cat /proc/fs/lustre/lov/*/target_obd

I forget which version this bug appeared in, that the lctl command does 
not show the IN state.  I am hoping it will be fixed in the 2.8 release 
as it is really annoying.

So the command certainly seems to be working, it is just that the lctl command isn't showing the device as IN.
