I don't know. All I see is SCSI errors. That shouldn't cause corruption, but then neither should Vinum. I'd suggest you attend to the SCSI problems and see if the others go away; I'd expect them to. If you want to follow the Vinum aspect, see the man page for details of how to solve problems. Greg -- When replying to this message, please copy the original recipients.
