Jukebox SCSI-2 Commands NOTE Table 3-64 Jukebox SCSI-2 Command Set Log Sense Command (4DH) Retry Log Data Format This log is ONLY supported on the 40fx, 80ex, 125ex and 220mx models. This table can be accessed via the Log Sense Command (4DH), Table 3-45 on page 3-47, with page code 39H. Each retry algorithm code byte triggers a specific retry algorithm on the preceding move command. The byte order is the same order in which the retry algorithms were run. Retry Log Data Format Byte Description 0 Page Code 39H 1 Reserved = 0 2-3 Number of bytes to follow 4-103 Retry Algorithm Code (Table 3-65 on page 3-62) 104-105 Number of Inline Retries 106-107 Number of Major Retries The last four bytes may be organized as two 16 bit words. The first word is the cumulative number of Inline Retries (since the jukebox was built), and the second word is the cumulative number of Major Retries (since the jukebox was built). Inline Retries are attempts to move again from the error position. Major Retries are attempts to move again after a Find Home command has re-zeroed the unit. Chapter 3 3-61
