Hey guys, the other night I reseated CP 0 and CMDU 0 cards due to CMDU 0 being down and disabled. Everything went well so I thought. I sync'ed the CPs memories, sync'ed the disks, performed a data RDUN which passed just fine. Verified both CPs and CMDUs up and operational as well as RDUN enabled. This morning I noticed that CMDU 0 and RDUN are disabled and out of split mode (what does that mean?). I thought during normal operation, you are out of split mode. The HWI code says to check the CMB cable. What and where is that? I did notice a graceful switchover during midnight routines from CPU 0 to CPU 1. That's when CMDU 0 dropped. Also found neither floppy drive is apparently working. CP 0 has always been active and enabled/standby. I don't suspect anything wrong with it. Any ideas?
