How to properly remove vSphere datastores

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

Following are two good VMware articles outlining the correct procedure for removing datastores in a vSphere environment:




  1. Hi- This post made it to the VMware Global Alliances weekly network news round up.

    Thank you for your great content!

    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.
