Status and Error
Reporting

SCSI command-level errors are communicated by a status code that the
drive returns during
STATUS. This occurs at the end of each command
unless one of the following events terminates the command:
•
ABORT TASK, ABORT TASK SET, or CLEAR TASK SET task
management function is processed so that it affects the command.
•
TARGET RESET or LOGICAL UNIT RESET task management function
is processed.
• Reset condition
• Unexpected disconnect (Parallel SCSI only).
Table 11
describes the status codes the drive returns.
