    RAS and manageability Chapter 3. This chapter provides information about IBM System p5 design features that help lower the total cost of ownership (TCO). IBM reliability, availability, and service (RAS) technology allow you to improve your TCO architecture by reducing unplanned down time. This chapter includes several features based on the benefits that are available when you use AIX 5L.

    IBM System p5 systems in more detail. 3.1.1 Fault avoidance IBM System p5 servers are built on a quality-based design that is intended to keep errors from happening. This design includes the following features: Reduced power consumption and cooler operating temperatures for increased reliability,...

    Figure 3-1 Schematic of Fault Isolation Register implementation The FIRs are important because they enable an error to be uniquely identified, thus enabling the appropriate action to be taken. Appropriate actions might include such things as a bus retry, ECC correction, or system firmware recovery routines. Recovery routines can include dynamic deallocation of potentially failing components.

    3.1.5 N+1 redundancy The use of redundant parts allows the p5-520 and p5-520Q to remain operational with full resources: Redundant spare memory bits in L1, L2, L3, and main memory Redundant fans Redundant power supplies (optional) Note: With this optional feature, every deskside or rack-mounted p5-520 or p5-520Q requires two power cords, which are not included in the base order.

    The p5-520 and p5-520Q are designed for client setup of the machine and for the subsequent addition of most hardware features. The p5-520 and p5-520Q also allow clients to replace service parts (Client Replaceable Unit). To accomplish this, the p5-520 or p5-520Q provides IBM System p5 520 and 520Q Technical Overview and Introduction...

    – This concurrent maintenance task requires HMC-guided support. 3.2 Manageability We describe the functions and tools provided for IBM System p5 servers to ease management in the next sections. 3.2.1 Service processor The service processor (SP) is always working. CEC can be in the following states:...

    Note: The IBM System p5 service processor enables the analysis of a system that does not boot. It can be performed either from ASMI, an HMC, or an ASCI console (depending on the presence of an HMC).

  • Page 99: Service Agent

    Service Agent is an application program that operates on an IBM System p server and monitors the server for hardware errors. It reports detected errors, assuming they meet certain criteria for severity, to IBM for service with no intervention. It is an enhanced version of Service Director™ with a graphical user interface.
  • Page 100 Figure 3-3 shows possible communication paths for an IBM System p5 server that is configured to use all the features of Service Agent. In this figure, communication to IBM support can be through either a modem or the network. If an HMC is present, Service Agent is an integral part of the HMC and, if activated, collects hardware-related information and error messages about the entire system and partitions.

    You can configure the HMC to use the Service Agent call-home feature to send IBM event information. Service Focal Point is available also in Integrated Virtualization Manager. It allows you to manage serviceable events, create serviceable events, manage dumps, and collect vital product data (VPD), but no reporting through Service Agent is possible.
