Migrating a NIM client by using LPM

When Live Partition Mobility (LPM) is used to move a machine from one physical server to another and the machine is defined as a Network Installation Management (NIM) client, the NIM administrator must update the cpuid attribute for the NIM client to reflect the new hardware value after the LPM migration completes.

To update the cpuid attribute, complete the following steps:
  1. On the NIM client, acquire the new cpuid ID by running the following command:
    uname -a
  2. On the NIM master, run the following command:
    nim -o change -a cpuid=cpuid client
    Note: The OS_install network installer no longer supports the installation of the Linux® operating system because of the removal of Cluster Systems Management (CSM) support in the AIX® operating system.
