Installation, Configuration, and Administration

For a summary of the changes to the installation process, the configuration files, and the system administration tools, see the following sections:

Supported Cluster Configurations

Like the previous version of the Foundation Services, the current patch level of the product supports cluster configurations of two master-eligible nodes and a number of master-ineligible nodes. The limitation of 10 master-ineligible nodes no longer exists. For information about the cluster size supported, see the Netra High Availability Suite Foundation Services 2.1 6/03 Release Notes. You can also now have a mix of diskless and dataless nodes in a single cluster.

The following new hardware items are now supported with the current patch level of the Foundation Services.

  • Netra CT 820 server

  • Netra 240

  • Sun Fire™ V240

  • Sun Fire V210

  • Sun StorEdge 3310 disk array for single attachment

For a full list of supported hardware and example cluster configurations, see the Netra High Availability Suite Foundation Services 2.1 6/03 Hardware Guide.

Installation

This section summarizes the changes to the packages that are installed on a cluster, and the changes to the installation processes.

Patches

The Foundation Services 2.1 6/03 distribution contains the following patches:

114175-0x

Patch for master-eligible nodes

115606-0x

Patch containing enhancements to services for all cluster nodes

115644-0x

Patch for nhinstall tool

When you install these patches, you must also install patch 116710. This patch is not part of the Foundation Services 2.1 6/03 distribution and is only available to Foundation Services customers. For information about the availability of this patch, ask your Sun support contact.

For a full list of the Foundation Services 2.1 6/03 packages and patches, see the Netra High Availability Suite Foundation Services 2.1 6/03 README.

The nhinstall Tool

The nhinstall tool has been adapted to include the enhancements made to the Foundation Services 2.1 6/03. For information about the enhancements, see Chapter 3, Service Enhancements. For information about how to install a cluster using the nhinstall tool, see the Netra High Availability Suite Foundation Services 2.1 6/03 Custom Installation Guide.

The nhinstall tool has been adapted to include the following enhancements:

  • A choice of method by which the tool installs patches

  • Ability to configure DHCP on the local file system of master-eligible nodes during diskless node installation

  • Ability to use a router other than the installation server. By default the router is the installation server

  • Choices on how you install the Solaris operating system:

    • Installing a different Solaris package set on diskless nodes to from the one you install on the master-eligible nodes. Both package sets must be from the same Solaris distribution. For more information, see the nodeprof.conf(4) and diskless_nodeprof.conf(4) man pages.

    • Identifying the appropriate OS profile to be installed even when the version of the Solaris operating system cannot be automatically detected.

    • Installing a different version of the Solaris operating system on diskless nodes to the one you install on the master-eligible nodes.

Manual Installation

The manual installation procedure has been adapted to support the installation of diskless and dataless nodes in a single cluster.

All of the new features that are automatically installed by the nhinstall tool can be installed manually. For information about the manual installation procedure, see the Netra High Availability Suite Foundation Services 2.1 6/03 Custom Installation Guide. For a complete list of packages to install, see the Netra High Availability Suite Foundation Services 2.1 6/03 README.

Cluster Configuration File

The Foundation Services are configured by the nhfs.conf file. The following new parameters have been defined in the nhfs.conf file:

RNFS.SyncType

Control of the replication mode. This impacts the time it takes for a full synchronization of the vice-master and master disks.

For further information, see Reduced Duration of Disk Synchronization.

Cluster.DataManagementPolicy

Set the data management policies to be Integrity, Availability, or Adaptability.

For further information, see Data Management Policy.

CMM.MasterLoss.Detection

Permit the diskless and dataless nodes to stay up even when there is no master node in the cluster.

For further information, see Masterless Cluster.

RNFS.CheckReplicatedSlices

Continuously scan the state of replicated slices.

For further information, see Sanity Check of Replicated Slices.

RNFS.EnableSync

Delay the start of disk synchronization.

For further information, see Delayed Synchronization.

RNFS.SerializeSync

Synchronize the master and vice-master disks one slice at a time.

For further information, see Serialized Slice Synchronization.
