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
