Supported SCSI commands
An introduction to the SCSI commands that are recognized by the TS4500 tape library.
Table 1 lists all of the commands that are defined by the referenced SCSI-3 standard for medium changer devices and that are supported or not supported by the TS4500. For each command, the operation code, applicable SCSI-3 standard, and applicable conditions are shown.
For the SCSI commands supported by the IBM® LTO Ultrium tape drives, see the IBM LTO Ultrium Tape Drive SCSI Reference.
For the SCSI commands supported by the IBM 3592 tape drives, see the IBM 3592 Tape Drive SCSI Reference.
