NEW-GENERATION SERVER TECHNOLOGYFigure 6. ITA GUI showing SNMP trap highlightedcheck the Enable Destination box and enter the IP address of thedestination system to which the PET alerts should be sent.Finally, the network interface card (NIC) of the BMC shouldbe enabled and correctly configured so that PET alerts canbe sent. Administrators should select System>Main SystemChassis>BMC on the left navigation bar of the OMSA GUI, andselect Configuration>LAN. Administrators should make sure thatthe Enable IPMI Over LAN box in the NIC Configuration sectionof the GUI is selected, and that the NIC has the correct IP addressassigned to it—either by using Dynamic Host Configuration Protocol(DHCP) or a static IP address.PET configuration can also be viewed and managed using CLIcommands. Detailed instructions can be found in the OMSA onlinedocumentation.SNMP traps versus PET alertsThe destination system for SNMP traps and PET alerts must havean SNMP manager program installed, such as <strong>Dell</strong> OpenManageIT Assistant (ITA), which receives, recognizes, filters, and actsupon SNMP traps and PET alerts. PET alerts are, in fact, SNMPtraps with specified trap fields defined in the IPMI Platform EventTrap format.If both SNMP traps and PET alerts are configured for the sametype of component and event (for example, when a temperaturesensor detects a warning state), an SNMP trap is generated and sentby OMSA when the event occurs, while a PET alert is generatedand sent by the affected system’s BMC. If destinations for bothof the alerts are set to the same management station, which hasITA installed, both the SNMP trap and the PET alert will reach themanagement station and be recognized, as shown in Figure 6. TheSNMP trap (the first line item in Figure 6) and the PET alert (thesecond line item in Figure 6) have different values for the host name.The SNMP trap uses the OS host name as its host name becausethe trap is generated and sent by OMSA and the OS, while the PETalert uses the BMC host name because the PET is generated andsent by the BMC. These two alertsalso display different values inthe description.Maximized uptime andperformance through alertingAlerting mechanisms providedby OMSA allow administrators tobe notified of system events, orstatus changes of system componentsor of the system itself. Differentalerting mechanisms—atthe local, remote, or hardwareSNMP traps can beenabled or disabled bysystem, by category ofcomponent, by individualcomponent, and byseverity level.and firmware levels—provide administrators with options andflexibility regarding how they can be warned of system abnormalities.The sooner and more accurately administrators are notifiedof potential and actual system failures, the more time they haveto discover the root cause of a given problem and take appropriateaction to help maintain continuous system uptime.Haihong Zhuo is a software engineer consultant working in the System ManagementInstrumentation team in the <strong>Dell</strong> Enterprise Software Development Group.

SYSTEMS MANAGEMENTDeploying <strong>Dell</strong> Update Packages Using MicrosoftSystems Management Server 2003Administrators can gain a powerful set of systems management tools by integrating<strong>Dell</strong> Update Packages with Microsoft Systems Management Server (SMS) 2003. Thisarticle provides an overview of how administrators can use Microsoft SMS 2003 tobuild a software distribution solution that helps manage <strong>Dell</strong> <strong>Power</strong>Edge servers in aheterogeneous environment.BY SANDEEP KARANDIKAR AND MANOJ GUJARATHIEnterprise IT departments typically manage a heterogeneousmix of decentralized hardware and software applications.Successful administration of complex environmentscan be challenging, and IT professionals rely on robust systemsmanagement offerings to help achieve their goals.One of the thorniest enterprise management issuesis patch management, which includes keeping applicationsoftware, operating systems, and system softwareup-to-date. The basic tasks of patch management includeinventorying an organization’s hardware for existing softwareversion levels; comparing the inventory results to alist of current or desired software versions; and allowingusers to apply one or more updates.To address enterprise needs for enhanced patch management,<strong>Dell</strong> is expanding <strong>Dell</strong> OpenManage systemsoftware update technologies and products. This articlediscusses how <strong>Dell</strong> Update Packages can be integratedwith Microsoft Systems Management Server (SMS) 2003to manage <strong>Dell</strong> <strong>Power</strong>Edge servers in a heterogeneousenterprise environment.<strong>Dell</strong> Update Packages are server BIOS, firmware, anddriver system software updates delivered in a consistent,self-extracting zip file format. They are available on the<strong>Dell</strong> support site (support.dell.com) and offer ease andflexibility for updating system software on <strong>Dell</strong> <strong>Power</strong>Edgeservers in an operating system (OS)–present environment.The current suites of packages allow administrators toupdate the following system software components: 1• System BIOS• System firmware, also known as the EmbeddedServer Management (ESM) firmware• Remote access controller (RAC) firmware• <strong>Power</strong>Edge Expandable RAID Controller (PERC)firmware and device drivers• Network interface card (NIC) drivers1For the current list of supported devices, visit the <strong>Dell</strong> support site at support.dell.com.www.dell.com/powersolutions Reprinted from <strong>Dell</strong> <strong>Power</strong> <strong>Solutions</strong>, February 2005.
