HP-UX 11i v2 Installation and Update Guide, September 2006

Updating to HP-UX 11i v2
Reviewing the Update Process
Chapter 6 109
NOTE For the September 2006 release, the OnlineJFS 4.1 product is always
installed with the HP-UX 11i v2 Mission Critical Operating
Environment (MCOE) and Enterprise Operating Environment (EOE).
However, when you install the March 2006 or the June 2006 release of
the MCOE or EOE from media, you must select which OnlineJFS version
to install: 3.5 or 4.1. These versions of the product are not installed
automatically from the MCOE or EOE media.
Cold-installing or updating to the HP-UX 11i v2 September 2006 MCOE
or EOE from media will automatically install OnlineJFS 4.1and VxFS 4.1
(and EnableVXFS) due to software dependencies. To restore your system
to VxFS 3.5, and OnlineJFS 3.5, you must remove OnlineJFS 4.1 and
Base-VXFS, reboot your system, and then re-install OnlineJFS 3.5 from
the core OS media. For more information, see the IT Resource Center
