Rebuilding the standby BOS boot image

The rebuild boot image operation, using the -B flag, enables you to rebuild the standby BOS boot image.

The new boot image will be based on standby BOS system files and written to the standby BLV. The multibos build boot image operation performs the following steps:

  1. The standby BOS file systems are mounted, if they are not already.
  2. The standby boot image is created and written to the standby BLV using the AIX® bosboot command.
  3. If the standby BOS file systems were mounted in step 1, they are unmounted.

Automatic file system expansion

The multibos -X flag auto-expansion feature allows for automatic file system expansion, if space is necessary to perform multibos-related tasks. You should execute all multibos operations with this flag.
