===== Post Installation =====
  
  rm /var/adm/rational/clearcase/no_mvfs_tag


===== Status/Stop/Start/Restart ClearCase =====

  /usr/atria/etc/atria_start status|stop|start|restart


===== Update/Modify Installation =====

To update or modify launch the Installation Manager


  /opt/IBM/InstallationManager/eclipse/launcher


===== Rebuild the MVFS without reinstalling Rational ClearCase =====

Run the command:

   cd /var/adm/rational/clearcase/mvfs/mvfs_src

Clean up the results of previous builds:

   make clean

Build the MVFS modules:

   make 

You will be prompted for the path to the Linux kernel source directory. The default prompt is /lib/modules/`uname -r`/build.

Install the newly built MVFS modules into the proper directory under /lib/modules, so that the MVFS modules will be loaded
into the kernel when Rational ClearCase starts:

   make install

Restart Rational ClearCase.

   /opt/rational/clearcase/etc/clearcase stop
   /opt/rational/clearcase/etc/clearcase start

After the installation process has completed, test that Rational ClearCase has been properly installed by running the cleartool -version command.
You should see output indicating the version of MVFS that has been installed, as in the following example.

   /opt/rational/clearcase/bin/cleartool -version
