Show local disks and format them? (Powercli)

[MattG]

I am trying to figure out how to find unformatted local volumes that I can format as VMFS.

I can gather all volumes via:

Get-SCSILun -VMhost $vmhost

And see which ones are attached to local storage controller,  but cant figure out how to only include unformatted volumes?

Thanks in advance LucD :)

Have a look at my LUN report – datastore, RDM and node visibility post.
That shows which LUNs are available.

Is there anyway to execute this without the requirement for this:

Add-Type -Language CsharpVersion3 -TypeDefinition $LunInfoDef

I cant load the necessary components to get this to work.

Thanks

Did you try changing CsharpVersion3 with CSharp?

Is there a way to skip formatting a VMFS on the leftover disk space on the disk containing the ESX OS Data?

Thanks!

Not that I know of.
But in ESXi 8 the creation of that VMFS partition depends on the size of the disk.
See ESXi System Storage Overview

You could experiment with the systemMediaSize = max parameter

Thx!   I saw the  systemMediaSize = max parameter but it does feel more experimental and would need to be tested.   My alt is to just exclude disks under a certain size though is not ideal as we could end up excluding disks they we want.

Afaik, that parameter is only for the system disk.
