Microsoft Virtualization Discussions
I had the customer run the power shell script for space reclaim on the LUNs. When he attempted to run, he go the following failure message.
S & H are 2 LUNS which failed with message, E is another LUN and that worked.
I had him run the Get-NaHostDisk command and it returned the following. The three highlighted disks are the ones he is unable to reclaim space on. Not sure what my next step should be.
Could you also try using Nc instead of Na ( ("Na" = 7-mode, "Nc" = clustered), as this is an cDOT Luns.
Even though 'Na' also works but you can give it a try:
I would check two other things as well.
1. Is this LUN a cluster resource? If so, you may need to run the command from the Windows node that owns the resource.
2. Ensure that "space-allocation" is enabled on the LUN in ONTAP. If it isn't, then you can't reclaim space from it.
Let us know if that helps.
Came across few threads not exactly same issue but may be helpful: (Also try updating the PSTK kit to latest release)
