Chapter 2 # 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 Installation Cluster Configuration File New Tools ## 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.
