Mode Select (10)

Mode Select (10)
The 10-byte Mode Select command (55h) enables an initiator to specify certain
operating parameters for the library. The library uses the saved or default versions of
these parameters to configure itself during power-on or after a logical unit reset.
The mode values sent to the library apply to all initiators. If an initiator issues a
Mode Select command that changes any parameters, the library generates a Check
Condition status to all other initiators with a sense key of Unit Attention and an
Additional Sense Code (ASC) and Additional Sense Code Qualifier (ASCQ) of Mode
Parameters Changed.
When the library receives a Mode Select (10) command, the library validates all
parameters before it performs any changes. If a value is not valid, the library returns
the appropriate error message and does not change the parameters.
