Shut Down Service Nodes

Root user privileges are required to run xtshutdown. Passwordless ssh must be enabled for the root user from the boot node to all service nodes.
CAUTION: The xtshutdown command does not shut down compute nodes. To shut down the compute and service nodes, see Shut Down the System Using the Automation File.
For information about shutting down service nodes, see the xtshutdown(8) man page.
  1. Modify the /etc/opt/cray/xtshutdown/xtshutdown.conf file or the file specified by the XTSHUTDOWN_CONF environment variable to define the sequence of shutdown steps and the nodes on which to execute them. The /etc/opt/cray/xtshutdown/xtshutdown.conf file resides on the boot node.
  2. If desired, define functions to execute when the system is shut down. Place these functions in the /etc/opt/cray/init-service/xt_shutdown_local file or the file defined by the XTSHUTDOWN_LOCAL environment variable.
  3. Execute xtshutdown. 
    boot# xtshutdown
    After the software on the nodes is shutdown, the administrator can halt the hardware, reboot, or power down.
