提醒：由于新代码级别中增强了安全强化，因此删除云单元现在需要启用安全用户凭据和安全授权。请参阅本文的 “其他信息” 部分。
sysadmin@datadomain# cloud unit del ecs-temp-ct This command requires authorization by a user having a 'security' role. Please present credentials for such a user below. Username: secofficer Password: Please enter sysadmin password: This command irrevocably destroys all data in the cloud unit "ecs-temp-ct". Are you sure? (yes|no) [no]: yes ok, proceeding. Destroying cloud unit "ecs-temp-ct" Cloud unit 'ecs-temp-ct' deleted. The data in the cloud will be deleted asynchronously on the filesystem startup. - 文件系统重新启动后，云单元状态将更改为“Delete-Pending”。完全卸下设备可能需要一段时间。

Additional Information
故障处理
安全专员
sysadmin@datadomain# cloud unit del ecs-temp-ct
**** Security officer authorizations must be enabled.- 使用以下命令验证安全用户是否存在：
user show list。 - 如果不存在安全用户， 请创建一个。
- 使用安全凭据登录到重复会话，并使用命令启用安全授权
authorization policy set security-officer enabled。 - 使用 sysadmin 凭据返回到 DD CLI，并继续执行删除过程。
如果删除仍然失败，并且显示
"This command is not allowed with current security configuration," 以下一项或多项可能适用：
- 安全专员帐户已在 24 小时的工作时间内创建（如果包括周末，这可能意味着 5 天）
- 系统时间已在 24 个工作小时内更改
- 警报通知列表在 24 个工作小时内更改
如果是这种情况，您必须等到此期限结束。这是没有办法的。
删除挂起
完全删除云单元可能需要一段时间，最长可能需要一天或更长时间。如果云单元长时间处于 “Delete-pending” 状态，可能是数据被错误地删除了。有关解决方法，请参阅 此文章 。Affected Products
