what i wrong ?

It looks like you have tried to pass through a device that belongs in an IOMMU group with other devices.

 

The rule for a passthrough is that the device you are passing through must be in its own IOMMU group, or you must pass through all devices in the same IOMMU group to the same VM.

 

It's usual for onboard devices (WiFi, Ethernet, Some SATA, OnBoard Audio) to be grouped together. You can try to get around this using Bios ACS settings and/o ACS override settings in unRaid, but it's often difficult .
