The install_directory/rt_name/pkg directory contains a Solaris package. The name of the package is a concatenation of the vendor name and the application name, for example, SUNWftp. The Makefile in the install_directory/rt_name/src directory supports creation of a new package. For example, if you make changes to the source files and recompile the code, or make changes to the package utility scripts, use the make pkg command to create a new package.
Run the removert_name script from one node of the cluster before running pkgrm from any node.
Run pkgrm from one node of the cluster, which takes care of all necessary clean up, then run pkgrm from the remaining nodes, simultaneously if necessary.
If pkgrm fails because you attempt to run it simultaneously from multiple nodes, run it again from one node then run it from the remaining nodes.
