问题描述

文件：https://drive.google.com/file/d/10GAlcA9PI-mFHUmACvC5CPbzjl3QLrwJ/view?usp=sharing

$data = import-csv .\vdisk.csv |where 'raw lun id' -NotLike ''|group-object -Property VM -ashashtable

我从 rvtools 中提取了 vdisk 并尝试按 VM 名称对共享 RDM 进行分组，代码的输出是：

Name                           Value
----                           -----
MGTMKS1112M                    {@{VM=MGTMKS1112M; Powerstate=poweredOff; Template=False; disk=Hard disk 7; Capacity MB=150; Raw=True; disk Mode=independent_persistent; Thin=; Eagerly Scrub=; Split=; Wri...

我想要类似下面的 ashashtable 或分组对象的输出。因为两个节点共享相同的原始 lun id。如果这种方法行不通。任何替代方法？请指教。


Name                      Value
----                      -----
MGTMKS1112M,MGTMKS1111M   {@{VM=MGTMKS1112M; Powerstate=poweredOff; Template=False; disk=Hard disk 7; Capacity MB=150; Raw=True; disk Mode=independent_persistent; Thin=; Eagerly Scrub=; Split=; Wri...

解决方法

您可以向 Group-Object 提供自定义属性，以便在其中进行分组

$data = import-csv .\vDisk.csv |where 'raw lun id' -NotLike ''
$data | Group-Object -Property { $sub = $_.vm.substring(0,9); ($data.vm -match $sub |  Select-Object -Unique | Sort-Object) -join ","} -ashashtable

输出类似这样的东西

    Name                     Value
----                     -----
MGTMKS1111M,MGTMKS1112M {@{VM=MGTMKS1111M; Powerstate=poweredOff; Template=False; Disk=Hard disk 11; Capacity MB=150; Raw=True; Disk Mode=independent_persistent; Thin=; Eagerly Scrub=; Split=; Write Through=; Level=normal; Shares=1,000; Reservation=0; L...
