Managing the Compaq ProLiant Clusters HA/F100 and HA/F200 5-3 Managing Hardware Components of Individual Cluster Nodes Compaq Insight Manager has been enhanced to operate with the Compaq ProLiant Clusters HA/F100 and HA/F200. Compaq Insight Manager XE allows you to view and manage servers and their components, and it now allows you to view two cluster nodes as a single cluster entity. A comprehensive overview of the cluster capabilities of Compaq Insight Manager is presented later in this chapter. Compaq Insight Manager XE is a product for systems administration and management. Compaq Insight Manager XE, with the Cluster Monitor component, is a Web-based subsystem that monitors the operation of Compaq servers and storage devices configured as Microsoft NT clusters. Cluster Monitor has been designed to improve Microsoft Cluster Server (MSCS) cluster administration and control, and it relies heavily on the Compaq Insight Manager Web-enabled agents (as well as other agents) for basic information about system health. A full description of the Compaq Insight Manager XE capabilities is included later in this chapter. Managing Network Clients Connected to a Cluster An important aspect of managing network clients is to inform the users that their applications are now running on a cluster. Since users will experience some disruption of service and, possibly, a performance degradation during failover, they might become concerned about the availability and stability of their applications. As the cluster is initially brought into a production environment, explain the effects a cluster will have on the users' information systems needs. When a failover or failback event occurs, the users may be unable to access their application and/or data for a brief period. Users who have been properly forewarned of the effects of operating in a clustered environment will more readily recognize when a failover or failback event is occurring or has occurred.

Managing Hardware Components
of Individual Cluster Nodes
Compaq Insight Manager has been enhanced to operate with the Compaq
ProLiant Clusters HA/F100 and HA/F200. Compaq Insight Manager XE
allows you to view and manage servers and their components, and it now
allows you to view two cluster nodes as a single cluster entity. A
comprehensive overview of the cluster capabilities of Compaq Insight
Manager is presented later in this chapter.
Compaq Insight Manager XE is a product for systems administration and
management. Compaq Insight Manager XE, with the Cluster Monitor
component, is a Web-based subsystem that monitors the operation of Compaq
servers and storage devices configured as Microsoft NT clusters. Cluster
Monitor has been designed to improve Microsoft Cluster Server (MSCS)
cluster administration and control, and it relies heavily on the Compaq Insight
Manager Web-enabled agents (as well as other agents) for basic information
about system health. A full description of the Compaq Insight Manager XE
capabilities is included later in this chapter.
Managing Network Clients Connected
to a Cluster
An important aspect of managing network clients is to inform the users that
their applications are now running on a cluster. Since users will experience
some disruption of service and, possibly, a performance degradation during
failover, they might become concerned about the availability and stability of
their applications. As the cluster is initially brought into a production
environment, explain the effects a cluster will have on the users’ information
systems needs.
When a failover or failback event occurs, the users may be unable to access
their application and/or data for a brief period. Users who have been properly
forewarned of the effects of operating in a clustered environment will more
readily recognize when a failover or failback event is occurring or has
occurred.
