Hi guys.
First of all, I highly doubt they'll sack you for something that wasn't your fault

And if they do, as you've had no training...you could probably file a lawsuit for unfair dismissal (I'm not a lawyer though, so i don't know for sure)
But are the drives "glowing red" or are the lights? That's where i'm confused
Also, if there are 3 hard drives, if they are all identical, then they will be in RAID5...unless the guys who your company bought this server was were completely unknowing and "newbish" as the term goes.
To be honest, I think at least 2 thirds of your data is lost, and you company is going to have to replace the other 2 hard drives.
This is definately not your fault, as 2 failing at the same time? That's almost unheard of.
