SCSITAC Sections Table 7 SCSIDLT Sections SCSITAC contains three sections: • Section 1: Verification Trouble Tree • Section 2: Hardware Trouble Tree • Section 4: Interactive Sections 1 and 2 perform tests on the library, report results, and return to the DUI prompt. Section 4 provides users with a SCSITAC prompt, which accepts the following commands (Table 7). SCSITAC Interactive Commands Command Function devreset Performs a SCSI device reset. download Downloads firmware. The user may place the download file anywhere on the host system. The download command will prompt the user to enter the fully qualified filename. exit Exits the interactive section. inquiry Performs a SCSI inquiry. help Displays this list of commands. tur Performs a SCSI Test Unit Ready. SCSIDLT contains four sections: • Section 1: Verification Trouble Tree • Section 2: Hardware Trouble Tree • Section 3: Destructive Hardware Trouble Tree • Section 4: Interactive Sections 1, 2, and 3 perform tests on the library, report results, and return to the DUI prompt. 32 Diagnostic support tools
