可用命令如下：
| 命令 | 描述 |
|---|---|
| esxcli vsan network list | 确认哪些 VMkernel 适配器可用于 vSAN 通信。 |
| esxcli vsan storage list | 列出由 vSAN 声明的存储磁盘。 |
| esxcli vsan cluster get | 获取 vSAN 群集信息。 |
| esxcli vsan health | 获取 vSAN 群集运行状况。 |
| esxcli vsan debug | 获取 vSAN 群集调试信息。 |
使用 esxcli vsan debug 命令可调试 vSAN 群集并对群集进行故障排除，尤其是 vCenter Server 不可用时。
使用：esxcli vsan debug {cmd} [cmd options]
调试命令：
| 命令 | 描述 |
|---|---|
| esxcli vsan debug disk | 调试 vSAN 物理磁盘。 |
| esxcli vsan debug object | 调试 vSAN 对象。 |
| esxcli vsan debug resync | 调试 vSAN 重新同步对象。 |
| esxcli vsan debug controller | 调试 vSAN 磁盘控制器。 |
| esxcli vsan debug limit | 调试 vSAN 限制。 |
| esxcli vsan debug vmdk | 调试 vSAN VMDK。 |
