If you plan to remove a datastore from a host, you need to remove the coredump files before removing the datastore.

To remove a coredump file from a datastore presented to a cluster or host.

List coredump files:

/vmfs/volumes/500b1009-42f40af0-2511-d8d385e35403 # esxcli system coredump file list
Path                                                                                                               Active  Configured       Size

Remove my file:

esxcli system coredump file remove -f fullpathofcoredumpfile

/vmfs/volumes/500b1009-42f40af0-2511-d8d385e35403 # esxcli system coredump file remove -f /vmfs/volumes/500b1009-42f40af0-251

If your file is active and locked, use -F (–force parameter)

You may need to reboot your host after such procedure.
