REQUEST SENSE (03h)
18.1 ABOUT THIS COMMAND
The REQUEST SENSE command requests that the autoloader transfer sense
data to the initiator. The autoloader provides sense data in only the Error Code
70h, extended sense data format. The autoloader returns a total of 20 bytes of
sense data to the initiator.
The sense data is constructed and saved on a per-initiator and requested LUN
basis. The autoloader preserves sense data for all initiators until the data is
retrieved by the REQUEST SENSE command or until the autoloader receives
any other command for the same I_T_L nexus (initiator-target-LUN
connection).
Sense data is available under the following circumstances:
The previous command to the specified I_T_L nexus terminated with Check
Condition status.
The previous command to the specified I_T_L nexus terminated with an
unexpected bus free error.
