cluster. If a server that is configured in partition mode (with physical or virtual resources) is
part of the cluster, all partitions must be part of the cluster.
Monitoring is much easier to use, and the system administrator can monitor all of the network
interfaces, not just the switch and administrative interfaces. The management server pushes
information out to the nodes, which releases the management server from having to trust the
node. In addition, the nodes do not have to be network-connected to each other. This means
that giving root access on one node does not mean giving root access on all nodes. The base
security setup is all performed automatically at installation time.

The CSM ships with AIX 5L itself (a 60-day Try and Buy license ships with AIX). The CSM
client side is installed automatically and is ready when you install AIX 5L. So, each system or
logical partition is cluster-ready.
The CSM V1.5 on AIX 5L and Linux introduces an optional IBM CSM High Availability
Management Server feature, which is designed to allow automated failover of the CSM
management server to a backup management server. In addition, sample scripts for setting
up Network Time Protocol (NTP), and network tuning (AIX 5L only) configurations, and the
capability to copy files across nodes or node groups in the cluster can improve cluster ease of
use and site customization.
