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: Basic Administration (Solaris 9 or Solaris 10) 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. Add /usr/sbin/ and /usr/cluster/bin/ to the PATH.

   2. Add /usr/cluster/man/ to the MANPATH.

   See your Solaris OS documentation, 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.
