As many of you will have experienced, we've been battling with reclaiming zero space on our 3PAR especially where we've been performing storage vMotions / deletion of disks from guests for some time now. As such, we've written the attached powershell to run a 'zeroing' process within our VMware / 3PAR environment which in effect: a) connects with the specified vCenter server b) locates all datastores which match any input parameters (will select all by default) c) creates a new VM guest with a name aligned with the datastore and a random number d) creates 50GB disks (EagerZeroThick) attached to this guest until the required space is filled (to a minimum 'space' level determined at runtime) e) deletes the guest (and disks) returning the space to the 3PAR for re-use I've got this working in serial i.e. one datastore after another which seems to work nicely for us in our environment (100TB useable) Please use ZeroDatastores.ps1 -? for details on how to use Let me know if this is any use to the community. Cheers Steve
