I have available 8 x 2TB HDDs and 4 x 400GB SSD's which I want to create a Tiered Storage based Storage Spaces volume with. I want to use 10GB of space for the Quorum volume later. I'm missing something, here's what I'm doing.
Here's my physical disks:
PS C:\Users\administrator> Get-PhysicalDisk FriendlyName CanPool OperationalStatus HealthStatus Usage Size ------------ ------- ----------------- ------------ ----- ---- PhysicalDisk3 True OK Healthy Auto-Select 372.61 GB PhysicalDisk6 True OK Healthy Auto-Select 372.61 GB PhysicalDisk1 True OK Healthy Auto-Select 1.82 TB PhysicalDisk4 True OK Healthy Auto-Select 372.61 GB PhysicalDisk8 True OK Healthy Auto-Select 1.82 TB PhysicalDisk5 True OK Healthy Auto-Select 372.61 GB PhysicalDisk12 True OK Healthy Auto-Select 1.82 TB PhysicalDisk2 True OK Healthy Auto-Select 1.82 TB PhysicalDisk9 True OK Healthy Auto-Select 1.82 TB PhysicalDisk11 True OK Healthy Auto-Select 1.82 TB PhysicalDisk10 True OK Healthy Auto-Select 1.82 TB PhysicalDisk7 True OK Healthy Auto-Select 1.82 TB
I assign the available physical disks to the array variable $PhysicalDisks
$pooldisks = Get-PhysicalDisk | ? {$_.CanPool eq $true }
Then I create a new storage pool using $pooldisks.
New-StoragePool -StorageSubSystemFriendlyName *Spaces* -FriendlyName TieredPool1 -PhysicalDisks $pooldisks
Then I assign them to SSD and HDD tiers:
$tier_hdd = New-StorageTier -StoragePoolFriendlyName TieredPool1 -FriendlyName HDD_TIER -MediaType HDD $tier_ssd = New-StorageTier -StoragePoolFriendlyName TieredPool1 -FriendlyName SSD_TIER -MediaType SSD
And I get stuck trying to create the Virtual Disk:
New-VirtualDisk -FriendlyName VirtualDisk1 -StoragePoolFriendlyName TieredPool1 -NumberOfColumns 4 -OtherUsageDescription "8 x 2TB HDD and 4 x 400GB SSD" -ProvisioningType Fixed -ResiliencySettingName Mirror -StorageTiers $tier_ssd, $tier_hdd -StorageTierSizes 800GB, 8000GB -WriteCacheSize 5GB
The error message I receive is:
New-VirtualDisk : There are not enough eligible physical disks in the storage pool to create the specified virtual disk configuration.
At line:1 char:1
+ New-VirtualDisk -FriendlyName VirtualDisk1 -StoragePoolFriendlyName TieredPool1 ...
+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+ CategoryInfo : InvalidOperation: (StorageWMI:ROOT/Microsoft/...SFT_StoragePool) [New-VirtualDisk], CimException
+ FullyQualifiedErrorId : StorageWMI 48004,New-VirtualDisk
The reason I am trying to do this manually and not via the GUI, is because I need to assign 4 columns to the Storage Space, and the GUI defaults to 2. Any help is appreciated.
