[BlueField DPU -- DOCA Management]

When upgrading DOCA on a BlueField DPU, what command should first be run on the host?

Show Suggested Answer Hide Answer
Suggested Answer: B

Before upgrading the DOCA SDK on a BlueField DPU, it is mandatory to uninstall the existing OFED drivers to prevent compatibility conflicts.

From the NVIDIA DOCA Installation Guide:

'Before upgrading DOCA or BlueField-related software, you must remove existing OFED packages using: /usr/sbin/ofed_uninstall.sh -force.'

This ensures:

Clean driver state

No residual kernel modules or userspace libraries

Proper registration of new DOCA/OFED versions

Incorrect Options:

A and C may not resolve conflicts.

D installs but doesn't remove conflicting packages.

I’m leaning towards C too. Upgrading should be the priority.

Upgrading DOCA? I just want to upgrade my snack supply. Where's the vending machine?

A) sudo apt-get autoremove? Hmm, that's for removing unused packages, not upgrading DOCA.

I remember practicing a similar question, and I think it was about installing packages. Could it be D?

I think the key is that the question specifically says "on the host". That makes me think option C or D might be the way to go, since they involve using apt-get on the host system.

I'm a bit confused here. Does the question mean we should run the command on the host, or on the BlueField DPU itself? That could make a difference in the right answer.

I think the command to run first is related to ensuring the system is clean, so maybe it's A? But I'm not entirely sure.

Okay, let's see. I'm pretty sure we need to uninstall the current DOCA version first, so I'm leaning towards option B.
