SCSI Commands: 18BLOAD UNLOAD Page 41
If the immediate (IMMED) bit is one, 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 bit is zero, status is not returned until after the
command has completed.
