hi,

im new on PVE and PBS.
we have old HP ML 350 G5 with 6 disk SATA:
- 2 x 1 TB (Raid 1)
- 4 x 2 TB (Raid 5)
and connected via SAS LTO-3 (HP Ultrium).

Is any chance to use LTO-3 with PBS?
(Yes, i know is old and small, but work o_O )

Or maybe better - can i connect LTO-3 to VM and use it?

Hi,

No, I'm afraid, LTO-3 is from 2004, just far too old and does not support important features that PBS Tape support relies on (even LTO-4 has some drawbacks and is only supported as best-effort).

Or maybe better - can i connect LTO-3 to VM and use it?
You can pass through SCSI devices, so yes this may be possible. It should be relatively similar to passing through disk scsi devices:

disclaimer: I do not have any LTO-3 device, so did not test this at all - but maybe worth a try.

I tried for 2 days and it's not that simple.
Connect device to PVE and try to add this to VM/Container.
Unfortunately, none of the solutions from link worked.

I was looking for a solution and in general there are two options:
1. add PCI device to VM (KVM)
2. share lto-3 via iscsi (this option is better for me)

https://pve.proxmox.com/wiki/Tape_Drives

So, PBS will have lto-3 - but will not use it, only share via iscsi.
One VM/Container will have the device connected via iscsi.

PBS is like a mountain always in the same place (LTO3 too),
VM can be on different PVE.

next week I'll keep trying
