Hi Wendy! > I am going to re-do V2 patch with retries. Is it ok? We probably do not want to blindly retry on all errors. We should only retry in cases where the command has the potential to subsequently succeed. Hence the request to retry "transient errors" in my previous mail. Classifying which errors should result in a retry is the important piece. And for that we need to know exactly what error your tray is returning. I also suggest you have a look at scsi_check_sense().
