HP-UX 11i Version 3 September 2007 Release Notes: Operating Environments Update Release > Chapter 5 General System Administration
HP Partitioning and Virtual Server Environment |
|
|
HP offers a full line of hardware and software partitioning capabilities, including nPartitions, virtual partitions, and HP Integrity Virtual Machines. The HP Virtual Server Environment (VSE) builds on HP partitioning products and the VSE Management Software to help you maximize the use of your server resources in response to changing business needs. The HP-UX Operating Environments include WBEM providers and agent software that enable your systems to operate in the VSE. The VSE Management Software is not included in the Operating Environments, but is available for download from the following Web site: http://docs.hp.com/en/vsemgmt/. Cell online activation applies only to a cellular complex (see "Hardware Affected" section below for the list of machines that can be considered a cellular complex). The cell online activation operation is used to activate an inactive cell while the nPartition containing it continues to run. For this operation to be possible, an nPartition must be running HP-UX 11i v3 with the September 2007 Operating Environment Update Release and that nPartition must contain a cell in the inactive state. Upon completion of the cell online activation operation, the processor and memory resources on the activated cell are available for use by the operating system and applications, and any I/O resources will be ready to be activated. When the new cell is activated, any memory on the cell is configured as Cell Local Memory (CLM), regardless of the clm_value attribute established by the parmodify command. The activated cell may optionally have an I/O expander attached to it. If so, the host bus adapter is configured into the nPartition, but the individual I/O adapters are not configured unless the system administrator issues a separate subsequent olrad command to do so. A new command parolrad is enabled. The -a option to the command permits a cell to be online activated. You have been able to partition a cellular complex into nPartitions and add a new cell to an existing nPartition. However, prior to HP-UX 11i v3 (11.31), the new cell would not be integrated into the nPartition until such time as it was rebooted. With cell online activation, the new cell is integrated into the nPartition immediately upon command while it continues to run the operating system. There are no compatibility issues for source files, scripts, makefiles, executables and data. There are no tunable changes. Tunable values that are proportional to the amount of memory in an nPartition are adjusted automatically as part of the cell online addition operation. There are no differences in behavior or functionality between PA and IPF. There are no regressions from previous releases of HP-UX. Dynamic nPartitions is supported on the following servers: rp7420, rp7440, rp8420, rp8440, rx7620, rx7640, rx8620, rx8640, HP 9000 Superdome servers, including the SD16A, SD32A, and SD64A models (but not the SD16000, SD32000, and SD64000 models), and HP Integrity Superdome (SD16A, SD32A, and SD64A, SD16B, SD32B, and SD64B) This is the set of machines that appear as a cellular complex. Each of these machines requires a minimum firmware revision to support Dynamic nPartitions, as described in the table System Firmware Matrixes: HP-UX 11i v3, HP-UX11i v2, and PCI I/O Adapters located at http://docs.hp.com/en/SFWM1/index.html . For nearly every customer workload, performance will improve after performing a cell online activation event. The increase in performance may not be as great as it would be if the system were rebooted. The gap between realized performance and potential performance after a reboot should be less than 5%. However, the potential performance gap may increase as more cells are activated online, and could be significant if the number of added cells exceeds the number of cells in the nPartition at the time it booted. For detailed information, see the following: Manpages:
Documents (available at http://docs.hp.com/en/hw.html#System%20Administration):
Cell online deactivation applies only to a cellular complex (see “Hardware Affected” section below for the list of machines that can be considered a cellular complex). The cell online deactivation operation is used to deactivate an active cell while the nPartition containing it continues to run. For this operation to be possible, an nPartition must be running HP-UX 11i v3 with the September 2007 OEUR, that nPartition must contain a cell that is eligible for deactivation, and any I/O resources on that cell must be inactive. Upon completion of the cell online deactivation operation, the processor and memory resources on the deactivated cell will no longer be used by the operating system or applications. All of these conditions must be satisfied for the cell online deactivation operation to succeed:
A new command parolrad is enabled. The -d option to the command permits a cell to be online deactivated. You have been able to partition a cellular complex into nPartitions and delete a cell from the nPartition. However, prior to HP-UX 11i v3 (11.31), the cell would not be deleted from the nPartition until such time as it was rebooted. With cell online deactivation, the new cell is deleted from the nPartition immediately upon command while it continues to run the operating system. There are no compatibility issues for source files, scripts, makefiles, executables and data. There are no tunable changes. Tunable values that are proportional to the amount of memory in an nPartition are adjusted automatically as part of the cell online deletion operation. There are no differences in behavior or functionality between PA and IPF. There are no regressions from previous releases of HP-UX. Dynamic nPartitions is supported on the following servers: rp7420, rp7440, rp8420, rp8440, rx7620, rx7640, rx8620, rx8640, HP 9000 Superdome servers, including the SD16A, SD32A, and SD64A models (but not the SD16000, SD32000, and SD64000 models), and HP Integrity Superdome (SD16A, SD32A, and SD64A, SD16B, SD32B, and SD64B). This is the set of machines that appear as a cellular complex. Each of these machines requires a minimum firmware revision to support Dynamic nPartitions, as described in the table System Firmware Matrixes: HP-UX 11i v3, HP-UX11i v2, and PCI I/O Adapters located at http://docs.hp.com/en/SFWM1/index.html . Since the online cell deletion operation reduces the resources in an nPartition, its performance capacity will be diminished in proportion to the amount of resources deleted. Therefore, it is not recommended to perform a cell deletion operation unless the nPartition has sufficient idle or underutilized resources. For detailed information, see the following: Manpages:
Documents (available at http://docs.hp.com/en/hw.html#System%20Administration):
The HP-UX nPartition Configuration Commands is a set of system administration commands to create/modify/remove partitions, control power to cells and I/O chassis, flash/turn off attention LEDs for cells, cabinets and I/O chassis, and display information about a hardware partitionable complex. The command line interface for nPartition configuration consists of the following commands:
The nPartition configuration commands are not performance sensitive. Overall response time depends on WBEM stack elements and network bandwidth. For detailed information, see the following: Manpages:
Documents (available at http://docs.hp.com/en/hw.html#System%20Administration):
The nPartition Provider version B.31.01.07.02 is the HP-UX WBEM Services provider for nPartition-related information on partitionable systems. This product is used by Partition Manager and the partition commands to configure and manage HP systems that support nPartitions. With this component, partitionable systems can be managed both locally and remotely. The nPartition Provider is only used through a WBEM interface. It is not invoked directly by a user.
Complete information is in the nPartition provider product data sheet, installed as: /opt/nparprovider/doc/nParProviderDataSheet.html Partition Manager v2.0, version B.31.02.04.00 provides system administrators with a convenient graphical user interface for configuration and management of nPartitions on HP server systems. In addition, Partition Manager enhances the reliability and performance of HP partitioning products by providing automatic detection of several types of configuration problems. This release of Partition Manager includes support for Dynamic nPartitions (cell online activation and cell online deactivation). Online cell operations are supported only on servers based on the HP sx1000 or sx2000 chipset. The cell being activated or deactivated must be assigned to an nPartition running HP-UX 11i v3 (B.11.31) September 2007 or later. The primary documentation for this product consists of a set of HTML online help files. The online help is accessed through context-sensitive help links in Partition Manager. The parmgr command is documented in the parmgr(1M) manpage that is included with the product. Both English and Japanese versions of the manpage are included. Additional information about Partition Manager, including links to download all currently available versions, can be found at http://docs.hp.com/en/PARMGR2/ . vPars A.05.02 enables multiple instances of the HP-UX 11i v3 Operating Environment (OE) to run simultaneously on one server or within one nPartition, with each OE instance hosting its own set of applications in a isolated environment. vPars A.05.02 also supports a mixed HP-UX 11i v2/v3 vPars environment. A mixed HP-UX 11i v2/v3 vPars environment allows you to have a vPars A.05.0x Monitor and database that simultaneously supports virtual partitions running vPars A.05.0x on HP-UX 11i v3 (11.31) and virtual partitions running vPars A.04.02 or later on HP-UX 11i v2 (11.23). Virtual partitions running vPars A.03.xx on HP-UX 11i v1 (11.11) are not supported in a mixed HP-UX 11i v2/v3 vPars environment. When vPars A.05.02 is available, it can be purchased at the HP-UX Virtual Partitions (T1335CC) Web site at the Software Depot: http://software.hp.com/portal/swdepot/displayProductInfo.do?productNumber=T1335CC. vPars A.05.02 provides support for the following:
For detailed information, see the following: Software Depot Web Site: http://software.hp.com/portal/swdepot/displayProductInfo.do?productNumber=T1335CC Documents: Application Discovery (amgr) HP Application Discovery, version 3.1.00.01, provides system administrators and operators with a convenient graphical user interface for browsing an inventory of applications and processes running within a computing network. Screens show the data by host and by application, and you can monitor resource usage at the level of individual processes within an application. In addition, Application Discovery provides automatic detection of several types of application events, and it provides a template editor so that you can expand the scope of discovery to include third-party and custom applications. Application Discovery is integrated with VSE Virtualization Manager, gWLM, and Capacity Advisor to allow VSE workloads to be defined based on discovered applications. Version 3.1.00.01 of Application Discovery contains defect fixes to improve performance, reliability, and quality of the collected data. The Application Discovery agent (AppDiscAgent) is available with Virtual Server Environment software from HP Software Depot (http://software.hp.com/) and here on the OE media. AppDiscAgent The Application Discovery agent is default-installed on the OE media, and is also available from the AR media. Note that the Application Discovery agent is not automatically started without explicit user action from HP System Insight Manager. Install AppDiscAgent on each managed system where you have applications and installed software that you want to inventory and monitor. The agent securely supplies data to Application Discovery server at intervals that can be set by a system administrator. Using AppDiscAgent 3.1.00.01 with previous versions of Application Discovery 3.x server is fully supported. Using the Application Discovery server 3.1.00.01 (not in the OE) with previous versions of the Application Discovery 3.x agents is also supported. AppDiscAgent 3.1.00.01 requires the presence of Web-Based Enterprise Management (WBEM) services, Secure Shell (SSH), and OpenSSL for correct operation and secure data transmission. Consult the VSE Management Software Installation and Update Guide, Version A.03.00.00 for details (included with the software or available online at http://docs.hp.com/en/vse.html). Application Discovery requires a “warmup period,” during which the agent collects the initial set of data for a managed node. The degree to which “warmup” affects memory usage by Application Discovery server on the central management system depends on the number of managed nodes that are inventoried at the same time. For detailed information, see the following documentation:
Only English versions of the man pages and other documentation are included at this time. HP Global Workload Manager (gWLM), a component of the HP Virtual Server Environment (VSE) Suite, allows you to centrally define resource-sharing policies that you can use across multiple HP servers. These policies increase system utilization and facilitate controlled sharing of system resources. In addition, gWLM provides both real-time and historical monitoring of the resource allocation. gWLM has three components:
This release of gWLM includes the following changes:
For detailed information, see the following:
HP PRM C.03.03.01 provides an efficient and flexible way to manage resource allocation at times of peak system load. It gives the system administrator the ability to group users or processes together and guarantee each group minimum amounts of the total CPU, real memory, and disk bandwidth available. HP PRM has been updated to version C.03.03.01 with the following changes:
PRM is designed to set resource allocations (CPU, memory, disk bandwidth) for applications. Mis-configuration can result in performance degradation. For detailed information, see the following:
This fileset allows PRM and other related products to control system resources from inside the kernel. The PRM Libraries (B7697BA) is now known as PRMKernelSW. PRMKernelSW (version C.03.03.01) contains only the PRM kernel fileset, PRM-Sw-Krn. For detailed information see the following documents:
These documents are available at http://docs.hp.com/hpux/ha/index.html#Process%20Resource%20Manager . This bundle includes the PRM API required by PRM (Process Resource Manager). The PRMLibraries (B7697BA) product that contained only the PRM kernel fileset (PRM-Sw-Krn) is now known as PRMKernelSW. The PRMLibraries product (version C.03.03.01) now contains the PRM API. For detailed information, see the following PRM documents:
These documents are available at http://docs.hp.com/hpux/ha/index.html#Process%20Resource%20Manager . The HP Integrity Virtual Machines Provider (VM Provider) is the HP-UX WBEM Services provider for Virtual Machines-related information on VM Host and Guests. This product is used by HP Systems Insight Manager (SIM) to display information about HP systems that support HP Integrity Virtual Machines. It is also used by HP Integrity Virtual Machines Manager to visualize, configure, and manage HP systems that support HP Integrity Virtual Machines. The VM Provider is used only through a WBEM interface. It is not invoked directly by the user. VM Provider is upgraded to version A.03.00 to support the new features of HP Integrity Virtual Machines A.03.00. This product allows HP Systems Insight Manager (SIM) to display information about HP systems that support HP Integrity Virtual Machines. If VMProvider, VMGuestLib, and HP Integrity Virtual Machines are already currently installed, upgrades of any of these three products require upgrades of the other two such that all versions are compatible and all products function correctly. For more information, see the following (available at http://docs.hp.com):
VMGuestLib is a subset of the HP Integrity Virtual Machines API Library used by WBEM Provider. VMGuestLib is upgraded from version A.02.00 includes support for the new features of HP Integrity Virtual Machines A.03.00. This product allows HP Systems Insight Manager (SIM) to display information about HP systems that support HP Integrity Virtual Machines. If VMProvider, VMGuestLib, and HP Integrity Virtual Machines are already currently installed, upgrades of any of these three products require upgrades of the others such that all versions are compatible and all products function correctly. For more information, see the following (available at http://docs.hp.com):
The Utilization Provider version A.01.06.02.xx is a lightweight daemon (utild) that records system-utilization data on a 5-minute interval. System-utilization data includes CPU, memory, disk, and network. This product also includes a WBEM provider for access to the utilization data. The Utilization Provider has been updated to a new version number to include defect fixes. This version addresses a problem with incorrectly reporting the clock speed of Dual Core Intel® Itanium® processors. Detailed information about this problem and its resolution is available on the VSE Management Software Web site at http://docs.hp.com/en/vsemgmt/ The latest updates to the VSE Management Software agents and providers, including the Utilization Provider, can be downloaded from the HP VSE Managed Node Software Update Web site at When Utilization Provider is installed, it launches the utild daemon, which consumes minimal CPU, memory, and disk resources. Up to 30 days of utilization data are kept in data files in /var/adm/util. The total disk space used by these files should not exceed 20MB in the default utild installation. The Virtual Server Environment (VSE) Management Software, running on an HP Systems Insight Manager Central Management Server, requires the Utilization Provider to be running on all managed systems. If the Utilization Provider is removed, the system cannot be managed by the VSE Management Software. This version of the Utilization Provider depends on HP WBEM Services for HP-UX version A.02.00.11 or later. The utild process wakes up every 5 minutes and discovers and records the four metrics (CPU, memory, disk, and network). This discovery has minimal impact on system performance. The utild daemon is described in the utild(1M) manpage. WBEM schema (MOF files) are installed in /opt/util/mof For more information about the VSE Management Software and Utilization Provider, see the VSE Management Software Web site at |
