测试期间直接删除了composer服务器，导致link clone生成的replica-xxx命令的副本母机无法删除，需要先解除保护后才能从VCSA中。

　　登录composer服务器，停用掉view composer服务，接着cmd先cd到C:\Program Files (x86)\VMware\VMware View Composer目录下，执行以下命令：

SviConfig -operation=UnprotectEntity -VcUrl=https://VC地址/sdk -DsnName=数据库名 -DbUsername=sa -DbPassword=SA密码 -VcUsername=Administrator@vsphere.local -VcPassword=VC密码 -InventoryPath="/Datacenter/vm/VMwareViewComposerReplicaFolder/replica-96553915-fd20-4fca-9c8c-be3bc9d892e2" -Recursive=true

　　执行过程中遇到了错误的话，请参考以下：

ExitStatus:
  0  - operation ends successfully.
  1  - The supplied DSN name can not be found.
  2  - The supplied credentials are invalid.
  3  - Unsupported driver for the provided database.
  4  - Unexpected problem arisen.
  9  - invalid URL.
  10 - VC can not be accessed.
  11 - entity is not found.
  12 - unknown entity type.
  13 - release failed.
  15 - Other application is using required resources. Stop it and retry
       the operation.
  18 - Unable to connect to database server.
  34 - invalid VC certificate.

　　可算是能删掉了：
