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

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.
