IP address service processors

With POWER6, the default addresses of the service processors have changed. This only applies to environments where the managed system was powered on before the HMC was configured to act as an DHCP server. The Service Processors may get their IP-Addresses by three different mechanisms:

  1. Addresses received from a DHCP Server.
  2. Fixed addresses given to the interfaces using the ASMI.
  3. Default addresses if neither of the possibilities above is used.
The default addresses are different betweeen POWER5 and POWER6 servers. With POWER5 we have the following addresses:
Port HMC1: 192.168.2.147/24
Port HMC2: 192.168.3.147/24
The POWER6 systems use the following addresses:
First Service Processor:
Port HMC1: 169.254.2.147/24
Port HMC2: 169.254.3.147/24

Second Service Processor:
Port HMC1: 169.254.2.146/24
Port HMC2: 169.254.3.146/24
