Hmm, so what to do now? Does anybody have close relationship with Exabyte? At this time I'm sure that I can not kill dd process and in /var/log/messages there are no immediate errors - just deferred errors. But I still do not know, what commands flow over SCSI bus (is CAMDEBUG sufficient?). > have a deferred error (it's inherent in buffered tape i/o), but the drive > is supposed to know for further writes that it should send an immediate > error. If I can not kill -9 dd, are any further writes without dd possible? -- Rudolf Cejka (cejkar@dcse.fee.vutbr.cz; http://www.fee.vutbr.cz/~cejkar) Brno University of Technology, Faculty of El.
