HP Systems Insight Manager 5.2 Update 2 Technical Reference Guide

• Router A networking device used to route network packets.
• Server A computer on a network that is dedicated to a particular purpose. For example, saving files,
running print jobs, or housing a database server.
• Shared Resource Domain A collection of compartments, all of the same type, that share system
resources. The compartments can be npars, vpars, psets, or fss groups.
• Storage Device A disk drive array that usually supports RAID levels and is accessed over a Fibre
Channel Storage Area Network (SAN).
• Switch A network device, similar to a router, that uses hardware-based switching technology to route
packets quickly on the network.
• Tape library A storage device that contains one or more tape drives, usually for backup purposes.
• Thin client A remote system connecting to a terminal server, which is a computer that has no disk or
local storage and enables you to connect through terminal server packages to a central server or remote
desktop.
• Uninterruptible Power Supply (UPS) A battery backup that provides power for servers or other
computers.
• Unknown In HP SIM, Unknown is a status indicating that none of the built-in or System Type Manager
(STM) based tasks could identify the system. However, some management protocol was detected on
the system. Servers might be listed as Unknown for the following reasons:
• You must be able to ping the system from the server where HP SIM is running. You can issue the
ping command from a command or terminal window, or you can ping from HP SIM by selecting
the unknown server, selecting the Diagnose and Ping options, and then following the on-screen
instructions.
• Try running the Configure or Repair Agents settings tool located in the Configure menu.
• If the system supports SNMP, it might be that the type is new or is a third-party system that is not
identified by default. See “Global protocols” and “System tab” for more information. You can use
the System Type Manager (STM) tool to add a new type. See “Creating STM rules” for more
information.
• Community strings in HP SIM must match the ones used for the remote device. Ensure that HP SIM
and the systems to be identified are using the same community string. Note that community strings
are case-sensitive. From HP SIM, select Options→Protocol Settings, and then select Global
Protocol Settings or System Protocol Settings to change the community strings.
• In Windows NT and Windows 2000, one community name on the system must be set to Read
Create . You are not required to use this community string in HP SIM (a community string set to
Read is all that is required). The Management Agents connect to themselves using Simple Network
Management Protocol and require one string set to Read Create .
• The HP SIM system must be allowed to make SNMP requests to the managed systems. Ensure that
the Simple Network Management Protocol security settings are not preventing these requests. In
Windows NT and Windows 2000, ensure that the Allow SNMP packets from any host is
selected, or that the address of the HP SIM server is in the list of allowed hosts.
• If you are using IP-specific security, localhost (127.0.0.1) must also be allowed to make SNMP
requests to the host. The localhost entry enables the Management Agents to connect to themselves
using SNMP.
• The ProLiant Management Agents must be installed and running properly on the ProLiant servers
you are managing. For Windows systems, look at the Event Log to verify that the Management
Agents are running (you should see a few Agents started messages and no errors).
• Routers and switches in the network must allow SNMP traffic to pass on UDP port 161 or 162.
• Unmanaged A system type that was found with an IP address, but without any detected management
protocols. If this is not the expected type, ensure that the Web-Based Enterprise Management user name
and password, or the SNMP community name, is correct. Install agents if possible (for example, for
