    Management (included with Virtual I/O Server software version 1.2 or later). There is only one pool of shared processors at the time of the writing of this IBM Redbook and all shared partitions are dispatched by Hypervisor within this pool. Dedicated partitions and Micro-partitions can coexist on the same POWER5+ processor-based server as long as enough processors are available.
  • Page 67 Some additional information related to the virtual processors: There is one-to-one mapping of running virtual processors to physical processors at any given time. No more virtual processors can be active at any given time than the total number of physical processors in a shared processor pool. A virtual processor can be either running (dispatched) on a physical processor or on standby and waiting for a physical processor to became available.

  • Page 89 The remote HMC and the Web-based System Manager Remote Client allow you the flexibility to access your managed systems (including HMCs) from multiple locations using multiple HMCs. For more detailed information about the use of the HMC, refer to the IBM Systems Hardware Information Center. Open Firmware A System p5 server has one instance of Open Firmware both when in the partitioned environment and when running as a full system partition.

    This chapter provides more detailed information about IBM System p5 design features that help lower the total cost of ownership (TCO). IBM reliability, availability, and service (RAS) technology allows you to improve your TCO architecture by reducing unplanned down time.
  • Page 92: Reliability, Availability, And Serviceability

    3.1 Reliability, availability, and serviceability Excellent quality and reliability are inherent in all aspects of the IBM System p processor design and manufacturing. The fundamental objective of the design approach is to minimize outages. The RAS features help to ensure that the system operates when required, performs reliably, and efficiently handles any failures that might occur.

    3.1.5 N+1 redundancy The use of redundant parts allows the p5-550 and p5-550Q 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-mount p5-550 or p5-550Q requires two power cords, which are not included in the base order.
  • Page 96: Serviceability

    The p5-550 and p5-550Q are designed for client setup of the machine and for the subsequent addition of most hardware features. The p5-550 and p5-550Q also allow clients to replace service parts (Client Replaceable Unit). To accomplish this, the p5-550 or p5-550Q provide IBM System p5 550 and 550Q Technical Overview and Introduction...

    – This concurrent maintenance task requires HMC guided support. 3.2 Manageability This section describes the functions and tools that are provided for IBM System p5 servers to ease management. 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 will not boot. It can be performed either from an ASMI, HMC, or 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 computer and monitors it for hardware errors. It reports detected errors, assuming they meet certain criteria for severity, to IBM for service with no client intervention. It is an enhanced version of Service Director™ with a graphical user interface.
  • Page 100 Service Agent can be configured to connect to IBM either using a modem or a network connection. In any case, the communication is encrypted and strong authentication is used. Service Agent sends outbound transmissions only and does not allow any inbound connection attempts.
  • Page 101: Ibm System P5 Firmware Maintenance

    You can configure the HMC to use the Service Agent call-home feature to send IBM event information. Service Focal Point is also available 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 via Service Agent is possible.
  • Page 102: Cluster Solution

    For hardware control, an HMC is required. One HMC can also control several IBM System p5 servers that are part of the cluster. If a p5-550 or p5-550Q that is configured in partition mode (with physical or virtual resources) is part of the cluster, all partitions must be part of the cluster.
  • Page 103 CSM client side is automatically installed and ready when you install AIX, so each system or logical partition is cluster-ready. The CSM V1.4 on AIX 5L and Linux introduces an optional IBM CSM High Availability Management Server (HA MS) feature, which is designed to allow automated failover of the CSM management server to a backup management server.
