Scsi Log Pages

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
