Mode Sense (6)
The 6-byte Mode Sense command (1Ah) enables the library to report its operating
mode parameters to the initiator.
• The initiator can request one page or all pages of the mode parameters.
• The initiator can use the Mode Select command to change the values of certain
mode parameters.
• Before issuing any Mode Select commands, an initiator should issue a Mode Sense
command with the Page Control field set to 01h, and the Page Code field set to
3Fh to determine:
• Supported pages
• Changeable parameters within the pages
• Supported length of each page
