I have a mixed-interconnect VAX cluster with 8800, 785, 6240 and VAXStation 3100s. The disks are connect to the star coupler with two HSC 70-s, all dual-ported. VMS version is 5.3-1. A few tape drives, too. I want to know if I can add another 785 to the star coupler, and a disk to the HSCs, and run ULTRIX on it? If so exactly how do I go about it, making sure that the existing VMS cluster does not get confused. There is no requirement that the VMS and ULTRIX systems actually share disks. They will be on the same ethernet.

We found the hard way that disks could become corrupt just by mounting them on two indpendent clusters at the same time. It was not necessary for any transactions to occure on either system. If I were going to attempt VMS and ULTRIX on the same CI, I think I would set the ULTRIX device /noavaliable on the VMS system and remove the device special files for the VMS disks from the ULTRIX system. --Bill Braden (Measurex Inc.)
