I don't think it can be done by USB. The SAS-to-USB chips operate in
"mass storage" mode, suitable for SAS hard drives. The LTO drive will
need an adapter that operates in SCSI emulation mode. I don't know of
any adapters that aren't strictly for hard drives, but maybe there are.
Another approach is to use a Thunderbolt port instead. Thunderbolt is
essentially an encapsulation of PCI-e. There are many Thunderbolt PCI-e
Expansion chassis available that are simply one or more PCI-e slots
connected via Thunderbolt (but with their own power supply). You can
insert a PCI-e SAS controller in the expansion chassis and the server
will treat it exactly like one of its own PCI-e slots, so the OS will
see the tape drive in exactly the same way and so then would Bacula.

I have worked for lab and training with DDS3 USB drives.
you detect them the same as scsi (lsscsi -g) Of course here you don't
see the "mediumx" you only see the TAPE , you don't declare
autochanger, only the devices

Hi all,
This might be considered slightly off topic but has anybody tried
installing USB3 PCIe card in an external LTO tape drive?
Many models appear to have 2 slots with only one occupied by SAS by
default, e.g:
https://www.bechtle.com/de-en/shop/quantum-lto-7-hh-sas-external-drive--4038311--p
The idea would be for the tape drive to operate via SAS 99% of the
time
but occasionally move it elsewhere and easily access via USB (from
any
desktop or laptop).
Somebody has done it before on a factory level:
https://www.fujifilm.com/in/en/business/data-management/datastorage/lto-tape-drive/brochure
but I would prefer not to be limited and locked to this one
particular
model + software.
I'm assuming that I should still be able to run Bacula with the above?
Any advise?
Regards,
Adam
