對 vSAN 使用 Esxcli 命令

使用 Esxcli 命令可取得 vSAN 的相關資訊，以及對您的 vSAN 環境進行疑難排解。

可用命令如下：

命令	描述
esxcli vsan network list	確認哪些 VMkernel 介面卡可用於 vSAN 通訊。
esxcli vsan storage list	列出 vSAN 宣告的儲存區磁碟。
esxcli vsan cluster get	取得 vSAN 叢集資訊。
esxcli vsan health	取得 vSAN 叢集健全狀況狀態。
esxcli vsan debug	取得 vSAN 叢集偵錯資訊。

esxcli vsan debug 命令可協助您對 vSAN 叢集進行偵錯和疑難排解，特別是當 vCenter Server 無法使用時。

用法：esxcli vsan debug {cmd} [cmd options]

偵錯命令：

命令	描述
esxcli vsan debug disk	偵錯 vSAN 實體磁碟。
esxcli vsan debug object	偵錯 vSAN 物件。
esxcli vsan debug resync	偵錯 vSAN 重新同步物件。
esxcli vsan debug controller	偵錯 vSAN 磁碟控制器。
esxcli vsan debug limit	偵錯 vSAN 限制。
esxcli vsan debug vmdk	偵錯 vSAN VMDK。
