    Sun Cluster 3.2 – Introduction 

    First a introduction to the Sun Cluster 3.2 system, a cluster consist of two or more nodes, that work together in a single continuously available system to provide applications, system resources and data to end users. Each node in a cluster is a fully functional standalone system but when in a cluster the nodes will communicate via a interconnect and work together as a single entity to provide increased availability and performance, however this does come with additional costs.

    The biggest decision to make it that does the application need to be clustered, you can quite easily make a single server high available by making all SPOF (Single Points Of Failure) are eliminated (additional power, power supplies, disk mirroring, etc). This setup would be more than adequate for most Enterprise applications. However there are times when the additional cost of a cluster solution can be justified. (More …)

    Sun Cluster 3.1 Overview 

    Sun Cluster Features

    • up to 8 nodes
    • Cluster filesystem allows mounting of cluster-wide file systems (UFS) / (HSFS), allowing concurrent continuous access to file systems from any node
    • Global device access, sun cluster can access disk devices, tapes devices and cdroms from any node within the cluster
    • Cluster networking (shared address), while each node retains its own publicly accessible internet protocol (IP) address, a global IP address can be configured for the applications on the cluster, where the data service requests received through the global address are distributed are distributed to different nodes in the cluster based on a selected load balancing policy.

    Solaris Hard Disk Upgrade 

    This web page details how to upgrade a pair of mirrored 18GB disks to 146GB disks that use ODS, although I have detailed the system spec’s you can use this document for any other ODS configuration you have. One point I will make is that I will NOT be extending any of the filesystems, you can use the extra space to breakup the existing filesystem if required.

    The following is what I have

    • One V210 Sun server
    • Solaris 8 (02/04) not patched
    • Two 18GB disks mirrored via ODS (the ones we will be upgrading)
    • Two new shiny 146GB disks
    • 4 filesystems including swap (/, /var, /opt and swap), I will not be extending these
    • 4 metadevices (d0, d10, d30 and d40)

    Solaris X86 installation via PXE, TFTP and DHCP 

    Booting Solaris X86 via PXE

    As long as the hardware supports PXE (Preboot Execution Environment) as server can be booted and installed from the network. For standard Sparc servers the normal method of setting up a jumpstart is the best forward, but for X86 clients PXE is the way to go.

    The steps in oder to get a client to boot are as follows:

    • Setup the TFTP server
    • Setup the DHCP server

    Solaris SMF 

    Solaris 10 Services

    There is a new feature to the way Solaris 10 handles services, this feature is called Service Management facility (SMF).

    Terminology

    Fault managed resource identifiers (FMRI) identifies services

    svc :/system/system- log:default

    svc: Service type
    /system/system-log Name
    :default Instance

    The repository is the source for all known services on the system, it imports the service manifest into the database and then never references the manifest again.
