1 hp NonStop servers integrated manageability a technical brief from hp integrating NonStop servers with hp OpenView using SNMP HP NonStop servers integrate with many of the HP OpenView products. OpenView Network Node Manager software is the industry s most comprehensive, intelligent, and easy-to-use network management solution. Network Node Manager software automatically discovers your network and provides customizable maps and submaps so you can see visually what is happening. Network Node Manager software also enables event management and allows remote access via the Web. This technical brief outlines the functionality provided when integrating NonStop servers with OpenView and specific Network Node Manager integration instructions. leveraging industry-standard SNMP functionality The Simple Network Management Protocol (SNMP) makes it possible to manage NonStop servers using OpenView software. SNMP is the industry-leading standardsbased method for managing all devices in a network, including hubs, routers, workstations, and servers. SNMP provides an industry-standard protocol as well as management information for managing networks and servers. NonStop servers provide robust manageability offerings that feature the following SNMP functionality: NonStop Extensible SNMP Agent and TCP/IP subagent software take advantage of the system advantages of NonStop servers such as continuous availability, online configuration, and scalability. The Host Resources MIB provides server management attributes such as processor utilization, devices attached, and processes running. The TCP/IP MIB II provides management information for TCP/IP-based networks. SNMP Manager Services provides a set of libraries for developing SNMP manager functions and applications on a NonStop server. The Distributed System Management (DSM) architecture provides additional functionality, allowing NonStop servers to be managed by Network Node Manager software. This powerful architecture enables a single system or network of systems to be viewed as a single entity. DSM also provides a messaging environment called Event Management Service (EMS). EMS messages reflecting the fault and performance status of system components, subsystems, and applications are forwarded to the EMS event log. The EMS to SNMP trap converter allows NonStop server EMS event messages to be forwarded as SNMP traps and displayed by OpenView software. 1

2 OpenView network node manager functions Network Node Manager software supports a variety of management functions for NonStop servers, including Auto-discovery of NonStop servers (see figure 1) Event viewing (see figure 2) TCP/IP packet activity (see figure 3) Integrated command and control and operator instructions are available using HP Web ViewPoint software. Figure 1. Auto-discovery of NonStop server. Figure 2. Event viewing. 2

TCP/IP activity. network node manager integration process overview Network Node Manager software includes support for NonStop servers using the following components: SNMP agent TCP/IP subagent Event Management System (EMS) Web ViewPoint software The SNMP agents and EMS subsystem are included with the operating system. An evaluation copy of Web ViewPoint Version 4 software can be downloaded from the following location: Web ViewPoint Version 4 software contains an event viewer, an object manager, and a performance monitor for NonStop systems. The following table summarizes the NonStop server functionality that is supported by OpenView Network Node Manager software. NonStop server functionality supported by OpenView network node manager software if you start the following on a NonStop server... SNMP agent TCP/IP subagent EMS to SNMP distributor and configure SNMP Trap Destination and Community strings Web ViewPoint software on port 280 Web Server software on port you will be able to see the following with OpenView network node manager software Icons for NonStop server systems TCP/IP performance information emsmessage as an event type Tools->Web browser->management page Tools->Web browser->server home page 3

Register the emsmib Set up NonStop configuration files as described in this document... then you will see the following results See EMS events as SNMP alerts NonStop server icons in the discovery map detailed integration instructions start SNMP agent and TCP/IP subagent on NonStop servers By default, an SNMP agent is not started on a NonStop server. You can start an SNMP agent and subagent on each TCP/IP stack. The following example shows the contents of an OBEY file named startup.strtsnmp, which starts an SNMP agent process named $zsnmp and a TCP/IP subagent process named $tcpsa on TCP/IP stack $ztc0. Note: The SNMP agent must be software product revision (SPR) level AAK or greater. $SYSTEM STARTUP 22> fup copy startup.strtsnmp clear all stop $zsnmp volume $system.snmptc0 snmpagt /name $zsnmp, nowait, pri 160, cpu 1/0, tcpip^process^name $ztc0 volume $system.startup delay 10 seconds stop $tcpsa tcpipsa /name $tcpsa, nowait, cpu 1/ -a $zsnmp -t $ztc0 -b 0 Note: In this example, the SNMP agent will create an SNMPCTRL file in the $system.snmmptc0 subvolume. create an EMS filter file and start an SNMP distributor The following command starts an EMS distributor, which will convert EMS messages into SNMP traps. In the example, the SNMP agent is named $znsmp, the filter file is named fltsnmp, and the distributor process is $snmpd. emsdist /name $snmpd,nowait,cpu 1/ backup 0, collector $0, type p, textout $zsnmp.#trap, filter fltsnmp An EMS distributor and filter can convert any EMS message into an SNMP trap. A fast way to get started is to create an EMS filter file and then use this filter file in the startup parameters with your EMS distributor. You can use any editor to create a filter file. The following shows a command to copy to the contents of a filter file named fltsnmp. The file will pass processor up and down events as well as disk path up, path down, and path switch events. The subsystem owner (TANDEM) starts in column 1. The subsystem name (CPU, DISK) starts in column 10, the event number starts in column 30, and the rest of the line shows a comment (this must start at column 50 or greater). 4

If you want to restrict the number of dynamic trap destinations, you can manually configure one for OpenView Network Node Manager software. Once you manually configure a trap destination, the SNMP agent will not dynamically add additional trap destinations. Use the following commands to add a trap destination named #nnm at IP-address to the $zsnmp processes and to change the community string to READWRITE. By default, the community string is set to READONLY. The hostaddr contains the IP address of the server running OpenView Network Node Manager software. SCF assume process $zsnmp add trapdest #nnm, network $ztc0, hostaddr , community public stop profile #default alter profile #default, access READWRITE start profile #default start trapdest #nnm start web ViewPoint software on port 280 The following command assumes that the TCP/IP stack is running as process $ztc0. We use port 280 because Network Node Manager software discovers this port. $ztc0 is the default name for the TCP/IP process. run webvpt /name $wvpt nowait/ -p 280 -t $ztc0 noa configure network node manager software to recognize NonStop servers The following procedure enables Network Node Manager software to identify NonStop server systems that are running an SNMP agent. 1. Create the file C:\Program Files\HP OpenView\NNM\symbols\C\computer\computer_nonstop: SymbolType "Computer" : "nonstop" { Filebase "nonstop"; CursorSize 38; Capabilities { isnonstop = 1; } } 5

6 2. Copy the set of GIF files (nonstop.16.gif, nonstop.20.gif, nonstop.26.gif, nonstop.32.gif, nonstop.38.gif, nonstop.44.gif, nonstop50.gif), which are available at to the following two directories: C:\Program Files\HP OpenView\NNM\www\htdocs\bitmaps\C\computer\*.* C:\Program Files\HP OpenView\NNM\bitmaps\C\computer\*.* 3. Add the following line to the C:\Program Files\HP OpenView\NNM\conf\oid_to_sym file: :Computer:NonStop #HP NonStop Server 4a. Create the fields file in: C:\Program Files\HP OpenView\NNM\fields\C\nonstop: Field "isnonstop" { Type Boolean; Flags Capability; } 4b. Add NonStop to C:\Program Files\HP OpenView\NNM\fields\c\ovw_fields. 4c. Add NonStop to c:\program Files\HP OpenView\NNM\fields\c\snmp_fields. 5. Inform Network Node Manager software of the new NonStop capability: ovw -fields 6. Check for syntax errors: ovw -verify 7. Add the following line to the C:\Program Files\HP OpenView\NNM\conf\oid_to_type file: :Compaq:: #HP NonStop Sever 8. Update the database so the new symbols you created appear on the map: ovstop -c -v netmon ovtopofix -u -o >1& more ovstart -v 6

7 ovstatus -c The following procedure allows Network Node Manager software to receive SNMP traps: 1. FTP the emsmiba definition file from $<vol>.zems.emsmiba to the OpenView workstation. 2. Load the SNMP MIB into OpenView workstation: Options->Load/Unload Mibs:SNMP (see figure 4). Figure 4. Screen showing loading instructions. 3. Use the Options->Event Configuration tool to change the way the events are displayed (see figure 5). 7
