Cloud Hard Disks That Are Migrated to FusionSphere OpenStack Using Rainbow Cannot Be Deleted from ServiceCenter
【Product�? ServiceCenter 【Version�? 3.0.8 【Fault Type�? Resource management fault 【Symptom�? The icon for deleting such a cloud hard disk is dimmed so that the cloud disk cannot be deleted. 【Fault Locating�? Possible cause: The cloud hard disk is created using an image, but the cloud hard disk is not mounted to a VM. As a result, the cloud hard disk fails to be managed by ServiceCenter. Check method: Step 1 Use PuTTY and the floating IP address to log in to the ServiceCenter server as user galaxmanager. The default password is Huawei@CLOUD8. Check the arcontrol.log file. The value of the bootable field of the cloud hard disk is true. ----End Conclusion: When managing a cloud hard disk, ServiceCenter determines whether the cloud hard disk is a system disk. If the value of the bootable field of the cloud hard disk is true, the cloud hard disk is considered as a system disk. When a system disk is managed by ServiceCenter, the service instance of the cloud host to which the disk is mounted is inserted into the database. However, the cloud hard disk experiencing the exception is not mounted to the cloud host. As a result, the cloud hard disk cannot be managed by ServiceCenter successfully. 【Troubleshooting Procedure�? Step 1 Log in to ServiceCenter as a VDC administrator. Step 2 Go to the Cloud Hard Disk page and check the ID of the cloud hard disk that cannot be deleted. Step 3 Use PuTTY to log in to the cascading FusionSphere OpenStack controller node as user fsp. Step 4 Run the following command to switch to user root: su - root Step 5 Run the following command to import environment variables: source set_env Step 6 Run the following command to delete a cloud hard disk: Cinder delete Cloud hard disk ID ----End

What Are the Precautions for Expanding the Capacity of the Cloud Hard Disk When the Capacity of a ServiceCenter Cloud Host or Dedicated Server Cloud Hard Disk Is Insufficient
【Product�? ManageOne ServiceCenter 【Version�? 3.0 【Question�? What are the precautions for expanding the capacity of the cloud hard disk when the capacity of a ServiceCenter cloud host or dedicated server cloud hard disk is insufficient? 【Answer�? The capacity of a cloud hard disk that has been mounted to a cloud host or a dedicated server cannot be expanded. If the AZ type is FusionCompute, the capacities of cloud hard disks whose capacity is less than 4 GB cannot be expanded. The capacities of cloud hard disks that have snapshots created can be successfully expanded only when the storage type is FusionStorage. If the cloud hard disk capacity fails to be expanded, reset the cloud hard disk status. ----End
