Yes. FCP (FibreChannel Protocol) is a derivative of the SCSI command set and looks just like it from the operating system's perspective. Odds are the same high-level SCSI driver in the Linux kernel would be used in both cases (SCSI & Fiber) so mtx will probably work out-of-the-box if you have the driver for your FC card installed properly.
That said, you want to watch out for a few things: 1.) FibreChannel SANs, and the cards that connect you to them, are tuned differently from SCSI busses. Check and re-check parameters like blocksizes and make sure you know what the settings on both your SAN switch and interface card are. 2.) Verify whether the tape drives in your autochanger are FC-native (they speak to the SAN switch directly) or bridged (they use a SCSI->FC bridge). If they are bridged, that is another device whose settings you should double-check. 3.) Watch out for any kind of buffer caching in the SAN between Bacula and the tape drives, especially if the drives are bridged. Different devices might have different-sized buffers and not flush them before signaling the end of a write operation to the operating system. In order to keep Bacula sane, all buffers on all devices should be flushed before IO operations are reported to the OS as complete. --PLB At 17:24 26.10.2007, Flak Magnet wrote: >I currently have a Quantum-SL3 autochanger working with Bacula running on >Solaris with a LVD-SCSI connection. > >We're looking at acquiring a 2nd one and attaching it via fiber channel to a >Linux host and "driving" that one with Bacula too. > >The MTX compatiblity page doesn't have any indication of what kind of >connection (SCSI vs Fiber is being used and I think that SCSI is probably >more prevalent than fiber. > >Does anyone on the list have any experience with autochangers and fiber >channel connections working with MTX (and therefore bacula)? > >I have found the following: >http://article.gmane.org/gmane.comp.bacula.user/30699/match=fiber+channel >So apparently Mike Seda a FC connection working >and: >http://article.gmane.org/gmane.comp.bacula.user/38666/match=fiber+channel >So Arno indicates that fiber channel "looks like SCSI" to the OS, >therefore to >MTX. > >So I'm pretty confident that we'll be all-set, right?
