Our USS file system tends to follow the one recommended in the USS Planning Guide. When we bring up a system in our sysplex with new maintenance, the VERSION root is mounted with all its related file systems. What I noticed today though, is that our product related file systems, which are mounted off directories in '/usr/lpp', now need to be prefixed with the old VERSION root directory in order to be accessed from the updated system because they are still mounted to /usr/lpp in the old VERSION root for the other members in the sysplex. All of these products install into /usr/lpp. The USS Planning Guide recommends using /usr/lpp. So, how does one rollout maintenance in a sysplex one system at a time without disrupting the ability to access these products? I'm assuming there is a trick that I am not finding in the documentation. The only think I can think of is to change the directory location to something that hangs off of the sysplex root filesystem since these are not maintained during the z/OS maintenance process.
