Creating a boot image on a boot logical volume

If the base operating system is being installed (either a new installation or an update), the bosboot command is called to place the boot image on the boot logical volume. The boot logical volume is a physically contiguous area on the disk created through the Logical Volume Manager (LVM) during installation.

For a list of prerequisites for this procedure, see Creating boot images.

The bosboot command does the following:

  1. Checks the file system to see if there is enough room to create the boot image.
  2. Creates a RAM file system using the mkfs command and a prototype file.
  3. Calls the mkboot command, which merges the kernel and the RAM file system into a boot image.
  4. Writes the boot image to the boot logical volume.
To create a boot image on the default boot logical volume on the fixed disk, type the following at a command prompt:
bosboot -a
bosboot -ad /dev/ipldevice
Note: Do not reboot the machine if the bosboot command fails while creating a boot image. Resolve the problem and run the bosboot command to successful completion.

You must reboot the system for the new boot image to be available for use.
