Hi, We do have some errors appearing on the new ZCPs we've recentlly integrated to replace old CP40s. These errors seem to be related to a loss of fault tolerance and shadow between primary and secondary CP. It's appearing on the two ZCPs. Some of the logs we can see in the sysmon are the following: 2008-04-23 01:53:32 CP3060 Fault Tolerant Exec SM_MSG -00047 Fault Tolerant Prim Module Now Single. ROM Addr 00006C1C0380 2008-04-23 01:53:35 CP3060 Process = WDT_TASK FTFCPS 000033 FT state in unexpected state to continue ROM Addr 00006C1C0357 2008-04-23 01:53:45 CP3060 Fault Tolerant Exec SM_MSG -00046 Fault Tolerant Modules Now Married 2008-04-23 01:53:45 CP3060 Process = Shadow Report RDHSS 000130 - Operator Initiated Reboot 2008-04-23 01:54:58 CP3060 Fault Tolerant Exec SM_MSG -00047 Fault Tolerant Prim Module Now Single.
