The operating system is based on CentOS 4.4, but is modified, and runs a proprietary file system. It has pretty good performance and I'm happy with it. > > You may know that the company went bust some years ago, so I have been running this system unsupported.

Unfortunately, what I know about fibre channel is very little. They are emulex HBAs, and I guess there used to software called lputil, but this is no longer available at the Emulex site. It has been replaced by something called HBAnywhere, but I have not succeeded in building that on CentOS 4. Uprading the OS is out of the question I would think while maintaining the file system capability. > > And the other question is how to manage the LUNs on the Xyratex's. > > I'd be grateful for any info anyone has on either. > > Tony Schreiner Have you tried to locate ex employees of that Company?
