Hello,
I am using the below two functions that I found elsewhere on the forums for removing a datastore. I run the Unmount-Datastore followed by the Detach-Datastore functions.
However when I run them, the datastore still shows in vCenter as a red circle with line (inactive and inaccessible). The only way I've found to eliminate it is to reboot each host. This seems akin to the All Paths Down (APD) issue, but I thought I am cleanly removing it, as I run these before doing anything on the LUN/SAN side of this.
Can anyone explain how to get these datastores to cleanly disappear on removal?
Thanks!
