Deleting / Removing a datastore

[ChocolateStout4]

Hi, we are sun-setting a SAN, and therefore removing a bunch a datastores. I've read in an article that we need to do some volume Masking.

Is that really neccessary? We've removed all vms and data from these datastores. These datastores are virtually empty.

Can we just delete these datastores and then un-presenting those LUNs from the SAN?

Thanks.

I never do any volume masking when I remove a lun from a host.  I just remove everything from the datastore, delete the datastore and then un-present those LUNs from the SAN
