Someone said that it is because the kernel option CONFIG_XEN_DEV_EVTCHN should be set as 'y' but not 'm', so I checked my linux kernel configuration, and found it is set as 'y'.

 

I can find /sys/bus/scsi/devices/host0/target0:0:0:0/0:0:0:0/vendor, or /sys/bus/scsi/devices/host0/target0:0:0:0/0:0:0:0/scsi_device/0:0:0:0/device/vendor, but definitely no  /sys/bus/scsi/devices/host0/vendor

 

Why this happen? And how can I fix this?

 

Thanks.
