Stopping a service

Some maintenance procedures require you to stop a single service while keeping other services on the grid node running. Only stop individual services when directed to do so by a maintenance procedure.

Before you begin

You must have the Passwords.txt file.

About this task

When you use these steps to "administratively stop" a service, Server Manager will not automatically restart the service. You must either start the single service manually or restart Server Manager.

If you need to stop the LDR service on a Storage Node, be aware that it might take a while to stop the service if there are active connections.

Steps

  1. From the service laptop, log in to the grid node:
    1. Enter the following command: ssh admin@grid_node_IP
    2. Enter the password listed in the Passwords.txt file.
    3. Enter the following command to switch to root: su -
    4. Enter the password listed in the Passwords.txt file.
    When you are logged in as root, the prompt changes from $ to #.
  2. Stop an individual service: service servicename stop
    For example:
    service ldr stop
    Note: Services can take up to 11 minutes to stop.
  3. Log out of the command shell: exit
