Worked for an MSP, we had a large storage array which was our cloud backup repository for all of our clients. It locked up and was doing this semi-regularly, so we decided to run an "OS reinstall". Basically these things install the OS across all of the disks, on a separate partition to where the data lives. "OS Reinstall" clones the OS from the flash drive plugged into the mainboard back to all the disks and retains all configuration and data. "Factory default", however, does not.
This array was particularly... special... In that you booted it up, held a paperclip into the reset pin, and the LEDs would flash a pattern to let you know you're in the boot menu. You click the pin to move through the boot menu options, each time you click it the lights flash a different pattern to tell you which option is selected. First option was normal boot, second or third was OS reinstall, the very next option was factory default.
I head into the data centre. I had the manual, I watched those lights like a hawk and verified the "OS reinstall" LED flash pattern matched up, then I held the pin in for a few seconds to select the option.
All the disks lit up, away we go. 10 minutes pass. Nothing. Not responding on its interface. 15 minutes. 20 minutes, I start sweating. I plug directly into the NIC and head to the default IP filled with dread. It loads. I enter the default password, it works.
There staring back at me: "0B of 45TB used".
Fuck.
This was in the days where 50M fibre was rare and most clients had 1-20M ADSL. Yes, asymmetric. We had to send guys out as far as 3 hour trips with portable hard disks to re-seed the backups over a painful 30ish days of re-ingesting them into the NAS.
The worst part? Years later I discovered that, completely undocumented, you can plug a VGA cable in and you get a text menu on the screen that shows you which option you have selected.
I (somehow) did not get fired.
You still remember so. That means you learned and probably won't do it again.
