Completion Status - Quantum LTO 2 User Manual

Completion Status

LTO-2 SCSI Interface Guide
Field
Long
Reserved
Control
If the Immediate (Immed) flag is set to 1, then the drive validates the
command and waits for any previous command from any host to
complete including any immediate commands currently being processed
and for any buffered data to be flushed to tape. It will then report a
deferred error for any preceding command or buffered data if
appropriate. If there is no deferred error, the drive reports good status
and initiates the command. If the Immediate (Immed) flag is set to 0,
status is not returned until after the command has completed.
If the Long bit is set, EOD is written at the current position. Data Set
Separators are then written from EOD to the end of the medium to
overwrite any data currently on the tape. If the Long bit is clear, then an
EOD is written at the current position marking it as end of data.
Table 22 shows the completion codes and messages for the
2
command.
