This pack supports HP ProLiant ML and DL 300, 500, and 700 servers, HP ProLiant server blades, and the HP BladeSystem c-Class. • SmartStart — single-server deployment tool that simplifies server setup and provides consistent server configurations. • ProLiant Support Pack (PSP) — collection of optimized ProLiant server drivers, utilities, and management agents. • HP Systems Insight Manager (SIM) — provides comprehensive fault, asset, and configuration management for all of your HP server platforms running Microsoft® Windows®, Linux, HP-UX, and other supported operating systems. • System Management Homepage — provides a consolidated view of all system health and configuration information and simplifies access to HP Insight Management WBEM Providers and HP Insight Management Agents running on your ProLiant server. For additional information on the HP Insight Management WBEM Providers go to www.hp.com/go/HPwbem Extend your server infrastructure and management capabilities with extra tools and value packs. More information is available at www.hp.com/servers/proliantessentials SmartStart Installation Guidelines SmartStart performs server setup by assisting hardware configuration and installation of leading operating systems on RBSU (ROM-Based Setup Utility) systems on HP ProLiant servers. SmartStart automatically installs the PSP after the assisted installation. IMPORTANT: The SmartStart CD is bootable only on servers with RBSU. Review the support matrix on www.hp.com/servers/smartstart for a complete list of supported servers and operating systems. • Be sure that the system meets the operating system requirements and the server is supported by SmartStart. • Be sure that the operating system CD and product identification numbers and keys are available, if applicable. • Connect the server hardware as shown on the hardware installation and configuration poster. 1. Boot the SmartStart CD and click Getting Started, for more details on server configuration and OS installation. IMPORTANT: Server hardware and array controller configuration is required before you begin software installation using either Assisted or Manual Installation. 2. Configure the server using RBSU (ROM-Based Setup Utility) by pressin the F9 key when the system first boots. Configure the array controller hardware using ORCA (Option ROM Configuration for Arrays) or the Adaptec RAID Configuration Utility as prompted. ORCA and the Adaptec RAID Configuration Utility are available by pressing the F8 key or Ctrl+A when the system first boots. RBSU and ACU (Array Configuration Utility) can also be launched by booting SmartStart. Operating System Installation Assisted Installation: Boot the SmartStart CD to validate the hardware configuration, run system utilities, and launch server setup. Server setup walks you through interview questions to prepare the server for operating system installation. Follow the on-screen instructions to complete the rest o the OS installation. The PSP is automatically installed after the OS installation. Manual Installation using the OS CD: After configuring the hardware, boo the operating system CD to initiate and complete the operating system installation. After installing the OS, insert the SmartStart CD and install th operating system-specific PSP onto the server.

System Memory Troubleshooting Best Practices for HP ProLiant Servers Accurately troubleshooting system memory issues in ProLiant server configurations is an important process that can help prevent unnecessary replacement of hardware components. In addition, accurate problem diagnosis prevents customers from experiencing unnecessary downtime while waiting for hardware that may not need to be replaced. Following standard troubleshooting guidelines and using them each time a memory issue is suspected helps to establish this. HP has developed several methods for troubleshooting memory problems in ProLiant servers. The purpose of this white paper is to assist HP customers in troubleshooting system memory problems by successfully isolating the specific DIMMs causing the problem. This helps to prevent nonessential replacement of unaffected DIMMs or, in some cases, entire banks of memory. In addition, effective troubleshooting can help determine if a firmware or other software download can resolve a problem without replacing hardware. This white paper covers the following topics: • Why should I troubleshoot every system memory problem? • How can I tell if a memory problem has occurred? • What tools are available from HP to help identify a failing DIMM? • Troubleshooting using HP Insight Diagnostics Online Edition • Troubleshooting using HP Insight Diagnostics Offline Edition • Troubleshooting flowchart for bootable systems • Troubleshooting flowchart for non-bootable systems • What role does firmware play in solving system memory problems? • Why Buy HP Memory? • Other troubleshooting resources
