What Should I Do If I Cannot Create an Application Instance on a VM?

Symptom

When a component is deployed on a VM, an instance fails to be created.

Solution

1. Log in to ServiceStage.
2. Use either of the following methods to go to the Instance List page.
   • On the Application Management page, click the application to which the component belongs, and click the target component in Component List. In the left navigation pane, choose Instance List.
   • On the Component Management page, click the target component. In the left navigation pane, choose Instance List.

3. In the instance list, click next to the target instance.
4. On the Events tab page, click View Details of a failure event to view its cause.
5. View the running logs of an instance on the Logs tab page. If an instance is abnormal, locate the fault.

   Remarks:

   • Instance directories on the ECS host:

     Directory for storing the software package: /opt/ssa/packages/${instanceName}/${instanceVersion}/${instanceId}/

     Instance running directory: /opt/application/${instanceName}/${instanceVersion}/${instanceId}/

     Instance running logs: /var/log/application/${instanceName}/${instanceVersion}/${instanceId}/

     Instance deployment logs: /var/log/servicestage-agent/${instanceName}/${instanceVersion}/${instanceId}/
