ITDT is a utility provided by IBM for interacting with LTO drives and can be used for many tasks, typically we may ask you to use it to collect drive logs (aka drive dumps) or to update the firmware of a drive.
ITDT-SE for Mac is available for download at the bottom of this article.
Once downloaded, double-click on the zip file to extract it's contents.
These instructions assume the downloaded file is in the default Downloads folder, this is how to use the itdt command line tool to scan for attached LTO drives.
Open Terminal (found in /Applications/Utilities/Terminal) and drag the itdt file in to the Terminal window
Press the right-arrow key to send the Terminal cursor to the end of the line and type scan and hit Return
A warning appears informing you that the developer cannot be verified
Open System Preferences > Security & Privacy > General and click the Allow Anyway button
Return to the Terminal window and hit the up-arrow to run the same command again
Another warning about the developer not being verified appears, click Open to continue
Lastly itdt requests access to the Downloads folder where the command is stored, click OK to continue
That's it! You've successfully installed ITDT-SE for Mac and performed your first scan to detect a connected LTO drive.
