When VCS Starts

When VCS is started, it checks the state of its local configuration file and registers with GAB for cluster membership. If the local configuration is valid, and if no other system is running VCS, it builds its state from the local configuration file and enters the running state.

If the configuration on all nodes is invalid, the VCS engine waits for manual intervention, or for VCS to be started on a system that has a valid configuration.

See Cluster and system states.

To start VCS

• Run the following command:

  hastart

To start VCS when all systems are in the ADMIN_WAIT state

• Run the following command from any system in the cluster to force VCS to use the configuration file from the system specified by the variable system:

  hasys -force system

To start VCS on a single node

• Type the following command to start an instance of VCS that does not require the GAB and LLT packages. Do not use this command on a multisystem cluster.

  hastart -onenode

To start VCS as a time-sharing process

• Run the following command:

  hastart -ts
