PBS will not detect Quantum Superloader 3 tape library

[jadano]

Hi,

I'm new to Proxmox.

We just purchased a Quantum Superloader 3 LTO8 Tape Library and it isn't being detected by our PBS.

Running proxmox-tape drive scan returns nothing.
Running find /dev/tape -ls returns nothing.

Here is our hardware:

Lenovo ST550 tower server /w a Lenovo STA 430-8i SAS/SATA HBA
Quantum Superloader 3 IBM LTO-8 SAS / Autoloader Version V100.0 (0065.0h) / Drive Version: MA71 / SAS Hashed Addr: 0x01430c

Any help would be greatly appreciated.

Thank you in advance.

Quantum Superloader 3 LTO8 Tape Library work perfectly here.

Seem not even the kernel detects your device, so maybe something else is wrong. Already checked the cables?

also, can you post the output of 'dmesg' ?

@dietmar and @dcsapak - Thank you for your replies and sorry for the delay in response.


I figured it out. The issue was the Lenovo ST550 server we are using only has one CPU installed, so depending on what PCIe slots you install them on (in my case I was trying to install on PCIe Slot 4 or 5) which is looking to process on CPU 2, it wasn't being detected. I moved the HBA controller to PCIe slot 3 and viola, it detects no problem.

The following Lenovo documents helped point me in the right direction:

Expansion slots​

The server has six expansion slots on the system board for installing appropriate Peripheral Component Interconnect Express (PCIe) adapters.

• For processor 1
  • PCIe slot 1: PCIe x8 (x8, x4, x1), full-height, half-length
  • PCIe slot 2: PCIe x16 (x16, x8, x4, x1), full-height, half-length
  • PCIe slot 3: PCIe x16 (x16, x8, x4, x1), full-height, full-length, double-width
  • PCIe slot 6: PCIe x8 (x4, x1), full-height, full-length
• For processor 2
  • PCIe slot 4: PCIe x16 (x8, x4, x1), full-height, full-length
  • PCIe slot 5: PCIe x16 (x16, x8, x4, x1), full-height, full-length, double-width

Thanks again for you help!
