早些时候我在执行Virtual Connect的固件升级时遇到错误" Virtual Connect Manager的域状态不正确，更新将不会继续"，其中VC模块之一出现硬件错误，之后更换了相应的VC模块。
现在，更换后，新的VC模块的固件版本为4.62，而现有的VC模块的固件版本为4.61，这就是为什么它们都无法同步的原因。
在这种情况下，非常期望两个互连模块之间的同步将失败，并显示为"不兼容"。

因此，在本文中，我将分享一些步骤来修复两个VC互连模块都使用不同固件版本运行的情况，并修复" Virtual Connect Manager的域状态不正确，更新不会继续"的错误消息。

现在，尝试使用vcsu-1.12升级VC固件时，出现以下错误

ERROR: The signature verification of specified package has failed

为了解决这个问题，我下载了" vcsu-1.14"，它解决了上述问题，但原来的问题即Virtual Connect Manager的域状态不正确。
更新将继续存在，其中在尝试升级/降级VC时输出低于输出固件

Stacking Connection: Failed
Stacking Redundancy: No Redundancy
The domain status of Virtual Connect Manager is not OK Update will not continue.

或者

-------------------------------------------------------------------
ERROR: Fatal error. One or more modules is preventing VCSU from continuing.
Correct the conditions listed above and retry.
---------------------------------------------------------------------

如何解决" Virtual Connect Manager的域状态不正确，更新不会继续"的问题？

要解决此错误" Virtual Connect Manager的域状态不正确，更新将无法继续"，我们必须使用vcsu中的" health"选项而不是" version"来执行固件更新。

重要的提示：

我们必须将固件更新到两个互连模块之间更高的版本，即在我的情况下，我的一个互连模块在4.61上而另一个在4.62上，因此我将两个模块的固件更新到4.62. 如果我们尝试对任何其他版本(例如4.63或者4.45)执行固件更新，则固件更新将再次失败。

让我们从固件更新开始。
我们可以根据环境从Linux或者Windows的HPE Official Page下载VCSU。

提示：

无需关闭机箱中刀片的电源，因为这是固件更新，而不是降级。
如果计划进行固件降级，则必须关闭所有刀片的电源并删除域

安装VCSU rpm，因为我是从Linux环境运行的，所以我使用了rpm文件

# rpm -Uvh vcsu-1.14.0.i686.rpm 
warning: vcsu-1.14.0.i686.rpm: Header V3 RSA/SHA256 Signature, key ID 61f75573: NOKEY

从官方HPE页面获取VC固件bin文件以执行固件更新

从终端执行vcsu
