3.5 Starting the Cluster

The following procedure describes how to start the cluster if it was stopped earlier for cabling an additional rack.

Note:

• Oracle recommends you start one server, and let it come up fully before starting Oracle Clusterware on the rest of the servers.

• It is not necessary to stop a cluster when extending Oracle Exadata Database Machine Half Rack to a Full Rack, or a Quarter Rack to a Half Rack or Full Rack.

1. Log in as the root user on the original cluster.

2. Start one server of the cluster.

   # Grid_home/grid/bin/crsctl start cluster
   

3. Check the status of the server.

   Grid_home/grid/bin/crsctl stat res -t
   

   Run the preceding command until it shows that the first server has started.

4. Start the other servers in the cluster.

   # Grid_home/grid/bin/crsctl start cluster -all
   

5. Check the status of the servers.

   Grid_home/grid/bin/crsctl stat res -t
   

   It may take several minutes for all servers to start and join the cluster.
