Product Positioning

CSM for AIX 5L and Linux offers a way to manage a collection of AIX or Linux servers (nodes) from a single-point-of-control.

Why should you use CSM?

  • Manageability: May help reduce management costs
  • Consolidate workloads
  • Help reduce complexity
  • Help improve asset utilization
  • Help lower total cost of ownership
  • For Business Intelligence (BI) clusters greater than one node

Functions include automated setup, hardware control, monitoring, and configuration file management. Administrators can manage individual nodes, run commands across nodes or groups of nodes, monitor system resources, and run automated responses to events. CSM is designed to exploit the advanced hardware management features of the servers in the Cluster 1600 or Cluster 1350, or a cluster of xSeries servers.

CSM includes technology derived from IBM Parallel System Support Programs (PSSP) for AIX and is positioned as a replacement offering to PSSP. 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 make administration easier. 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.

Customers can scale their systems incrementally as workload demand increases, without increasing the management complexity.

Customers may be able to 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.

CSM HA MS is positioned for the customer who needs a highly available management server. CSM HA MS is designed to remove the management server as a single point of failure from the cluster.

Description

CSM V1.4.1 is designed to provide simple, low-cost management of distributed and clustered IBM eServer servers. For organizations with both Linux and AIX applications, a single AIX 5L V5.2 or V5.3 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 that are ideal for workload consolidation or for achieving high degrees of scalability and performance for applications that take advantage of clustered systems architectures. Primary examples are computational modeling in high-performance computing or multi- terabyte data warehouses in large corporations.

The CSM licensed products include:

  • CSM for Linux on POWER

  • CSM for Linux on Multiplatforms (xSeries, BladeCenters)

  • CSM for AIX 5L

New with CSM V1.4.1 in all three product offerings:

CRHS

CRHS is a set of software which enhances the ability of the CSM management server to manage pSeries POWER5 hardware. The net gain of this software is that the CSM management server become more of a central point of control in a cluster containing POWER5 HMCs, since more function can be executed and controlled directly from the CSM management server, rather than via the HMC. Some of the features CRHS brings to CSM include:

  • Hardware discovery of HMCs and POWER5 hardware on a cluster network from the CSM Management Server (MS)

  • The ability to assign, from the CSM MS, which HMC controls which POWER5 server

  • The ability to set, change, and distribute server service processor passwords from CSM MS

  • Reduction in the number of HMCs required for failing over to another HMC by allowing you to have one HMC that can be used to fail over any of the systems on the network. The old model was to have duplicate HMCs for each subnet of HMC/servers.

Note: APARs IY69115, IY69116 and IY69117 are required for CRHS.

Install servers

CSM V1.4.1 provides separate install server support allowing node installation services to be off-loaded from the management server onto one or more separate servers. An install server handles installation services such as DHCP, TFTP, PXE, BOOTP, NFS, and other functions required during a network operating system installation of a node. All managed node operating system installations are still initiated using CSM commands from the management server as a central point of control, and the CSM software will automatically distribute the necessary operations to the appropriate install servers. Install servers in homogeneous clusters can improve scalability and node installation performance by distributing the required network services across multiple servers. Install servers in heterogeneous clusters allow CSM to provide node operating system installation for different operating system (OS) distributions within the same cluster.

Mixed clusters

CSM has enhanced its mixed clusters support structure for operating system support. The following lists outline the mixed clusters scenarios supported in CSM 1.4.1.

Clusters managed by pSeries Management Servers running AIX 5L can contain the following:

  • All CSM supported releases of AIX on pSeries managed nodes and up to one of the following:
    • All CSM supported releases of Red Hat on pSeries managed nodes, or
    • All CSM supported releases of Red Hat on xSeries managed nodes, or
    • All CSM supported releases of SUSE SLES on pSeries managed nodes, or
    • All CSM supported releases of SUSE SLES on xSeries managed nodes

Clusters managed by xSeries Management Servers running SUSE SLES can contain any combination of the following:

  • All CSM supported releases of Red Hat on xSeries managed nodes
  • All CSM supported releases of SUSE SLES on xSeries managed nodes

Clusters managed by xSeries Management Servers running Red Hat can contain any combination of the following:

  • All CSM supported releases of Red Hat on xSeries managed nodes
  • All CSM supported releases of SUSE SLES on xSeries managed nodes

Clusters managed by pSeries Management Servers running SUSE SLES can contain any combination of the following:

  • All CSM supported releases of Red Hat on pSeries managed nodes
  • All CSM supported releases of SUSE SLES on pSeries managed nodes

Clusters managed by pSeries Management Servers running Red Hat can contain any combination of the following:

  • All CSM supported releases of Red Hat on pSeries managed nodes
  • All CSM supported releases of SUSE SLES on pSeries managed nodes

CSM now allows managed nodes to be installed with a higher version of an operating system than is installed on the management server. However, the version of CSM on the management server must continue to be as high, or higher, than the version of CSM on the managed nodes.

Implementation documentation of firewalls

CSM support for Firewalls has documented configuration requirements to support a firewall within a CSM Management Domain (MD), such that a firewall host physically and logically separates a MS and its Managed Nodes (MNs).

Support for p5 Virtual I/O servers and I/O server partitions

CSM now supports as a non-node device the p5 Virtual I/O Server. On the p5 system a Virtual I/O Server allows multiple client partitions to share physical resources, such as network adapters and SCSI devices.

Usability enhancements

CSM 1.4.1 provides usability enhancements in the following areas:

  • IP addresses can be used instead of host names working with Linux clusters

  • Commands now accept host groups

  • The systemid command now supports multiple nodes

  • InstallAdapterGateway enhancements

  • There are two new probes

    • Node Install Probe, which will verify all node attributes, OS image data, and node install setup that is required to install a node

    • Install Server Probe, which will verify the install server has been setup correctly

  • CSM has documented the Probe infrastructure and interfaces so customers can now write their own probes for use within CSM.

AIX error log and Linux syslog monitoring

CSM now provides optional monitoring of the AIX Error Log and the Linux Syslog throughout the cluster. A new sensor will be installed on all nodes, and new predefined conditions and responses are available on the management server.

Enhancements for non-root users

CSM now allows non-root users to execute a subset of CSM commands on the management server that normally require root access.

Documentation improvements

The CSM documentation, which previously consisted of a CSM AIX library and a CSM Linux library, has been merged into one library in conjunction with the mixed clusters enhancements. Also, the books have been reorganized to make them more usable.

Specific product enhancements:

  • CSM for Linux on POWER:

    • Support for IBM eServer POWER5 server and virtual I/O environments

    • Support for pSeries POWER4 servers and BladeCenter JS20 running SUSE SLES 8 or 9, and Red Hat EL 3.0 and EL 4.0

    • Support for IBM eServer POWER5 servers running SUSE SLES 9, and Red Hat EL 3.0 or EL 4.0

    • High Availability Management Server (HA MS) feature running SUSE SLES 9, and Red Hat EL 3.0 and EL 4.0

  • CSM for Linux on Multiplatforms:

    • Support for Red Hat EL 3.0 and 4.0

  • CSM for AIX 5L:

    • Support for new POWER5 servers and AIX 5L V5.3

    • HA MS feature supported on AIX 5.3

On all platforms, the optional CSM High Availability Management Server (HA MS) is designed to prevent the management server from being a single point of failure in the CSM cluster. CSM HA MS uses a shared disk to store the CSM management server's data and requires a backup management server with a similar configuration to the primary management server. CSM HA MS is designed to automate failover in response to failure conditions. Failover can also be triggered by the administrator in order to create maintenance windows.

Setting up CSM HA MS can be done at any time during the life of the cluster. While CSM HA MS is expected to only failover CSM management server functionality, you can define pre-and post-scripts to customize the failover. This can allow you to failover other subsystems or data as needed.

To use CSM 1.4.1 Cluster Ready Hardware Server functions, or to use an AIX 5L management server to manage a configuration containing both AIX and multiple Linux nodes of differing achitectures (pSeries or xSeries) or differing operating systems (Red Hat or SUSE SLES), the following CSM for AIX 5L 1.4.1 service is required:

 
Description Required APAR numbers ----------------------------------------------------------- CSM for AIX 5L V5.2 and V5.3 IY69115 RSCT for AIX 5L V5.3 IY69117 RSCT for AIX 5L V5.2 IY69116  

The CSM management server must be running AIX 5L V5.3, or AIX 5L V5.2 with Recommended Maintenance package 5200-04.

The other machines within the cluster are referred to as managed nodes and can be running AIX 5L V5.3, AIX 5L V5.2 with 5200-04 and APARs as previously mentioned, or AIX 5L V5.1 with the 5100-07 Recommended Maintenance package.

They can also be xSeries machines running CSM for Linux. V1.4.1 (see the following section).

Certain CSM for AIX 5L. functions require non-IBM software. The following non-IBM software is required:

  • openCIMOM Version 0.7 or 0.8

    This should be used if you want to perform remote hardware control operations for pSeries servers attached with an HMC. Obtain the software from the "AIX toolbox for Linux applications" CD (refer to Software Announcement 201-090, dated April 17, 2001), or to obtain the download Web site address, visit:

    https://techsupport.services.ibm.com/server/cluster

CSM High Availability Management Server (HA MS) feature (all platforms):

CSM HA MS supports the following operating systems:

  • Red Hat EL AS 3 or EL AS 4 on xSeries
  • SUSE SLES 9 on xSeries
  • Red Hat EL AS 3 or EL AS 4 on POWER
  • SUSE SLES 9 Linux on POWER
  • AIX 5.2 Maintenance Level 5200-04, or higher
  • AIX 5.3

CSM HA MS is also supported on IBM eServer POWER5 servers running SuSE. 9, and Red Hat EL 3.0 and EL 4.0

Note: The shared disks supported by HA MS do not always support the above operating systems. Use of HA MS is restricted to operating systems supported by the chosen shared disk.

CSM HA MS also requires that CSM V1.4.1 be installed on both management servers. CSM HA MS does not require the installation of any other HA product. All required software is included in CSM and HA MS.

Planning Information

Customer Responsibilities

Not applicable.

Compatibility

  • CSM for Linux on POWER 1.4.1 is a functional enhancement and replacement of CSM for Linux on POWER V1.4.0.
  • CSM for Linux on Multiplatforms 1.4.1 is a functional enhancement CSM for Linux on Multiplatforms V1.4.0.
  • CSM for AIX 5L 1.4.1 is a functional enhancement and replacement of CSM for AIX 5L V1.4.0.

CSM requires that the CSM administrative network be an Ethernet network. However, CSM can tolerate any network architecture (for example, but not limited to, Infiniband, Myrinet, GigE) as a secondary network to the cluster.

Limitations

Scaling limitations

Your CSM cluster must adhere to all of the following applicable limits. Your cluster size limit will be the smallest number of all applicable limits. Support for clusters above such limits will be considered via Special Bid.

Maximum number of operating system images:

For supported xSeries based Linux systems the CSM scaling limit is 1024 operating system images.

For supported pSeries AIX or Linux, systems, the scaling limit is 128 operating system images.

For combined environments, the limit is 1024 operating system images, with no more that 128 of those images being on pSeries systems.

Cluster limits for all platforms and situations:

 
Situation Maximum number -------------------- ------------ LPARs per Cluster 128 Number of LPARs per HMC 64 Number of POWER4 servers per HMC 32 Number of POWER5 servers per HMC 32

  • Red Hat EL 3.0 (AS/ES/WS)
  • Red Hat EL 4.0 (AS/ES/WS)
  • SUSE SLES 8
  • SUSE SLES 9

Note: Combinations of CSM with Linux operating systems are dependent upon specific hardware models. To see if CSM runs on the desired combination of Linux Distribution and hardware, refer to the Frequently Asked Questions section at:

http://techsupport.services.ibm.com/server/csm/documentation

  • There is limited hardware control support for the x440.

  • Multiple install servers are only supported for installing nodes with CSM and Red Hat Linux.

  • Professional versions of Linux are not supported with CSM V1.4.1.

  • For xSeries, if you do not have a terminal server, the remote console function (rconsole) will not work and automatic MAC address collection will not work for the full installation of Linux nodes.

Note: Technical support applies only to the IBM licensed products mentioned previously. If these products are running on an operating system (or with a corequisite, prerequisite product) that is no longer supported, IBM technical support may be limited to defects that can be replicated on supported environments (that is, supported versions of the operating systems).

CSM for AIX 5L:

  • AIX 5L V5.2 or V5.3 is required for the cluster management server. The management server needs to be at the highest operating sytem level of any node in the cluster.
  • CSM for AIX 5L does not run on the RS/6000 SP Switch nor SP Switch2.
  • PSSP and CSM will not coexist in the same cluster.
