Installing and Configuring PPU Software

If you re-install HP-UX on a PPU system (for example, installing HP-UX 
by either cold-installing or installing from a “golden image”), you need to 
perform the following steps to restore your PPU configuration:

Step 1. Manually save your PPU configuration file by backing up the following 

file: 

/etc/ppu/ppu_config

Step 2. Install the PPU software (see “Installing PPU Software” on page 26 for 

details)

Step 3. Restore your PPU configuration file (from 

): 

/etc/ppu/ppu_config

Step 4. Start the 

ppud

 daemon (see “Manually Starting the ppud Daemon” on 

page 32 for details)

An alternative method is to: install the PPU software and configure the 
utility meter, thus starting the 

ppud

 daemon.
