Connecting an NS372TB3 Netstor Enclosure

The Netstor has space for two LTO drives and built in Thunderbolt ports allowing direct connection to a Mac

Connect the unit

After connecting power connect a Thunderbolt cable and the drives will power on. Wait a few minutes for the drives to boot up. Open the YoYotta app.

Now click the LTFS button on the toolbar of YoYotta. This will check and prompt to download the LTFS frameworks needed.
Wait until the message Update completed OK appears.
YoYotta LTFS will now be able to control this drive.
Check the Support page to watch a video showing LTFS archiving along with links to all the help topics.

If the drives do not appear then follow the instructions below.
When the computer sleeps or is shutdown or the Thunderbolt cable is disconnected, the LTO drives will power off, so make sure that tapes are ejected.


Checking hardware devices

To check that the Mac can see the Netstor drive hold the alt key on the Mac keyboard, click the Apple Menu and select System Information...


Check for Thunderbolt devices

If the Netstor NS372TB3 is not shown, then check the power and try reconnecting the Thunderbolt cable.
If there is a Netstor thunderbolt interface, then the next step is checking for the SAS tape drive.


macOS 10.13 or newer System Security

The first time after you install drivers on a new High Sierra system, you will need to approve the new System Software. New installs of system software from YoYotta, OSXFUSE (developer is Benjamin Fleischer) and other drivers may need approval.
You will see a message like this saying System Extension Blocked
Open the Security & Privacy page in Apple System Preferences, unlock the padlock and click Allow to enable the System software to load.

You must click the Allow button directly on the Mac, clicking using remote screen sharing will not work.
If the Allow button is not shown then reboot your Mac, try again to use an LTFS or TAR tape (which will fail) and then check the Security & Privacy page again.


Check for SAS devices

Make sure the Netstor unit is connected and powered on, there will be a SAS unit which is the ATTO SAS interface, also one or two SCSI Target Device @ 0 and @ 1 are shown. These are the SAS tape drives.
If the SAS device is missing please contact support at Netstor for assistance.
