Remove the Host Name from the grid.hosts File

The host name for the machine to remove must be removed from the /opt/TKGrid/grid.hosts file. (The path might be different for your deployment.)
To remove the host name:
  1. Log on to the root node for the deployment as the root user or the user ID that installed the High-Performance Analytics Environment.
  2. Edit the /opt/TKGrid/grid.hosts file and delete the line that includes the host name to remove. Save and close the file.
  3. Copy the updated grid.hosts file to the same location on all the machines in the cluster. You can use the simcp command to perform this task:
    /opt/TKGrid/bin/simcp /opt/TKGrid/grid.hosts /opt/TKGrid
If your deployment uses the SAS High-Performance Computing Management Console, remove the host name from the /etc/gridhosts file, too.
