Preconditions

Ensure that the conditions described below are in effect before proceeding with the SCI setup procedure.

SCI Network Hardware Must Be Installed

The SCI network hardware must already have been installed.

ClusterTools 3.0 Software Must Be Installed

The Sun HPC ClusterTools 3.0 software must be installed on the cluster--either on an NFS server or locally on each node. If this has not yet been done, refer to the Sun HPC ClusterTools 3.0 Installation Guide for instructions.

If you will be using the LSF suite as the cluster's workload manager, the LSF components must be installed before the ClusterTools software.

Verify that the following Sun HPC ClusterTools 3.0 packages are present.

• SUNWsci

• SUNWscid

• SUNWscidx - required only on clusters with 64-bit Solaris 7

• SUNWsma

• SUNWsmax - required only on clusters with 64-bit Solaris 7

• SUNWrsmop

• SUNWrsm

These SCI and RSM packages may not be present if, during installation of the ClusterTools 3.0 software, the installer responded "No" when asked if SCI packages should be installed. If they are not present, they must be installed.

The installation GUI (graphical user interface) includes an option for installing the SCI-related packages exclusively. See the Sun HPC ClusterTools 3.0 Installation Guide for more information.

If any of these packages were installed from another source, you must remove them and install the packages provided on the Sun HPC ClusterTools 3.0 software release.

Caution for NIS+ Users

sm_config may have trouble contacting other node in the cluster in an NIS+ environment. By default, the NIS+ version of /etc/nsswitch.conf specifies the services entry as: nisplus [NOTFOUND=return] files. Since the /etc/services file is modified and used by SUNWsma and other packages, the /etc/nsswitch.conf entry should be as follows:

services:   files nisplus 

Place the term files first before other entries.
