How to Set Up the Root Environment

In a Sun Cluster configuration, user initialization files for the various shells must verify that they are run from an interactive shell. The files must verify this before they attempt to output to the terminal. Otherwise, unexpected behavior or interference with data services might occur. See “Customizing a User's Work Environment” in System Administration Guide, Volume 1 (Solaris 8) or “Customizing a User's Work Environment” in System Administration Guide: Basic Administration (Solaris 9) for more information.

Perform this procedure on each node in the cluster.

1. Become superuser on a cluster node.

2. Modify PATH and MANPATH entries in the .cshrc or .profile file.

   1. Set the PATH to include /usr/sbin/ and /usr/cluster/bin/.

   2. Set the MANPATH to include /usr/cluster/man/.

   See your volume manager documentation and other application documentation for additional file paths to set.

3. (Optional) For ease of administration, set the same root password on each node, if you have not already done so.

4. Install Sun Cluster 3.1 9/04 data-service software packages.

   • To use the scinstall utility, go to How to Install Data-Service Software Packages (scinstall).

   • To use the installer program, go to How to Install Data-Service Software Packages (installer).
