Rs/6000 Cluster Technology (Rsct) - IBM RS/6000 SP Handbook

PSSP comes with login control for blocking unauthorized user or group
access to a specific SP node or a set of nodes.
It offers consolidated accounting for centralizing records at the node level (for
tracking use by wall clock time rather than processor time) and for gathering
statistics on parallel jobs.
Administrative tools of PSSP:
SP Task Guides
SP Perspectives
Centralized Management Interface

9.1.2 RS/6000 cluster technology (RSCT)

RS/6000 cluster technology gives the SP systems high availability, online
monitoring and automatic recovery actions on clustered nodes. It does this by the
use of three distributed subsystems.
RSCT's subsystems:
Topology Services
Group Services
Event Management Monitors hardware and software resources in the SP and
Online assistance designed to walk you through complex or
infrequently performed tasks. Task Guides do not simply list the
required steps; each Guide actually performs the steps for you,
automating the steps to the highest degree possible and prompting you
for input only when absolutely necessary. You might recognize them as
wizards.
A set of graphical user interfaces (GUI's) which can simplify
administrative work.
Menu-based interface for system management commands, as well as
command line equivalents.
Maintains availability information regarding nodes and
network adapters. Therefore seamless takeover of
functions in the event of a node failure is possible.
Provides services for synchronization and coordination of
recovery actions of other subsystems.
notifies an interested application or subsystem when the
state of the resource changes. Resources on any node in
the SP can be monitored from any other node.
