Mode Sense Command
The Mode Sense (6) and Mode Sense (10) commands return the current
operating modes and parameters of a device to the host. The Mode Sense
commands also return the default parameters or information on which fields
and bits can be changed using the Mode Select command. The device returns
a header, block descriptor, and one or all supported pages following the block
descriptor.
Note:
The tape drives support both 6- and 10-byte commands. The Mode
Sense (10) command allows for a longer Allocation length, but
otherwise operates identically to the Mode Sense (6) command.
