Here is a demo on how to take a machine running Solaris and convert it into a Fibre Channel Array using COMSTAR and ZFS. The demo covers all the steps starting right after a fresh install of the OS to seeing the FC LUNs from different initiators (Solaris, Windows and Linux) connected to the Solaris Host acting as a FC storage array. But still this is around basics. There are some concepts like LUN mapping and masking and using some advanced zfs concepts which are not covered in this demo. I hope to add more content in future which will cover those aspects.
This Demo is also posted to the Videos section of the COMSTAR project page.

Great demo!.

How about adding redundancy? In a typical SAN storage you will see dual controller mainly working in tandem to make sure there is no downtime w.r.t failure of any of the controller. How do we do it with COMSTAR?
But the Demo was great! :)

Sumit,
Very well done. It would be a great help to be able to capture the series of commands you type to do the work. I will have to stop the video and copy each command carefully. The script for FC discovery would be a nice touch here as well.
The comment related to redundancy deserves a short reply: is it possible? Then provide the details as time and schedule allows.
I hope to see more videos of this quality from you. It's appreciated. I know it takes a lot of time to get it tested, documented and captured. But it will save those that follow all those hours of research, debugging and trial and error.
