Uninstalling in Noninteractive Mode
You must log in to the system with root privileges. You can also open the command prompt as root and run the installer through the command line.
Perform the following step to install the LSI Storage Authority software in noninteractive mode:
msiexec.exe /x <productcode>/qn command to uninstall LSA.
Where <productcode> is a unique product code associated with each LSA installation and <LSA_HOME_PATH> is the location where the LSA is installed.
Example: msiexec.exe /x {20660CCB-7C70-4D61-8D18-FB7FA3C476C9}/qn
Before you begin to uninstall LSA, if any file has been manually copied to the <LSA_HOME> directory by you other than the standard installation package contents, make sure you delete those files. If you fail to remove the files that have been manually copied to the <LSA_HOME> directory, the uninstallation process may fail.
