SCSI target devices provide a number of SCSI log pages. These can be interrogated by a Log Sense command and in some cases can be set by a Log Select command. The Log Sense and Log Select commands include a 6-bit address field, allowing for 64 possible log pages. There is a standard map of log page addresses below. Note that any given SCSI device type will only support a subset of these log pages. 00h - supported log pages 01h - buffer over-run/under-run 02h - error counter (write) 03h - error counter (read) 04h - error counter (read reverse) 05h - error counter (verify) 06h - non-medium error 07h - last n error events 08h-2Fh - reserved 30h-3Eh - vendor-specific 3Fh - reserved SCSI
