Suspending or resuming CES nodes by using GUI

You can suspend or resume CES nodes from the Services > CES Nodes page of the IBM Storage Scale GUI.

Perform the following steps to suspend or resume CES nodes:

  1. Go to Services > CES Nodes page in the IBM Storage Scale GUI.
  2. To suspend a CES node, select the CES node and click Suspend Node. The Suspend Node window appears. Click Suspend Node in the Suspend node window to complete the process. When you suspend a CES node, you can also stop all the CES services on that node.
    Note: You can decide whether to stop CES service when you suspend the node. The CES services continue to run on a suspended node, but since no IP addresses are assigned to the node, they are not involved in any client I/O activity. Stopping CES services when you suspend a node results in terminating all CES services on that node.
  3. To resume a suspended CES node, select the node and click Resume Node. The Resume Node window appears. Click Resume Node in the Resume Node window to complete the process.
    When the node is resumed, the CES IP addresses become active again. You can also start all the stopped service while performing the resume node operation.

    You cannot enable or disable a CES service from the GUI. Use the mmces command in the CLI if you need to enable or disable a CES service in the cluster.
