Why Is Failed Displayed for a BMS Application Task But the BMS List Shows the Obtained BMS?

Symptom

After I apply for a BMS that requires an EIP on the management console, the BMS application request was successfully processed but binding the EIP failed due to insufficient EIPs. In this case, Failed was displayed for the task in the Task Status area. However, the requested BMS was displayed in the BMS list.

Root Cause

• The BMS list shows the details about obtained BMSs.
• The Task Status area shows the processing status of the BMS application task, including statuses of sub-tasks, such as preparing for the BMS resource and binding an EIP. Only when all subtasks have succeeded, the task status becomes Succeeded. Otherwise, the task status is Failed.

If the BMS is successfully provisioned but EIP binding fails, Failed is displayed for the task. The provisioned BMS is temporarily displayed in the BMS list. After the system rolls back the failed task, the BMS is removed from the list.
