Restarting SIMs and service instances for an application

You can restart SIMs and their service instances for an application without stopping active workload and losing workload results. For scheduled tasks, SSM stops these tasks for the specified application and hosts, and after tasks results are received, restarts the applications.

Before you begin

You cannot restart service instances enabled in global standby mode; terminate these standby service instances first, by running the egosh globalstandby kill command (see Terminating standby service instances for details).

About this task

You can restart SIM and service instances using either the cluster management console or the soamcontrol service restart command. From the cluster management console, you can restart a SIM and its service instance, for one application at a time, on all hosts for that application. The command line method is slightly more flexible as it provides the option to restart for a specific application or all of them, and on one host or all of them.

Procedure

  • From the cluster management console:
    1. Select Workload > Symphony > Applications.
    2. Select the application name from the list.
    3. Click Restart to display the confirmation dialog.
    4. Optional: Allow the system to wait before restarting services, so that running workload can complete before restarting services. To do this, specify a value, in seconds, in the field on this dialog. Ensure that the value is a whole number greater than zero.
    5. Click OK.
  • From the command line:
    1. Run the soamcontrol service restart command:
      soamcontrol service restart application_name | all [-u user_name] [-x password] [-t timeout] [-r host1[,host2,..]]
