HPE MSA 2060 AND Using unmap command from Windows Server

KumarRasiah — Fri, 08 Sep 2023 12:35:32 GMT

Hi There

We have couple of HPE MSA 2060 iSCSI which is being used as a backup repository from Windows Server as ReFS Volumes.

Is there a way to clear up space on the MSA from Windows using the unmap commands. Any help would be greatly appreciated.

KInd Regards

Kumar

@KumarRasiah
Looking around it seems that Microsoft does not recommend using ReFS when TRIM/UNMAP are required. https://learn.microsoft.com/en-us/windows-server/storage/refs/refs-overview

Everything I found indicated that UNMAP commands would not work on ReFS volumes.
