LOG SENSE Command (4Dh) (continued)
5.8.6 Device Wellness Page (33h)
The Device Wellness Page returns information about any check conditions
related to Sense Keys 1, 3, 4, and 9 logged by the tape drive. Up to 16 entries
(parameter code 0000h to 000Fh) can be contained in the page; each entry
records a check condition (Sense Key = 1), a medium error (Sense Key = 3), or
hardware error (Sense Key = 4). Note that parameter code 000h contains the
oldest log information while parameter 000Fh contains the most recent.
Only head cleaning recovered errors (more serious recovered errors) are recorded
when Sense Key is 1; all sense data are recorded when Sense Key is 3 or 4.
This page begins with a 4-byte header followed by the log parameter blocks.
