We were able to resolve the problem. Initially our SAN admin believed it was a bad component on the switch (some sort of adapter) and that was replaced. It seemed to improve the connectivity but after a while we would still have the LUN path disconnects.
device-mapper: multipath service-time: version 0.2.0 loaded sd 0:0:0:7: [sdj] Medium access timeout failure. Offlining disk! sd 0:0:0:7: [sdj] Result: hostbyte=DID_TIME_OUT driverbyte=DRIVER_OK sd 0:0:0:7: [sdj] CDB: Read(10): 28 00 02 90 18 00 00 00 08 00 end_request: I/O error, dev sdj, sector 42997760 We ended up putting the chpid offline and then online and that cleared up the problem. I would assume that it reset the channel in some fashion. So far so good. Thanks for all your help!

This is enough to cause the channels to refresh their addressing information. Part of this process is re-logging in. Also, it clearly states that all zoning information will be lost. It has some steps for backing it up and restoring it. I'm not surprised that Chris is having problems. I hope you figure things out without too much more trouble!
