傳統方式修改儲存的多路徑選擇策略
首先說一下傳統web介面操作方式：
可以看到至少需要6次才能修改完成一個。在生產環境中一般會掛載很多FC儲存，這時候就需要一個批量快捷的方式來修改。
使用Powercli批量修改儲存多路徑選擇策略
- 使用
get-vmhost | get-scsilun可以看到當前所有主機連線的FC多路徑策略。
PS D:\> get-vmhost | get-scsilun
CanonicalN ConsoleDeviceName LunType CapacityGB MultipathPolicy

可以看到很多都是"Fixed(固定)"狀態，一般來說建議改為"RoundRobin(迴圈)"
- 配合使用
Set-ScsiLun -MultipathPolicy RoundRobin可以批量將多路徑策略改為"RoundRobin(迴圈)"模式
PS D:\> Get-Cluster -Name Cloud_Production_Cluster | Get-VMHost | Get-ScsiLun| Set-ScsiLun -MultipathPolicy RoundRobin

引數說明：
- Get-Cluster -Name Cloud_Production_Cluster 指定叢集
- Get-VMHost 所有主機
- Get-ScsiLun 得到LUN資訊
- Set-ScsiLun -MultipathPolicy 設定為MultipathPolicy 為RoundRobin OR Fixed模式
