A firmware update stops part way through. What do you do?
Why A is the answer
Check logs, and follow the recovery procedure
Blind power cycling can make recovery harder.
In detail
- Blind power cycling can make recovery harder.
- Blind power cycling can harm recovery.
Use case
An illustrative scenario, not a real incident.
A firmware update stops, so a technician checks logs, rather than cycling power blindly.

Why the other options are wrong
- B. Power cycle it again and again until it comes back up
- That can make it worse.
- C. Replace the entire rack without any diagnosis
- A whole rack is far too much.
- D. Install the OS again and ignore the firmware
- Firmware must still be fixed.
