From the xe help host-shutdown and xe help host-disable
"If no parameters to select hosts are given, the operation will be performed on all hosts."
I have a single host pool, so I can't test.
Are you using EXT or LVM?

Let me ping @Team-XAPI-Network for the xe command to remove this parameter, and ping @bastien-nollet to see how we could get rid of this limitation that blocks removing bogus devices.
