Nice try, but it's still sick. Hmmmm.

In fact, I have never seen this kind of behavior with any of the 6.xx
firmwares. So I do not anticipate that an upgrade would solve the
issue. However, if you have the will and the means you can go ahead
and try a new firmware. It may also prove to be helpful if you are
willing to escalate the problem to IBM since they always insist on
using the newest version available.

Good, good. If all else fails you may want to rewire the config for a
minute, just to make some tests. Try to attach the FAStT directly to
your FC adapters (F/C 6239, I assume) and see if it solves the issue.
Other than that, you can still check the microcode on the adapters and
the level of AIX drivers (devices.fcp.disk.rte and
devices.fcp.disk.array.rte). I have no other ideas.
Check the connections. Unplug the LC connectors and check them, you
should see red light coming out of both connectors (one wire per
connector, of course).
