批量修改vsphere共享存储多路径选择策略

2021-01-01 22:03:29 作者：互联网

传统方式修改存储的多路径选择策略

首先说一下传统web界面操作方式：

可以看到至少需要6次才能修改完成一个。在生产环境中一般会挂载很多FC存储，这时候就需要一个批量快捷的方式来修改。

使用Powercli批量修改存储多路径选择策略

使用 get-vmhost | get-scsilun 可以看到当前所有主机连接的FC多路径策略。

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

可以看到很多都是"Fixed(固定)"状态，一般来说建议改为"RoundRobin(循环)"

配合使用Set-ScsiLun -MultipathPolicy RoundRobin可以批量将多路径策略改为"RoundRobin(循环)"模式

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

naa.600... /vmfs/devices/disks/naa.600... disk             3,071.935 RoundRobin

naa.650... /vmfs/devices/disks/naa.650... disk             2,234.500 RoundRobin
naa.600... /vmfs/devices/disks/naa.600... disk             3,071.935 RoundRobin
naa.500... /vmfs/devices/disks/naa.500... disk             1,117.813 RoundRobin
naa.500... /vmfs/devices/disks/naa.500... disk             1,117.813 RoundRobin
naa.500... /vmfs/devices/disks/naa.500... disk             1,117.813 RoundRobin
naa.500... /vmfs/devices/disks/naa.500... disk             1,117.813 RoundRobin
mpx.vmh... /vmfs/devices/disks/mpx.vmh... disk                 0.000 RoundRobin
......

参数说明：

Get-Cluster -Name Cloud_Production_Cluster 指定集群
Get-VMHost 所有主机
Get-ScsiLun 得到LUN信息
Set-ScsiLun -MultipathPolicy 设置为MultipathPolicy 为RoundRobin OR Fixed模式
