The ScsiCmd Tool is used to test whether the hardware supports SCSI-3 reservation. (SCSI-3 reservation is used when you enable the Use SCSI Reserve for contention resolution option in the Library Properties dialog box.) This tool is installed along with the MediaAgent software and available on all the MediaAgent computers. The following section provides the steps for using this tool. |
