Deleting a cloud LSU

Use the following steps carefully to remove an MSDP cloud LSU.

If a cloud LSU is associated with an MVG volume, delete the MVG volume first before deleting the cloud LSU. Run the cacontrol --dataselection list command to check if the cloud LSU is associated with an MVG volume. If there is an association, the command output displays the cloud LSU description as UsedByVLSU=<mvg-server>:<mvg-volume>. For example, in the following output, cloud volume demohost-cloud is associated with MVG volume mvg-cloud of MVG server mvgdemo-host1.mvgdemo.com.

cacontrol --dataselection list

    {
        "dsid": 3,
        "type": 9,
        "name": "demohost-cloud",
        "description": "UsedByVLSU=mvgdemo-host1.mvgdemo.com:mvg-cloud;"
    }
]
