next SCSI command (except INQUIRY and REQUEST SENSE

 

 

commands) following detection of the condition. The Sense Key is

 

 

set to RECOVERED ERROR with an additional sense code of 5D 00

 

 

(TapeAlert Event). The SCSI command with CHECK CONDITION

 

 

completes without error prior to the report of any exception

 

 

condition, and does not need to be repeated.

 

06h

Only Report Informational Exception Condition on Request. The

 

 

device server preserves information exception data. To access the

 

 

data, a poll can be taken by issuing an unsolicited REQUEST SENSE

 

 

command. The Sense Key is set to NO SENSE with an additional

 

 

sense code of 5D 00 (TapeAlert Event).

 

 

The additional sense code of 5D 00 for values 03h and 06h signals

 

 

that a TapeAlert has occurred. Information about the event is

 

 

stored in the TapeAlert Log Page. The setting of MRIE does not
