After being powered off and unplugged for a few weeks the CAN issue that I'd been having with the i6000 seems to have resolved itself. However the LTO-6 tape drive/sled I have isn't powering up at all. IDK what's going on with that. The error is that the barcode on the drive isn't recognized. This is caused by the system not having the drive registered via the system bus. Which in this case is caused by the sled not powering up.
