Use a disk's unique id with the xDisk resource? about storagedsc HOT 3 CLOSED

Just wanted to note that I was able to map NAA IDs to Windows disk numbers in Chef. I used Chef's powershell_out() function to execute Powershell code inside a Chef recipe, and used the output string with some logic to determine the disk number supplied to the xDisk DSC resource.

In that way, I was able to completely and reliably automate the LUN/disk configuration process using DSC with Chef - awesome! Since my original issue is resolved with that workaround, I don't mind if this issue is closed.

@detailedschematic, if possible, could you kindly share with us your Chef/Powershell code so we can see the full solution?

Sorry for the delay. I've pasted a snippet from my Chef recipe below.

A here-doc string contains powershell code:
naaid_to_disknum = <<-code $disk = Get-Disk -UniqueId #{naaid}; return $disk.number code

We call that powershell code in Chef using powershell_out() inside a dsc_resource resource. We use lazy attribute evaluation to delay until the execution phase of convergence:
dsc_resource "xClusterDisk" do resource :xClusterDisk property :Ensure, 'Present' property :Label, label property :Number, lazy { powershell_out(naaid_to_disknum).stdout.chop.to_s } end
