For example, removing a VM guest would tell the SAN that the guest had been removed, and if the data store had been thinly provisioned from the SAN, it’d clean up Not so much.
For those machines also we are able migrate disk by disk and few disks get success. This causes a good speed up with regards to moving machines around. When we first observed this issue, we didn’t realize the issue was between SANs, we just thought the issue was random.
Our VM hosts had storage allocated from 2 different SANs at the time, and our naming convention was a little off, so identifying quickly that the data store was on a Fast forward to nine months ago, and we had an issue where we discovered one of our SANs had become over saturated, and needed space and load removed from it.

Storage Vmotion Fails With Error Timed Out Waiting For Migration Data Shutting down some guests and shuffling them around got us through the pinch, but left me wondering. I ran into this & discovered that it occurs when an existing vmdk having the same name as the svmotion source vmdk exists on the target datastore. We put it down to the load and space issues on the SAN and went with the outage.
Intra-SAN migrations would hit 32% and time out. So the solution was to disable VAAI on the host, do the vMotion, and then re-enable it if you still want to use it.
