Perc 6i drive missing

I have 4 drives in RAID10. One of them is missing, but I'm not sure how to tell which of the drives it is. I checked all the cables which are OK.

i take it its a dell server, in which case you could use dell open manage or the bios of the card

no, its a server i built myself. I'm not sure how to tell which drive is which in the Perc BIOS.

inside the bios does it show the drive serial number? may have to remove each drive to see if it matches and see which doesn't appear in bios

No just the drive manufacturer. Can I hot-unplug the drives in turn without messing up the array?

i wouldn't like to say 100% you could do that with no problem, but i have before now done that, having said that i didn't have to worry about loosing important data.

its hard to say what is the right thing to do as i cant see the setup, if you have 4 drives and they were all connected in order 0,1,2,3 and the perc card saw them in that order, you'd see which number is down. but im taking it you tried all the obvious?

Now the drive is showing as failed;

Isn't it just as easy to look at the cabling, I'm assuming your using a break out cable, and its plugged into port 1 instead of 0 which is why the disks at 4,5,6,7 instead of 0,1,2,3?

So failed disk 6 would be cable 3? Or am I missing the point?

I am using a breakout cable but I did not label it with numbers.

They're normally labelled, maybe not with tabs but on the cabling there will be something to distinguish each cable.

Old skool way.

After some heavy activity.. Feel which drive is significantly colder than the rest, and if you're able, touch the drives during activity (use a screwdriver to help hear if needed) as the failed one should be the only one not hammering away.
