Restoring VxFS 3.5 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 Web site:
