Starting VCS

You can start VCS using one of the following approaches:

• Using the installvcs -start command
• Manually start VCS on each node

To start VCS

1. To start VCS using the installvcs program, perform the following steps on any node in the cluster:
   • Log in as root user.
   • Run the following command:

     # /opt/VRTS/install/installvcs -start

2. To start VCS manually, run the following commands on each node in the cluster:
   • Log in as root user.
   • Start LLT and GAB. Start I/O fencing if you have configured it.

     Skip this step if you want to start VCS on a single-node cluster.

      

     LLT	# /etc/init.d/llt.rc start # /etc/init.d/llt start
     GAB	# /etc/init.d/gab.rc start # /etc/init.d/gab start
     I/O fencing	# /etc/init.d/vxfen.rc start # /etc/init.d/vxfen start

   • Start the VCS engine.

     # hastart

     To start VCS in a single-node cluster, run the following command:

     # hastart -onenode

     See Starting the VCS engine (HAD) and related processes

3. Verify that the VCS cluster is up and running.

   # gabconfig -a

   Make sure that port a and port h memberships exist in the output for all nodes in the cluster. If you configured I/O fencing, port b membership must also exist.
