IBM Cluster Systems Management V1.3.2 now extends cluster management
support to Linux on IBM eServer pSeries.

IBM Cluster Systems Management (CSM) helps consolidate the management
of large numbers of IBM pSeries and xSeries servers. Originally
introduced for Linux on xSeries, then AIX on pSeries, CSM is now
available for Linux on pSeries.

CSM is intended to simplify the tasks of installing, operating and
maintaining clusters of servers. It is designed to include remote
hardware control, utilities for administering software updates across all
servers in the cluster, cluster-wide resource monitoring tools and
automatic triggers that can be used to alert system managers or initiate
corrective actions when problems occur.

New for CSM for Linux on pSeries


  • Includes the functionality of CSM 1.3.1 plus install scripts for
    administrators to set up customization during install.

  • Runs on IBM eServer pSeries models 615, 630, 650 and 655, and SuSE
    Linux Enterprise Server (SLES) 8 and Turbolinux Enterprise Server (TLES)
    8.

New for CSM for Linux on xSeries


  • Runs on new hardware IBM eServer xSeries 445 and Bladecenter HS20
    8832

  • Improved installation mechanism for SuSE and SuSE SLES distributions:
    CSM now uses AutoYaST, the native SuSE/SLES installer.

New for CSM for AIX 5L


  • Support for configuring secondary adapters at install time, allowing
    the administrator to set up additional Ethernet adapters: increases
    efficiency and usability by allowing these additional adapters to be set
    up across multiple nodes when the cluster is installed.

  • Use of the AIX geninstall command to directly install the
    CSM management server (instead of the CSM command installms)

  • Increased usability and efficiency of CSM install by using the new
    AIX command nim_master_setup to automate NIM setup

  • Install scripts for administrators to set up any needed customization
    during install





Cluster Systems Management (CSM) can help lower the overall cost of IT
ownership by helping to simplify the tasks of installing, operating, and
maintaining clusters of servers. CSM provides one consistent interface
for managing both AIX and Linux nodes, with capabilities for remote
parallel network install, remote hardware control, and distributed
command execution.

New with CSM V1.4 on AIX 5L and Linux:


  • Optional IBM CSM High Availability Management Server (HA MS) feature
    on Linux or AIX 5L V5.2, which is designed to allow automated failover of
    the CSM management server to a backup management server.

  • Sample scripts for setting up NTP, automounter and network tuning
    (CSM V1.4 on AIX ONLY) configurations to help improve cluster ease of use
    and site customization

  • Capability to copy files across nodes or node groups in the cluster

  • Support for representing additional parts of the cluster as non-node
    devices in the cluster, and allowing the CSM management server to beable
    to show status of these non-node devices as well as to power on/off the
    devices if there is remote power capability.

Specific product enhancements:


  • CSM for Linux on POWER:

    • Support on the pSeries servers* and BladeCenter JS20 running SUSE
      SLES 8 and Red Hat AS 3.0
    • Cluster scaling on each POWER4 Hardware Management Console (HMC) up
      to 32 physical systems and 64 operating system images, and on each
      POWER5 HMC up to 16 physical systems and 64 operating system images
    • A remote console for the JS20 to provide ease of administration and
      RAS
    • Greater install flexibility with ability to install over any Ethernet
      interface

  • CSM for Linux on e325 and xSeries:

    • Support for up to 1024 nodes on xSeries fulfills larger enterprise
      opportunities, situations, and requirements
    • Support for Red Hat Enterprise Linux (EL) 3.0
    • A remote console for the BladeCenter HS20 can provide ease of
      administration and RAS

Programs (PSSP) for AIX and is positioned as a complementary offering to
PSSP and AIX-based clusters. It is aimed at customers who want robust
cluster systems management on an AIX 5L or open, Intel-based server
platform. CSM and the IBM Cluster 1600 or Cluster 1350 are ideal for
high-performance and commercial computing workloads, including
applications in scientific and technical computing, Life Sciences, and
e-business infrastructure (for example, Web serving and
collaboration/e-mail).

CSM delivers a robust, scalable management platform to help ease
administration. It may help reduce life cycle costs. Customers can
manage their AIX 5L or Linux servers from a central location, rather than
having to manage each system individually. The "central location" is a
single point of control known as the management server. It must be a
pSeries machine running AIX V5.2. The machines within the cluster are
referred to as managed nodes and can be pSeries machines running AIX 5.2,
or AIX 5L for POWER V5.1. They can also be xSeries machines running CSM
for Linux.

Customers benefit from IBM's established leadership in
super computing
systems, because the technology and experienced skills from the SP and
AIX platforms are being leveraged on Linux. Customers may be more
willing to adopt Linux in a production environment when it is backed by
superior management software.

a single AIX 5L V5.2 management console can provide management services
to AIX 5L and Linux clients in distributed and clustered configurations.
CSM is also a key element of the IBM eServer Cluster 1600 and Cluster
1350, platforms ideal for workload consolidation or for achieving high
degrees of scalability and performance for applications that take
advantage of clustered systems architectures; for example, computational
modeling in high-performance computing or multi-terabyte data warehouses
in large corporations.

CSM for Linux on pSeries is designed to include existing CSM 1.3.1
function, plus:


  • Runs on new hardware - p615, p630, p650 and p655 - and the software
    Linux distributions SLES 8 and TLES 8.

For both CSM for AIX 5L and CSM for Linux on xSeries, the following
new functions are designed to provide:


  • A new command called csmstat is designed to provide a
    snapshot of the cluster. It can be run across all the nodes in the
    cluster, or for a particular set of nodes or node groups. It will return
    for each node the network reach-ability of the node, power status, status
    of network interfaces on the nodes, and LED/LCD display. For customers
    familiar with PSSP, this functionality is very similar to what the PSSP
    command "spmon -d" was often used for.

  • CSM now provides backup and restore scripts to save and restore
    certain CSM management server data. These scripts can be used in a
    variety of ways, such as setting up new clusters using configuration data
    from existing customers, moving a cluster's management server to a backup
    server, or helping to save certain data prior to a management server
    operating system upgrade and then restoring it.

  • New diagnostic probes to help customers determine if certain things
    are correct before installing the nodes in the cluster. These probes
    help verify that the management server has been set up correctly and that
    the hardware control points, console servers, and associated information
    are all configured correctly.

CSM for Linux on xSeries is designed to provide the following new
function:


  • The install mechanism for SuSE and SuSE SLES distributions has been
    changed. Previously, CSM made use of the open source package System
    Installation Suite (SIS). CSM will now use AutoYaST, the native SuSE/
    SLES installer. (Note that CSM already uses the native install mechanism
    on RedHat - Kickstart).

CSM for AIX 5L new function includes:
