SCSI EH and the Real World - Hannes Reinecke, SUSE Labs

Sign up or log in to save this to your schedule and see who's attending!

The current SCSI error handling has been modeled for the now rather ancient SCSI-2 standard. When working with modern hardware the error handling more often than not will lead to unforeseen results, interrupting I/O and occasionally disable LUNs altogether. Having been involved with several customer calls complaining I've been working on a patchset resolving some of the most pressing issues. This presentation will give you some real-life examples on what can go wrong, and present you with the results from the new EH. Finally I'll give an overview on the layout of a new EH, based on current standards.
