It just simulates a generic Tape interface. It seem to work with Solaris and Linux initiators. I think Nexenta did some limited testing with Netbackup and it was able to identify the tape drive.
I have not tested it with FC. FCP CONF and FCP-2 error recovery are not there in stt. But I don't know if that will impact basic tape functionality. It will be interesting if someone can give that a try.

It looks like drive type personalities are missing, though? That's pretty important for folks running traditional backup software (NetBackup, TSM, etc). Also, does it work over FCP too? Thx! -marc On Thu, Feb 18, 2010 at 3:17 PM, Erast <er...@gnusolaris.org<mailto:er...@gnusolaris.org>> wrote: Guys, just to let you know that Nexenta was working for quite some time on its COMSTAR VTape driver. It is now beta ready and feature complete as far as code is concerned: http://www.nexentastor.org/projects/vtape It requires b131+ to compile and run. Tested with NexentaStor and with many Backup vendors - results are very good. Yes, we hope to push this into OpenSolaris code base at some point and looking for Beta users. Originally code was contributed by Sumit Gupta, who is a well-know COMSTAR creator and former Sun's rock star! So, we sure that from design perspective our implementation is the best. Give it a try people!

This will achieve what you're looking for as far as devices. There is a project at Kenai (for the moment): http://kenai.com/projects/stmfssd that I believe Marc is referring to. I was somewhat hesitant about announcing it here due to uncertain Kenai future (thank you very much, Oracle), but I guess there is no real reason to keep silence. So, yes - the project aims creating virtual tape based on COMSTAR. Pretty much as Marc said it is in the early stage and contributions are very welcome.
