Mode Parameter Lists
Following the command block, in the data out phase, the initiator sends a parameter
list containing the new parameter values of the library. This parameter list has the
same format as the data the library returns to a MODE SENSE command, with the restriction
that only one type of mode page per command is allowed for MODE SELECT. See the MODE
SENSE chapter for detailed descriptions of all mode parameters.
The following restrictions apply when reassigning element addresses:
• Element addresses must not overlap
• Element groups (i.e. cartridge slots, picker, drives) must be assigned contiguous
addresses
• Element addresses must be between 0 and 65,535
