NO SENSE: Indicates that there is no specific sense key information to be reported

 

 

 

for the designated logical unit. This would be the case for a successful command or a

 

 

 

command that received a CHECK CONDITION or a COMMAND TERMINATED

 

 

 

status because one of the Filemark, EOM, or ILI bits is set to one. For Filemark or

 

 

 

Setmark detected the drive will be positioned on the EOM side of the mark if the drive

 

 

 

direction was forward and on the BOM side of the mark if the direction was reverse.
