   # /etc/init.d/llt start

   If LLT is configured correctly on each node, the console output resembles:

   Loading LLT Driver...

   LLT: loading module...
   Loaded   kernel_version on kernel kernel_version
   LLT: configuring module
   where, kernel_version is the kernel version 
   of the Linux operating system

2. On each node, run the following command to verify that LLT is running:

   # /sbin/lltconfig
   LLT is running

To start GAB

   For RHEL 7, SLES 12, and supported RHEL distributions:

   # systemctl start gab

   For earlier versions of RHEL, SLES, and supported RHEL distributions:

   # /etc/init.d/gab start

   If GAB is configured correctly on each node, the console output resembles:

   GAB: Starting
   GAB: Starting Done

2. On each node, run the following command to verify that GAB is running:

   # /sbin/gabconfig -a

   Port a gen a36e0003 membership 01

To start VCS

• On each node, type:

  For RHEL 7, SLES 12, and supported RHEL distributions:

  # systemctl start vcs

  For earlier versions of RHEL, SLES, and supported RHEL distributions:

  # /etc/init.d/vcs start

  If VCS is configured correctly on each node, the engine log file at /var/VRTSvcs/log/engine_A.log resembles:
