System shared storage drive cage area supports up to six 1-inch
Wide Ultra2 SCSI drives.
Each server node supports up to six drives.
See the documentation that came with the Compaq ProLiant CL380 for more
information and a complete list of features.
Cluster Integrity Serial Cable
The CI serial cable is required to prevent a split-brain condition. Split-brain
occurs when both nodes in a two-node cluster try to operate as the root node.
Since the active root node mounts the root file system and runs several critical
cluster-wide functions, having two nodes trying to behave as the root node is
undesirable.
NOTE: The CI serial cable may be referred to as the split-brain avoidance (SBA) serial
cable in UnixWare software and documentation.

of each server node in the Compaq ProLiant CL380. This NIC enables the
cluster interconnect, which is precabled in the ProLiant CL380.
NOTE: The cluster interconnect may be referred to as the cluster heartbeat cable in
ProLiant CL380 documentation.
The cluster nodes use the cluster interconnect to support the single-system
image capabilities of the cluster, including:
I Cluster-wide file system
I Cluster-wide process management, migration, and load balancing
I Cluster-wide networking and Cluster Virtual IP (CVIP)
I Cluster-wide system administration and management
Refer to the documentation that came with the Compaq ProLiant CL380 for
more information on the cluster interconnect.
Local Area Network Connection
A Compaq NC3123 Fast Ethernet NIC PCI 10/100 WOL NIC comes
preinstalled in slot 1 of each server node in the Compaq ProLiant CL380.

nodes within the cluster appear to Compaq Insight Manager as separate
UnixWare 7 systems.
Compaq Insight Manager Overview
Compaq Insight Manager is the Compaq console-based application for
managing networked devices. Compaq Insight Manager provides intelligent
monitoring and alerting capabilities for the critical systems in a distributed
enterprise.
Compaq Insight Manager consists of a console application and a set of server-
or client-based management data collection agents. Key subsystems are
designed to make system health, configuration, and performance data available
to the agent software. The agents act upon data by initiating SNMP alarms in
the event of faults and by providing updated management information.
Compaq Insight Manager is located on the Compaq Management CD. Install
Compaq Insight Manager on a Win32 desktop computer using the instructions
provided on the CD.
NOTE: Information on the Shared Storage RAID Controller CR3500 is only available
through the web-enabled agents used with Compaq Insight Manager XE.

Clusterized Compaq Management Agents
TM
Compaq Management Agents running on a SCO UnixWare 7 NonStop
Clusters system support the same client-server interface as is supported on a
single server SCO UnixWare 7 system. The client-server interface for Compaq
Insight Manager is SNMP-based, which allows ProLiant servers and clusters
to be managed by other network management client software.
The Compaq Management Agents are installed during the Quick Install and
are clusterized to allow proper operation within a Compaq ProLiant Cluster.
Each node has its own set of the clusterized agents. The agents on a specific
node are associated with the primary physical IP address of that node and
allow access to information regarding that node.
NOTE: The clusterized agents are only accessible through the primary physical IP address
for each node.
Compaq Insight Manager XE Support
Compaq Management Agent software runs on ProLiant Cluster servers and
interfaces to the Compaq Insight Manager XE management server using
SNMP and HTTP messaging. Compaq Insight Manager XE gives system
