Storage Pools on windows failover cluster : pool assignment cluster / nodes?

Dear,

Scope:

Windows 2019 : two node failover cluster ; no shared disks (SQL AOAG purpose).

We have already enabled this on the cluster :

Get-StorageSubSystem | Where AutomaticClusteringEnabled -eq $true | Set-StorageSubSystem -AutomaticClusteringEnabled $false

 

Observations:

Storage pools created before clustering feature was enabled : they are assigned to the node.

Storage pools created after clustering software is installed : they are assigned to the cluster (using GUI)

 

Q: Can you transfer Storage pool ownership from cluster <-> nodes ?

Q: How can you influence this using GUI / PowerShell?

 

Assignment using GUI (see Available to) :

Clusterpool (see available to)

 

Assignment using PowerShell

$storagePool = New-StoragePool -FriendlyName $storagePoolName -StorageSubSystemUniqueId $storageSubSystem.uniqueID -PhysicalDisks (Get-PhysicalDisk -StorageSubSystem $storageSubSystem -CanPool $true)

Nodepool (see available to)

I don't understand why it assigns storage pool to the nodes this time and not cluster? I don't see it in the command (value for $storageSubSystem was : Clustered Windows Storage on LAB-SQL150AO)

 

 

 

Thanks,

 

Tim
