Hi! I think, I have found the problem with SCSI-Tapes (Error 80000). I have detect, that the sgraidmon is testing all sg-devices, and if the inquiry-command fails (timeout) it sends a bus- reset-command (ioctl) as "recovery"-operation ! After stopping the sgraidmon I have no more problems with the tape. Can anybody confirm this? -- Robert Valentan - : send the line "unsubscribe linux-scsi" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
