Hello Bart Thank you for this. Indeed, That's on my plate for next year to try rework this into the target core. Its used a lot here at Red Hat for testing the F/C drivers and multipath via the LIO target server. The first version of this is already in that allows jamming of all commands. I wanted to share the enhancement which is very useful and has been working well here but indeed if we have this in the core its better. I may have some questions for you as I work on that next year. Many Thanks Bart for all your help this year.
