Standalone System or NFS Cluster Server on
NCR UNIX SVR4
In general, stand-alone systems are treated as cluster servers. The
cluster server exports the /opt file system with read-only permissions.
ITO software is located on /opt/OV path, with the same logical and
physical path names.
NOTE By default NCR UNIX does not export the /opt file system. ITO cluster
operations can only be enabled by manually exporting the /opt file
system on one NCR system and then mounting it from one or more NCR
systems. This manual cluster setup must be done before the ITO
installation process in order to have an impact on the ITO installation.
NFS Cluster Client on NCR UNIX SVR4
NCR UNIX cluster clients are those NCR UNIX systems that have /opt
file system NFS mounted. Their cluster server is the system to which
/opt is mounted and must also be a system running NCR UNIX.
