How to Install Sun Cluster Software on a Single-Node Cluster

Perform this task to install Sun Cluster software and establish the cluster on a single node by using the scinstall command. See the scinstall(1M) man page for details.

You cannot use SunPlex Manager or the interactive form of the scinstall utility to install Sun Cluster software on a single-node cluster.

The scinstall -iFo command establishes the following defaults during installation.

• Creates the required device IDs

• Uses the default /globaldevices file system, unless the global-devices file system is specified with the -G option

• Establishes a default cluster name, which is the same as the name of the node being installed, unless the clustername is specified with the -C option

Some steps that are required for multinode cluster installations are not necessary for single-node cluster installations. When you install a single-node cluster, you do not need to perform the following steps:

• You do not need to configure quorum.

• You do not need to configure interconnect adapters or junctions.

If you anticipate eventually adding a second node to your cluster, you can configure the transport interconnect during initial cluster installation. The transport interconnect is then available for later use. See the scinstall(1M) man page for details.

1. Ensure that the Solaris operating environment is installed to support Sun Cluster software.

   If Solaris software is already installed on the node, you must ensure that the Solaris installation meets the requirements for Sun Cluster software and any other software that you intend to install on the cluster. See How to Install Solaris Software for more information about installing Solaris software to meet Sun Cluster software requirements.

2. Become superuser on the cluster node to install.

3. Insert the Sun Cluster 3.1 10/03 CD-ROM into the CD-ROM drive of the node to install and configure.

   If the Volume Management daemon vold(1M) is running and configured to manage CD-ROM devices, it automatically mounts the CD-ROM on the /cdrom/suncluster_3_1_u1 directory.

4. Change to the /cdrom/suncluster_3_1/SunCluster_3.1/Sol_ver/Tools directory, where ver is 8 (for Solaris 8) or 9 (for Solaris 9) ).

   The following example uses the path to the Solaris 8 version of Sun Cluster software.

   # cd /cdrom/suncluster_3_1_u1/SunCluster_3.1/Sol_8/Tools

5. Install the Sun Cluster software and necessary patches by using the scinstall command.

   # ./scinstall -iFo -M patchdir=dirname

   -i

   Specifies the install form of the scinstall command. The scinstall command installs Sun Cluster software and initializes the node as a new cluster.

   -F

   Establishes the node as the first node in a new cluster. All -F options can be used when installing a single-node cluster.

   -o

   Specifies that only one node is being installed for a single-node cluster. The -o option is only legal when used with both the -i and the -F forms of the command. When the -o option is used, cluster installation mode is preset to the disabled state.

   -M patchdir=dirname[[,patchlistfile=filename]]

   Specifies the path to patch information so that the specified patches can be installed by using the scinstall command. If you do not specify a patch-list file, the scinstall command installs all the patches in the directory dirname, including tarred, jarred, and zipped patches.

   The -M option is not required with the scinstall -iFo command. The -M option is shown in this procedure because it is the most efficient method of installing patches during a single-node cluster installation. However, you can use any method that you prefer to install patches.

6. Reboot the node.

   The reboot after Sun Cluster software installation establishes the node as the cluster.

7. Verify the installation by using the scstat command.

   # scstat -n

   See the scstat(1M) man page for details.

8. Set up the name-service look-up order.

   Go to How to Configure the Name-Service Switch.

You can expand a single-node cluster into a multinode cluster by following the appropriate procedures provided in “Adding and Removing a Cluster Node” in Sun Cluster 3.1 10/03 System Administration Guide.
