2. - ## Stopping the Cluster To upgrade the cluster, you stop the cluster on each node and then shut down each node in the cluster. When you reboot these nodes to install the Foundation Services 2.1 6/03 software, they will run only the Solaris operating system and not the Foundation Services. ### To Stop the Cluster As superuser, log in to a diskless node or dataless node in the cluster. Create the `/etc/opt/SUNWcgha/not_configured` file on the node. For the dataless node, create the `not_configured` as follows:
         # touch /etc/opt/SUNWcgha/not_configured
   - For the diskless node, log in to the master node and create the `not_configured` file as follows:
         # touch /export/root/diskless-node-name/etc/opt/SUNWcgha/not_configured
3. Reboot the node.
       # init 6
The node boots and starts up without starting the Foundation Services. Repeat Step 1 through Step 3 on each diskless or dataless node in the cluster. Log in to the vice-master node as superuser. Repeat Step 2 and Step 3 on the vice-master node. Log in to the master node as superuser. Repeat Step 2 and Step 3 on the master node.
