批量修改vsphere共享存儲多路徑選擇策略

傳統方式修改存儲的多路徑選擇策略

首先說一下傳統web界面操做方式：

vSphere 6.5.0.23000

能夠看到至少須要點擊6次才能修改完成一個修改。在生產環境中通常會掛載不少FC存儲，這時候就須要一個批量快捷的方式來修改。

使用Powercli批量修改存儲多路徑選擇策略

• 使用 get-vmhost | get-scsilun 能夠看到當前全部主機鏈接的FC多路徑策略。

PS D:\> get-vmhost | get-scsilun

能夠看到不少都是"Fixed(固定)"狀態，通常來講建議改成"RoundRobin(循環)"

• 配合使用Set-ScsiLun -MultipathPolicy RoundRobin能夠批量將多路徑策略改成"RoundRobin(循環)"模式

PS D:\> Get-Cluster -Name Cloud_Production_Cluster | Get-VMHost | Get-ScsiLun| Set-ScsiLun -MultipathPolicy RoundRobin

參數說明：

• Get-Cluster -Name Cloud_Production_Cluster 指定集羣
• Get-VMHost 全部主機
• Get-ScsiLun 獲得LUN信息
• Set-ScsiLun -MultipathPolicy 設置MultipathPolicy 策略爲RoundRobin OR Fixed
