All,
Having a problem with DMP not disabling a controller once the pathway is
gone. To simulate a controller failures I merely unplug the cable providing
the secondary pathway to the array. I see errors from the sd and jfca
driver, but I never see the "dmp disable " message until AFTER I plug the
cable back in. While the cable is unplugged the following return
"positive" results
vxdisk path --> shows all pathways enabled
vxdmpadm getsubpaths dmpnodename=<one of the dmp devices> --> shows all
pathways "ENABLED".
Now, after plugging the cable back in I immediately see the "dmp disabled"
for the pathway message, and if i run the two commands again I now see the
pathways "DISABLED". After a few seconds dmp reenables the paths and all is
fine.

An interesting note here. When NODE(1) is master and I unplug the cable on
it vxconfigd dies thus causing the cluster monitoring to die. vxconfigd
isn't started again until I reconnect the cable.
Anyone out there have any similar experiences? My thought is that the jfca
driver isn't letting dmp know that the pathway is gone...it's as if the
driver gets locked up. I'm going to install rev 10 of the JNI/JFCA patch
and see if that helps.
Please shout if you have any suggestions.
