Operating System Support - IBM Power 570 Technical Overview And Introduction

Redundant Service Processor connectivity
Redundant Service Processor function for managing the service processors when one fails is
supported on all systems that are operating with system firmware level FM320_xxx_xxx, or
later. This support is available for configurations with two or more CEC enclosures.
Redundant Service Processor function requires that the Hardware Management Console
(HMC) be attached to the Service Interface Card in both CEC enclosure 1 and CEC
enclosure 2. The Service Interface Card in these two enclosures must be connected using an
external Power Control cable (FC 6006 or similar). Figure 2-25 shows a redundant HMC and
redundant service processor connectivity configuration.
Figure 2-25 Redundant HMC connection and Redundant Service Processor configuration
In a configuration with multiple systems or HMC's, the customer is required to provide
switches or hubs to connect each HMC to the appropriate Service Interface Cards in each
system. One HMC should connect to the port labeled as HMC Port 1 on the first 2 CEC
drawers of each system, and a second HMC should be attached to HMC Port 2 on the first 2
CEC drawers of each system. This provides redundancy both for the HMCs and the service
processors.
For more details about redundant HMCs, refer to the Hardware Management Console V7
Handbook, SG24-7491.
