验证服务状态，服务可能会显示为“up and running”：

vcp-cli bg status（检查 VPA 上的备份网关服务状态）
vcp-cli srv status（检查 VPA 上的 SRV/Cell 服务状态）
systemctl status vcp-manager.service（检查 VPA 上的 VCP-MANAGER 服务状态）

提醒：已在 VCP 19.4 上发现问题

目前未知

1.打开与 VPA 虚拟机的 SSH 连接。

2.重新启动 vcp-manager 服务：
systemctl restart  vcp-manager.service

3.验证服务是否正在运行：
systemctl status vcp-manager.service

4.重新启动 srv-cell 服务：
vcp-cli srv stop --password <MASTERPASS> <Cell-Instance-name>
vcp-cli srv start --password <MASTERPASS> <Cell-Instance-name>

5.验证服务是否正在运行：
vcp-cli srv status

6.重新启动 BG 服务：
vcp-cli bg stop --password <MASTERPASS>  <BG-Instance-name>
vcp-cli bg stop --password <MASTERPASS>  <BG-Instance-name>

7.验证服务是否正在运行：
vcp-cli bg status

8.重新打开 DPE 提供程序 UI，确认“Data Protection”选项卡填充正确的信息，并且备份网关报告正确的版本。
