The procedure How to Install Cluster Control Panel Software on an Administrative Console in Sun Cluster Software Installation Guide for Solaris OS contains the following unnecessary steps and one inaccuracy:
You do not need to use the pkgadd command to install the Cluster Control Panel package SUNWccon or to install the documentation packages. You can pick these packages from the list provided by the installer program. Ignore Step 12 and Step 14 of the procedure.
You do need to use the pkgadd command to install the man page package, SUNWscman. The installer program does not include that package in the list of software packages that it can install. Ignore Step 9 of the procedure.
