the users as possible.
We are having some performance problems with the boot/service NIC in my
cluster. I have nothing in errpt about it but, at the switch we are
seeing a ton of "FCS" errors (don't really know what that it) The
symptoms are horrible up stream (to the NIC) speed. Down stream hauls
a**. We've verified duplex and speed settings on all equipment. Next
test is to cable to a different port on the switch. If the behavior
still exists I'm going to want to take the boot/service NIC out of the
picture. I'm looking for the gentlest manner in which I can do this

Yes, but you'd be watching a true take-over, rather than a manual
transfer-of-power ... It'd be a truer test of the software's proper
operation.

That would work but would still be a bit disruptive. HACMP would have
to determine that the NIC is no longer working and then move the address
over. I'd like to tell HACMP to do it nicely.

Would
ifconfig enX down
work?
