Terminology
Adapter A part that electrically or physically connects a device to a computer or to another device. ASM Advanced System Management. CEC Central Electronics Complex. This is the collection of processors that run the server. CLI Command Line Interface. A type of computer interface in which the input command is a string of text characters. Contrast with Graphical User Interface (GUI). CoD Capacity on Demand. Concurrent Maintenance This is the process of removing and replacing system components while the system remains under power. Note that this capability cannot be assumed for all system components. Configuration The manner in which the hardware and software of an information processing system are organized and interconnected. CRU Customer Replaceable Unit. EED Extended Error Data. ESS Enterprise Storage Server. Ethernet A 10-Mbps baseband local area network that allows multiple stations to access the transmission medium at will without prior coordination, avoids contention by using carrier sense and deference, and resolves contention by using collision detection and delayed retransmission. Ethernet uses carrier sense multiple access with collision detection (CSMA/CD). Firewall A functional unit that protects and controls the connection of one network to other networks. The firewall (a) prevents unwanted or unauthorized communication traffic from entering the protected network and (b) allows only selected communication traffic to leave the protected network. Fix Pack A combination of many single fixes (PTFs) for product components that are dependent on or related to each other. It can include new features, functions, or enhancements. FRU Field Replaceable Unit. FSP Flexible Service Processor. GUI Graphical User Interface. A type of computer interface consisting of a visual metaphor of a real-world scene, often of a desktop. Within that scene are icons, representing actual objects, that the user can access and manipulate with a pointing device. Contrast with Command Line Interface. HMC Hardware Management Console. The HMC for POWER6 is a system that controls managed systems, such as one or more POWER6 servers. IASP Independent Auxiliary Storage Pool. IDE Integrated Drive Electronics. A standard interface for IBM compatible hard drives. Information Center The source for all of your technical information needs for eServer systems. IPL Initial Program Load. Equivalent to a power-on reset. LIC Licensed Internal Code, also called server firmware, is software that enables your hardware.		Load Identifier (LID) Load Identifiers represent the smallest unit or binary image that can be loaded into PHYP, Partition FirmWare, or FSP. LIDs are analogous to files. Logical Partition (LPAR) Logical partitioning is the division of a computer's processors, memory, and storage into multiple sets of resources so that each set of resources can be operated independently with its own operating system instance and applications. Thus, it follows that a logical partition is one such set of system resources. Each partition must have a unique name and at least one partition profile. A partition can have several partition profiles, but it reads only one partition profile when it is activated. You select a partition profile when you activate the partition; otherwise, the default partition profile is used. You can designate any partition profile as the default partition profile. Partition Profile A partition profile is the definition of a partition's system resources, which include the relevant CPU, memory, and I/O slots. Partition profiles are stored in and retrieved from system memory upon requests sent from the HMC. After the profiles are set up, the system automatically returns to this configured state when powered on. Note that you do not have to associate all the partition profiles with system profiles. And, it is possible to associate a partition profile with multiple system profiles. PHYP POWER Hypervisor. This is the converged platform firmware for eServer systems. PTF Program Temporary Fix. This is a temporary solution to or bypass of a problem diagnosed by IBM as resulting from a defect in a current unaltered release of a licensed program. RAID Redundant Arrays of Independent Disks. Resource Link A customized Web-based solution providing customers and service representatives all that is needed to plan for, install, and maintain their IBM eServer hardware and software products. Service Focal Point Service Focal Point is an application on the Hardware Management Console that enables you to diagnose and repair problems on the system. You can also use Service Focal Point to call service functions on systems and logical partitions that are not associated with a particular problem. Serviceable Event System error that requires service. Serviceable events are typically reported to Service Focal Point on the HMC. SMP Symmetric Multiprocessor. SRC System Reference Number. SRN Service Request Number. System Profile A system profile provides a collection of partition profiles that are started at the same time. Partition profiles are activated in the order of the list defined in the system profile. TCP/IP Transmission Control Protocol/Internet Protocol. TCP/IP provides reliable end-to-end connections between applications over interconnected networks of different types. Telnet In the Internet suite of protocols, a protocol that provides remote terminal connection service. It allows users of one host to log on to a remote host and interact as directly attached terminal users of that host. VPD Vital Product Data. WCII Worldwide Customized Install Instructions.
