HP-UX 11i Version 2 December 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/ The HP Integrity Virtual Machines (HPVM) 3.5 release supports two new Accelerated Virtual I/O device drivers that significantly improve HPVM I/O performance. The HPVM 3.5 product is shipped via HP Independent Media and is not included with the December 2007 Operating Environment Update Release (OEUR) of HP-UX 11i v2. The Accelerated Virtual I/O (AVIO) solution is composed of four new products: GuestAvioLan, HostAvioLan, GuestAvioStor, and HostAvioStor. The initial version for these products is B.11.23.0712 for all and, as stated above, all are supported with the HPVM release 3.5. The configuration process for the new AVIO devices is basically the same as the existing VIO devices. The only difference is the device names used in the hpvmcreate/hpvmmodify commands. The names of the AVIO devices are aviolan (or avio_lan) and aviostor (or avio_stor). The new AVIO storage and lan devices deliver a new re-architected I/O path for HPVM. These products are shipping for the first time on the HP-UX 11i v2 December 2007 Operating Environments. All four AVIO products are Default-Installed on the December 2007 Foundation Operating Environment. The new AVIO storage and lan products provide significant performance improvements over the existing VIO products. These new HPVM AVIO devices provide significant performance improvement (up to 60% decrease in Service Demand and up to 2X increase in throughput) over the existing (fully emulated) Virtual I/O (VIO) devices. The new AVIO products can coexist with the existing VIO products. In order to select the new AVIO products as your guest driver, use aviolan (or avio_lan) and aviostor (or avio_stor). This new HPVM AVIO devices provide significant performance improvement (up to 60% decrease in Service Demand and up to 2X increase in throughput) over the existing (fully emulated) Virtual I/O (VIO) devices. For further information, see the AVIO-specific additions to the following HPVM documents, all available at http://docs.hp.com/en/vse.html#HP%20Integrity%20Virtual%20Machines:
In addition, see the AVIO-specific additions to the manpages of the following commands:
HP Application Discovery (amgr) 3.1.00 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. It also provides a template editor so that you can define applications for discovery and for addition to monitored and managed workloads in VSE Virtualization Manager. Version 3.1.00 of Application Discovery is integrated into the Virtual Server Environment, which is available from HP Software Depot: http://software.hp.com/. The Application Discovery agent (AppDiscAgent) is available with the software and here on the Operating Environment (OE) media. AppDiscAgent 3.1.00.01. Defect fixes have been incorporated into this release. See the VSE Management Software Release Notes Version A.03.00.01 available at http://docs.hp.com/en/vse.html for more information. The Application Discovery agent is default-installed on the OE media, and is also available from the AR media. 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 server is not 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.3.00.01 for details (with the software or 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.
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:
gWLM A.03.00.01.x includes the following changes:
gWLM A.03.00.01.x provides more flexibility in managing your systems. Linux managed nodes are no longer supported. For further information, see the following:
The HP Integrity Virtual Machines Provider (VM Provider), version A.03.50, 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 (HP 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 only used through a WBEM interface. It is not invoked directly by the user. HP Integrity Virtual Machines Provider has been upgraded from A.03.00 to A.03.50 to provide support for new features in HP Integrity Virtual Machines. 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. Complete information is in the following documents, which are both available on http://docs.hp.com under the HP Virtual Server Environment (VSE) collection:
HP Integrity Virtual Machines (VMGuestLib) is a subset of the HP Integrity Virtual Machines API Library used by WBEM Provider. HP Integrity Virtual Machines (VMGuestLib) upgrade from version A.03.00 includes support for the new features of HP Integrity Virtual Machines A.03.50. 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. Complete information is in the following documents, which are both available on http://docs.hp.com under the HP Virtual Server Environment (VSE) collection:
HP-UX Virtual Partitions (vPars) A.04.05 enables multiple instances of the HP-UX 11i version 2 Operating Environment (OE) to run simultaneously on one server or within one nPartition, with each OE instance hosting its own set of applications in an isolated environment. When vPars A.04.05 is available, it can be purchased at the HP-UX Virtual Partitions (T1335BC) website at Software Depot: http://software.hp.com/portal/swdepot/displayProductInfo.do?productNumber=T1335BC vPars A.04.05 provides support for mixed HP-UX 11i v1/v2 vPars environments, which enable virtual partitions running HP-UX 11i v1 (B.11.11) and HP-UX 11i v2 (B.11.23) to exist in the same nPartition. Only the vPars A.04.05 and vPars A.03.05 releases are supported in a mixed HP-UX 11i v1/v2 vPars environment.
For further information, see the following websites: HP-UX Workload Manager (WLM) A.03.02 provides goal-based workload management. This management enables automatic resource allocation and application performance management through the use of prioritized service-level objectives (SLOs). It provides this functionality by automating features of HP-UX Virtual Partitions, nPartitions, Processor Sets, and HP Process Resource Manager (PRM). In December 2007, WLM has not changed on the Operating Environments (OE) media. However, WLM is available for separate purchase on the Application Release (AR) media.
Regarding WLM on the AR media: As of version A.03.01, WLM no longer includes PRM in the bundle. However, with your purchase of WLM, you are entitled to a PRM license. For information on receiving the PRM license, contact your regional licensing service organization. Performance is improved when WLM is used properly, but can degrade when WLM is not configured appropriately. For additional information about WLM, see the following:
The nPartition Provider version B.01.07 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 product is only used through a WBEM interface. It is not invoked directly by the user. nPartition Provider has been updated to version B.01.07 to incorporate defect fixes. You should be aware of the following items that may affect performance:
Complete information is in the nPartition provider product data sheet, installed as /opt/nparprovider/doc/nParProviderDataSheet.html The Utilization Provider version A.01.06.03.01 is a lightweight daemon (utild) that records system-utilization data on a 5-minute interval. System-utilization data includes: CPU, memory, disk, & network. This product also includes a WBEM provider for access to the utilization data. The Utilization Provider for HP-UX 11i v2 (11.23) has been updated to a new version number to correct errors in the previous release (version A.01.06.02.xx), which does not operate correctly under HP-UX 11i v2. This update does not apply to HP-UX 11i v1 (11.11) or HP-UX 11i v3 (11.31). For those versions of HP-UX, Utilization Provider version A.01.06.02.xx should continue to be used. 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 website 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. Patch PHKL_33752 is required on Dual Core Intel® Itanium® processor systems being monitored with Capacity Advisor. 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 website at |
