Vmware datatore delet and remove from storage question

I have created a lun for testing from storage and I finished my VM testing. Now I deleted the volumes from, OS and removed it from VM. I want to know the proper way to remove the LUN. Can I now go ahead and delete the datastore, and then delete the LUN?

the proper way to remove the LUN from an ESXi host

1. is the mask the LUN first.

see here

2. then re-scan storage.

3. remove the LUN from SAN. (using SAN GUI or Tools).

Yep...as long as no needed VMs or data is on it. Just rt-click on it and select Delete (NOTE: this operation wipes all data off it). Once deleted from your Host/vCenter, you can then remove the LUN on your SAN if you want.

if you continue todo that you will expose a bug in ESXi, which hangs your server for hours!

mask first, then remove! (proper way!)

1. Power off the VMs from the datastore which you are planning to remove.
2.remove from inventory,
3.Delete the datastore and remove the lun from the storage side (SAN GUI tool) , unmask the lun.
4.Initiate a new scan to get update all esxi that the luns are removed.
5.try to add a new datastore , you shouldnt see any raw lun in ready mode to configure.
