The patch fixes the following installer issues: Issue 1: OS: All supported platforms Products: VCS, SFHA Etrack Incidents: 2324154, 2368684, 2275547 Problem statement: During upgrade of a one-node cluster from 5.1SP1 to 5.1SP1RP1 using responsefile, if VCS is not running before upgrade, then the installer will overwrite the main.cf file, since it fails to detect that VCS was previously configured. The patch also provides a new CLI option, nostart, which allows processes to not be started after RP upgraded. Issue 2: OS: All supported platforms Products: VCS, SFHA Etrack Incidents: 2324154, 2368684, 2275547 Problem statement: During upgrade of a one-node cluster from 5.1SP1 to 5.1SP1RP1, if VCS is running with -onenode option, then installer should detect it as a single-node cluster even if llttab, llthost, or gabtab files exist.
