电源外壳。使用正确的磁盘创建2个存储空间池

我尝试创建一个脚本,创建2个存储空间池,每个池有4个磁盘。但是,由于缓存要求,我需要将具有LUN0-3的磁盘用于pool1,将磁盘用LUN4-7用于pool2。我使用以下脚本创建了2个池,但每次运行它都会创建来自不同磁盘的池(参见屏幕截图):

$disks = Get-PhysicalDisk -CanPool $true | select -first ((Get-PhysicalDisk -CanPool $true).count/2)
New-StoragePool -FriendlyName "DataPool" -StorageSubsystemFriendlyName "Windows Storage*" -PhysicalDisks $disks | New-VirtualDisk -FriendlyName "DataDisk" -UseMaximumSize -NumberOfColumns $disks.Count -ResiliencySettingName "Simple" -ProvisioningType Fixed | Initialize-Disk -Confirm:$False -PassThru | New-Partition -DriveLetter S –UseMaximumSize | Format-Volume -FileSystem NTFS -NewFileSystemLabel "SQLDATA" -AllocationUnitSize 65536 -Confirm:$false            

$disks2 = Get-PhysicalDisk -CanPool $true
New-StoragePool -FriendlyName "LogsPool" -StorageSubsystemFriendlyName "Windows Storage*" -PhysicalDisks $disks2 | New-VirtualDisk -FriendlyName "LogsDisk" -UseMaximumSize -NumberOfColumns $disks.Count -ResiliencySettingName "Simple" -ProvisioningType Fixed | Initialize-Disk -Confirm:$False -PassThru | New-Partition -DriveLetter L –UseMaximumSize | Format-Volume -FileSystem NTFS -NewFileSystemLabel "SQLLOGS" -AllocationUnitSize 65536 -Confirm:$false   

我怎样才能让它发挥作用? enter image description here

答案 0 :(得分:4)

您可以通过deviceId对它们进行排序以获取正确的磁盘吗?

$disks = Get-PhysicalDisk -CanPool $true | Sort-Object deviceid | select -first ((Get-PhysicalDisk -CanPool $true).count/2)

或以其他方式使用deviceId显式指定磁盘0-3和4-7

master

尝试这样排序

答案 2 :(得分:0)

有点晚了,但是:我使用驱动器序列号或唯一ID来确保获得正确的驱动器。

这是使用序列号的真实示例。这是从我的日志创建一个奇偶校验空间开始,我总是记录我如何创建存储空间。我在这里省略了不用于存储空间的驱动器:

Get-PhysicalDisk | ft friendlyname,canpool,cannotpoolreason,size,uniqueid,SerialNumber,Usage

friendlyname            canpool CannotPoolReason               size uniqueid         SerialNumber    Usage
------------            ------- ----------------               ---- --------         ------------    -----
ST33000651AS               True                       3000592982016 5000C5002DFAB4EE 9XK0EC9S        Auto-Select
WDC WD30EFRX-68AX9N0       True                       3000592982016 50014E6EADFAE1EF WD-WMC1T3418930 Auto-Select
WDC WD30EFRX-68AX9N0       True                       3000592982016 50014E6E58A5BD05 WD-WMC1T3536082 Auto-Select

New-StoragePool -FriendlyName Pool-F -StorageSubSystemFriendlyName "Windows Storage*" -LogicalSectorSizeDefault 4096 -PhysicalDisks (Get-PhysicalDisk | ?{"9XK0EC9S;WD-WMC1T3418930;WD-WMC1T3536082".Contains($_.SerialNumber)})
    
FriendlyName OperationalStatus HealthStatus IsPrimordial IsReadOnly    Size AllocatedSize
------------ ----------------- ------------ ------------ ----------    ---- -------------
Pool-F       OK                Healthy      False        False      8.19 TB        768 MB

我本可以使用唯一ID:

New-StoragePool -FriendlyName Pool-F -StorageSubSystemFriendlyName "Windows Storage*" -LogicalSectorSizeDefault 4096 -PhysicalDisks (Get-PhysicalDisk | ?{"5000C5002DFAB4EE;50014E6EADFAE1EF;50014E6E58A5BD05".Contains($_.uniqueid)})

在您的情况下,您也可以使用PhysicalLocation或ObjectID作为选择器...这里列出了当前位置以及实际位置:

Get-PhysicalDisk | ft friendlyname,canpool,cannotpoolreason,size,uniqueid,SerialNumber,PhysicalLocation,Usage

friendlyname            canpool CannotPoolReason               size uniqueid         SerialNumber    PhysicalLocation                                                Usage
------------            ------- ----------------               ---- --------         ------------    ----------------                                                -----
