To update just the PPU software on one or more partitions,
you do not need to do anything special to preserve the PPU configuration.
Simply follow the installation instructions from “Installing
PPU Software” for your appropriate platform
(HP-UX or Windows). (On HP-UX, if you happen to be reinstalling
the same PPU version as was previously installed, perhaps to ensure
a clean installation, you may need to include the option -x reinstall=true on the swinstall command to force a new installation.)
However, if you reinstall HP-UX or Windows on a partition
(for example, installing HP-UX by either cold-installing or installing
from a “golden image”), you need to perform the
following steps to preserve your PPU configuration:
Before reinstalling,
execute the ppuconfig command and record the configuration information (utility
meter, system identifier, and core information) from the output.
Reinstall HP-UX or Windows on
the partition and install the PPU software. (See “Installing
PPU Software” for details.)
Using the recorded output from
Step 1, configure the PPU settings with the ppuconfig command. (See “Configuring
PPU Software ” for details.)
