升级完vCenter后还需要升级ESXi，为什么非要升级ESXi呢？主要原因还是支持新的Guest OS和POC验证需要。看上去十分简单的esxi升级却也会遭遇波折，一起看看：
准备好安装所需的介质文件：
VMware-VMvisor-Installer-6.7.0.update03-14320388.x86_64.iso
VMware-ESXi-6.7.0-8169922-depot.zip
开始Troubleshoot过程，爬墙搜索一下发现很多NVME在ESXi 6.7u2/u3下都无法识别了，还有很多是在6.7 GA版下还能识别。于是按照高手做法用旧版nvme vib替换新版的vib。需要在VMware-ESXi-6.7.0-8169922-depot.zip(可以自行网络搜索下载到该文件)中找到以下两个vib并上传到/tmp目录安装：
VMware-ESXi-6.7.0-8169922-depot/vib20/nvme/VMW_bootbank_nvme_1.2.1.34-1vmw.670.0.0.8169922.vib
VMware-ESXi-6.7.0-8169922-depot/vib20/vmware-esx-esxcli-nvme-plugin/VMware_bootbank_vmware-esx-esxcli-nvme-plugin_1.2.0.32-0.0.8169922.vib
[root@vmnode2:~] esxcli software vib list | grep nvme

安装vib后重启ESXi主机，就能看到HP NVME回来了！
整个homeLAB升级工作就这样成功完成了！
