Do Not Attempt to Remove Busy Virtual Devices

Before removing virtual devices with the hpvmmodify command, make sure that the guest operating system is no longer directing I/O to the device. Unmount the device if it is mounted. If you attempt to remove a device that has I/O in progress, the hpvmmodify command incorrectly removes the device from the guest configuration file. The hpvmstatus command no longer displays the device, and the hpvmmodify command does not retry the device removal, but the guest operating system sees the device as available. To remove the device, restart the guest.
