Unfreezing a service

When your maintenance shutdown is complete, you may want to unfreeze a service, enabling it to receive or release slots as required.

Before you begin

  • You must be a cluster administrator or have the Services Control permission to unfreeze a service.
  • The service must be in the FROZEN state.

About this task

While you can usually unfreeze a service from the cluster management console, you may need to unfreeze a service manually from the command line if you stopped the WEBGUI service or you cannot access the console.

Procedure

  • Follow these steps to freeze a service from the cluster management console:
    1. From the cluster management console Dashboard, select System & Services > EGO Services > Services

      The Services page displays.

    2. In your consumer tree, navigate to where the service you want to unfreeze is registered, or click the cluster name to see a list of all registered services.
    3. Select the service that you want to unfreeze, click Actions and select Unfreeze.
    4. Click OK to confirm that you want to unfreeze the service.
  • Follow these steps to unfreeze a service manually from the command line:
    1. Run egosh service view to see the current status of your services.

      If the service you want to unfreeze is in the FROZEN state, proceed to the next step.

    2. Run egosh service unfreeze service_name where service_name is the name of the service you want to unfreeze.

Results

Once a service is unfrozen, its next state depends on the number of service instances in the RUN and HOLD states.
  • If the number of service instances in RUN and HOLD states is higher than or equal to the value of the MinInstances parameter configured in the service profile, the service is placed in STARTED state.
  • If the number of service instances in RUN and HOLD states is less than the value of the MinInstances parameter, the service is placed in ALLOCATING state. It is then free to request more resources from EGO if service instances are still waiting to start.
