Strange issue with PE840 and 2TB drives

Strange issue with PE840 and 2TB drives

Strange issue with PE840 and 2TB drives

Ok, this is a little strange. I bought a Poweredge 840 server off eBay and it came with a PERC 5/i card in it. My goal was to load it with 4 2TB drives and make a file server. Well, the issue is that when I go into the PERC bios, it only sees three drives out of four. It gets weirder still. It will only see drive 0,1 and 3. Drive 2 does not show up, even if i swap the cabling between let's say drive 3 and 2. Drive 2 still does show (the theory being if it were a bad drive or cable, the non showing drive would follow the change.

Wait, it gets weirder still. I can take out the 2tb drive and put in lets say a 1tb drive and it sees all four drives. three 2tb and 1 1tb. Wait, it gets weirder still. I can put the 1TB drive in port 0 and the three 2TB drives in 1,2 and 3 but again port 2 doesnt show. The ONLY WAY I can get all the drives to show is to put the 2TB drives in port 0,1 and 3 and then put a smaller drive on port 2.

I have upgraded all firmware and drivers on the system to no avail. Im wondering if its a limitation on this card but i've never seen that and no one else seems to have either. I can contact Dell as this is out of warranty. I was also thinking it might be a PSU limitation as I know those 2TB drives take a lot of power. What I haven't tried was to see if just one 2TB drive on port 2 shows up. Maybe port 2 has a limitation for some weird reason.

Any thoughts would be helpful.

I would try calling Dell anyway, I had a server out of warranty and they helped me rebuild a drive that dropped out of the array


RE: Strange issue with PE840 and 2TB drives

IIRC, the server comes with lifetime phone support, even if the warranty is expired. Actually fixing the problem is on your dime, but you should have no difficulty talking to a tech and getting a case opened.
