Hello,

i Have been trying to pass through a TC-L52BN LTO 5 Tape Drive from Quantum that's connected to a MegaRaid SAS 1068 LSI Raid Card, this setup works if i have a bare metal installed Proxmox Backup Server. I Have IOMMU Enabled on the Proxmox Host and Passed through the Raid Card to the VM. I can Also see the Raid Card With "lspci" from inside the VM but the "proxmox-tape drive scan" command and the UI can't seem to find it. Is there Any Additional Setup i have to do / any Troubleshooting steps i could follow?

Thanks,
Samuel


Hi,

did not try such a setup myself, but is the passthrough properly working? I.e. do you see any other disks that are connected?

Is the correct driver loaded for the raid card?

Also what does 'dmesg' show?

kind regards
Dominik
