When you need the host to access the masked storage device, unmask the paths to the device.


Unmask a path to the storage device by running the esxcli corestorage claiming unclaim command.

Run this command for each path to the storage device.

For example:

esxcli corestorage claiming unclaim -t location -A vmhba0 -C 0 -T 0 -L 149


Load path claiming rules into the VMkernel by running the esxcli corestorage claimrule load command.


Run the path claiming rules by entering the esxcli corestorage claimrule run.

Your host can now access the previously masked storage device.
