SDLT 600 SCSI Interface Guide Chapter 4: SCSI Commands

81-81200-02 REV A01 January 2005 4-29

Load If the Load bit is set to 1 and the medium is already loaded, the drive writes any

cached data to the tape, rewinds the tape, and returns a GOOD status. If the drive

unloaded the medium but the cartridge was not removed, a LOAD UNLOAD

command causes the drive to load the tape to Beginning of Partition (BOP) again

and make it ready for use.

If the Load bit is set to 0 and the medium is loaded, the drive writes any buffered

data and filemarks to the tape, rewinds the tape to BOM, and unloads the

medium back into the cartridge. At that point, the drive ejects the medium if not

in a library. If the drive is in a library, the drive does not eject the medium, but

waits for another command. If the medium is already unloaded, the drive takes

no action. The drive returns a GOOD status.
