unmap will work with freeing space after VMDKs have been moved/deleted but to free space from within the VMDK files you need to run tools within the VM Guest OS itself to write zeros. |

Fernando, do you mean from guest OS? In wich case specify OS and 3PAR SW version. |

Here is the procedure that I follow (hopefully no one is still running 5.1) sDelete Inside of each Windows guest run sdelete.exe against each drive Sdelete.exe -s -z <drvltr>: Manually Run UNMAP VMware 5.1: 1. SSH into the esxi host 2. Change into the /vmfs/volumes/<datastore> 3. Run UNMAP as follows: vmkfstools -y 99 To run this against ALL of the volumes, assuming the volume name contains 3PAR, issue the following command: for i in `ls /vmfs/volumes |grep 3PAR`; do cd /vmfs/volumes/$i && vmkfstools -y 90; done This will run one volume at a time so it will be slow but is the best way to minimize I/O impact. VMware 5.5/6.x: 1. SSH into the esxi host 2. Change to /vmfs/volumes/ 3. Run ls to get a listing of the datastores that are present 4. Run UNMAP as follows: esxcli storage vmfs unmap -l <volume_label> You can also run this against the uuid using the following command: esxcli storage vmfs unmap -u <volume_uuid> On the 3PAR run compactcpg |
