MSA1000 connection Issues

Good Day, I hope I'm posting to the right area.  I have a Microsoft 4 node cluster running 2003 server.  The servers are DL380 G5 and I have one MSA1000 Raid.  My problem is 2 of the servers have lost connection to the MSA.  I ran the ACU and the MSA is missing Node A and B, nodes C and D are fine.  I have replaced the following: both FC cards on the DL's the Transceivers on the MSA and tried a new Fiber cable.  Also replaced the 8 port FC switch still no luck.  Now on Node B if I restart the server I can connect to the MSA this will last for about 1 to two hours and then it it lost.  I ran the ACU diagnostics when I was connect and it show  OK, When it was gone it shows error MSA not connected.  What makes this really hard, it is at a remote site (white Horse and the Tech there is not a lover of HP)  I really need help not sure where to go next.  I have a system here in Ottawa that I can pull the Controller out of the MSA If need be.
