Restoring an AIX system backup from a CD or DVD

In this procedure, you restore an IBM® AIX® system backup, also called a mksysb, on a logical partition using the logical partition's optical device.

This procedure assumes that there is a Hardware Management Console (HMC) attached to the managed server.
Note: Ensure that you follow the sequence of steps for the installation method that you choose. Within each procedure, some steps are completed in AIX and some steps are completed using the HMC interface.


Before you begin this procedure, ensure that you have already used the HMC to create an AIX logical partition and partition profile with the information from Saving your existing partition profiles from a Hardware Management Console. Ensure that the AIX logical partition has the following resources assigned:
  • A device adapter attached to the optical drive
  • A network adapter
  • A hard disk with the minimum amount of space needed for AIX

Set the boot mode for this partition to be Normal mode. After you have successfully created the logical partition and partition profile, leave the logical partition in the Not activated state.

Step 1. Activate and install the partition (performed in the HMC interface)

  1. Insert the AIX system backup CD or DVD into the optical device of the AIX logical partition.
  2. Select the partition to open the menu.
  3. Select Activate. The Activate Partition menu opens with a selection of partition profiles. Ensure that the correct profile is highlighted.
  4. Select Open a terminal window or console session from the menu to open a virtual terminal (vterm) window.
  5. Select Advanced to open the Advanced options menu.
  6. Select Do not override for the Keylock position.
  7. Select Do not override for the Boot mode.
  8. Select OK to close the Advanced options menu.
  9. Select OK again. A vterm window opens for the partition.

Step 2. Select the boot device

Note: The default password for the administrator is admin.

In the SMS menu on the vterm window, complete the following steps:

  1. Press the 5 key, and then press Enter to select 5. Select Boot Options.

Repeat as many times as necessary until all the system backup volumes have been processed.

The server automatically restarts after installation is complete.

Step 4. Log in to AIX

When AIX has been successfully restored, the login prompt is displayed. Complete the following steps:
