Operating 9.x and 10.x Systems Together

HP has provided tools and procedures to help you to continue to operate 9.x and 10.x systems together, sharing peripherals, NFS mounts, etc., as you did when all the systems were running 9.x. For more information, see the HP-UX 9.x/10.x Interoperability Guide (HP part number 5963-8920), supplied in the same "Upgrade Tools" package that includes the manual you are reading.

HP-UX 10.x systems lend themselves particularly well to operating with systems running other versions of HP-UX. For example, you can mount "non-system" directories (directories that do not form part of HP-UX itself) from 9.x systems onto a 10.x system; you can do this either by means of NFS mounts, or you can actually move non-system disks from HP-UX 9.x to 10.x systems (but Series 700 Software Disk Striping is not supported on 10.x; see “Considerations for Series 700s ”). In addition, if you configure NFS Diskless on the 10.x system, you can swap dynamically to any system, including a 9.x system.

These characteristics mean not only that 10.x systems communicate easily with 9.x systems, but also that you may be able to save disk space on your 10.x systems by sharing "non-system" 9.x disks.

10.01 User Login Scripts

Files such as /etc/profile supplied on 10.01 systems contain code that checks to see if these scripts are running on a 9.x or a 10.x system, and takes appropriate action (setting the PATH variable differently, for example).

For more information, see Chapter 6 of the HP-UX 9.x/10.x Interoperability Guide.
