Booting the system

This procedure completes the system boot phase.

1. The init process starts phase 2 running of the rc.boot script. Phase 2 of rc.boot includes the following steps:
   1. Call the ipl_varyon program to vary on the rootvg volume group.
   2. Mount the hard disk file systems onto their normal mount points.
   3. Run the swapon program to start paging.
   4. Copy the customized data from the ODM database in the RAM file system to the ODM database in the hard disk file system.
   5. Exit the rc.boot script.
2. After phase 2 of the rc.boot script is complete, the boot process switches from the RAM file system to the file systems that are stored on the hard disk.
3. Then the init process runs the processes defined by records in the /etc/inittab file. One of the instructions in the /etc/inittab file runs phase 3 of the rc.boot script, which includes the following steps:
   1. Mount the /tmp hard disk file system.
   2. Start the configuration manager phase 2 to configure all remaining devices.
   3. Use the savebase command to save the customized data to the boot logical volume.
   4. Exit the rc.boot script.
