I tried to use unmap command for a vmfs datastore but I got the following error:
"Devices backing volume 556c77e1-b49cf970-f474-10604ba82a40 do not support UNMAP"
I read that space allocation should be enabled for the corresponding lun in order to use this command.
I just wanted to know what is the impact of "lun set space_alloc <lun_path> enable" command?
I mean, is it safe to run this command on a production lun when the lun is online and used by many users ?

Even after enabling space allocation I'm still facing:
"Devices backing volume 556c77b8-458abb2e-73f2-10604ba82a40 do not support UNMAP"
The output of "esxcli storage core device vaai status get -d naa.60a9800038303246792b475348684159" command is showing the delete status as unsupported.

Do you have any idea ?

Have you checked this KB? https://kb.netapp.com/app/answers/answer_view/a_id/1001100
It might depend on a few things. I'd make sure you're on 8.2.5P1 (or is P2 out?) and start there. If you can't get it after that let's get a support case open so we can review your system individually. There probably is something simple but I'd have to look at an ASUP to have a better idea.
