Requirements for Live Partition Mobility with HEA

Edit online

Before you can start using LPM with HEA, you must make sure that your system environment meets configuration and access requirements.

Partition requirements
  • The CEC source and CEC target must be capable for partition migration.
  • The source AIX LPAR must not have any physical resources with the setting Required in its profile.
  • The source AIX LPAR must not have any physical resources besides a HEA.
Access requirements
  • You must have root authority on the partition that you want to migrate.
  • You must have hscroot authority or equivalent authority required for partition migration on the source HMC and destination HMC.
Configuration requirements
  • HEA must not have the Required setting in the partition profile, but it can have the Desired setting in the profile.
  • All HEA must be configured under EtherChannel as primary adapters.
  • All primary adapters in EtherChannel must be HEA.
  • The backup adapter for EtherChannel must be a Virtual Ethernet adapter.
  • A minimum of one EtherChannel must be configured with HEA as a primary adapter and Virtual Ethernet adapter as a backup adapter.
  • A maximum of four EtherChannel is supported.
  • EtherChannel failover must be functional.
  • You must verify that both the source system and target system are set up for partition migration.
  • If you are migrating between two HMCs, you must set up SSH authentication between the source HMC and remote HMC. You must run the mkauthkeys command on the source HMC before you start the migration.
