Right click on the datastore object and choose Delete, right? Wrong.

    So what is happening when I just right click and delete a datastore? I don’t notice any adverse effects to the environment when doing this, nor do I see anything in the various logs.

    I am using the LUN removal checklist now, but I’m just curious as to what the Right Click->Delete option on a datastore is there for, if one shouldn’t use it. If removing a datastore in this way is bad practice, then it seems like VMware is encouraging bad practices just by having this option present.

    I just did the same mistake.
    the adverse effects when removing (unmapping) a lun from an unproperly detatched datastore, are that you get path errors and time-outs on each hosts. if you do a rescan a that moment, the managment interface may get lost and will not respond. (but the vm still continue to run)
    The only thing that works is a host hard reboot.
