With the VAX 8550 cluster we were able during testing to run with two nodes on the operational ethernet and the third machine on a test rail ethernet. Since the VAX 4705A uses the ethernet for CI traffic, this has not worked too well. I was wondering if it would be possible to add a single ethernet card to the test machine and then set it up so that ethernet traffic uses one ethernet controller and the Cluster traffic uses the other ethernet. Hopefully so that could then switch the DECnet ethernet contoller without worrying about changing anything in the system software. VAX VMS Ver 6.2. Our only other choice seems to be to boot the machine standalone and access only some of the cluster disks. I am very afraid someone will take the opportunity to Mount a cluster disk and destroy operations. Art McClinton (703)610-1716

Your question is somewhat ambiguous -- without knowing more, you will need to set VAXCLUSTER=0 and NISCS_LOAD_PEA0=0, and reboot the system standalone. It is possible to have two Ethernet controllers in the system as long as the LANs are disjoint, or as long as they are connected by routers only (no bridges), or as long as DECnet (Phase IV) is not started on both controllers. (DECnet-Plus supports multiple Ethernet controllers on the same LAN, or extended or bridged LAN.) It is possible to program the `primary' system to run as a member of the VMScluster (with a local or served system disk) and to ignore the secondary Ethernet controller, and to use a `secondary' (local) system disk to reboot access the test Ethernet network, and ignore the primary Ethernet. One can not and should not attempt to access a shared VMScluster disk unless the node is a full member of the VMScluster. Severe corruptions can arise otherwise. | |||||
