After transitioning a SAN boot LUN on an AIX host with an FC or FCoE configuration, you must perform certain steps to boot your host from the SAN boot LUN.

For copy-based transitions, you must perform these steps after completing the Storage Cutover operation in the 7-Mode Transition Tool. Copy-free transitions are not supported on AIX hosts.

  1. Log in to the Hardware Management Console (HMC), and then boot your host in the SMS menu.

  2. Select the host.

  3. Select Operations > Activate > Profile.

  4. Click the Advanced tab.

  5. Select SMS, and then click OK.

  7. Enter 1 to select 1. Select Install/Boot Device.

  8. Enter 5 to select 5. List all Devices.

  9. Enter the device number of the ONTAP SAN boot LUN that you want to boot with.
