VMWare vSphere vCenter Log4j补丁

VMWare vSphere ESXi 7 没有受到Apache Log4j 的影响,但是vCenter 确受到了影响. 我们的一台vCenter 服务器就因此被攻击两次.

解决方案:

VMWare vCenter目前还没有发布新的版本来解决这个问题,只提供了一个python脚本来临时解决这个问题.

2 通过SSH登录ESXi Host

3 通过如下的命令查看ESXi Host上的所有disk名称

esxcli storage core device list

4 通过如下的命令查看单独的disk 的smart 信息

esxcli storage core device smart get -d=deviceID
