When the server boots it’ll ask you what you want to do about rebuilding the mirror. We took the 2 GB card out, put our new 4 GB card in, and put everything back together.Ħ. The SD card locks in, so you need to push it in to eject it. Your mileage here will vary - 11G servers had the slots labeled, and I haven’t looked at a 13G IDSDM yet. But now that we’ve got the thing in our hands which card is SD2? Turns out on 12G PowerEdge IDSDMs there’s an activity light on each side, and one is labeled SD1_LED and the other is SD2_LED. The error in the system event log indicated that SD2 was faulty. Last, the IDSDM has a little blue strap to help you pull it straight up and out of the socket.Ĥ. Then we gently removed the PCIe riser itself. We took the expansion cards out of that PCIe riser and noted which one was in what slot (top vs. The Dell IDSDM whitepaper indicates that, because of the way the module is powered, you should always do this work with the AC disconnected.ģ. On blades it’s out the back, labeled “SD,” and you just have to pull the blade out to get to it. On our PowerEdge R720 it was below the PCIe riser closest to the power supplies.
Second, we shut the host down, unplugged it, and found the SD card module using the map under the Dell server cover. After all, I do have a couple hundred of these things.Ģ. Plus, if one has failed I suspect I’ll see another failure. Why two cards? Because the staff time & fuel costs more than the part, so stocking a spare makes sense. The SD card from Dell was Kingston so we chose that brand. First, the SD cards themselves are not covered under Dell warranty, so we bought a new 4 GB card (the smallest we could find) from the nearest place that sold them (try your nearest Walgreens or CVS). This is also good advice for fueling your car in dry climates. Just remember to do it again if you wander off and come back. Touching the metal portions of the case works well for this, which you clearly have to do to get inside a PowerEdge. I always suggest you manage possible static electricity by ensuring you’re at the same electrical potential as the server. To me this is a real easy fix, but you should do what you’re comfortable with. Note: I’m certified to work on Dell servers, and have been messing with hardware for 25 years. We’d never seen a failure like this so we had no idea how to fix it, and the Internet was only slightly helpful (hence the point of this writeup). The other day we received an alarm: Failure detected on Internal Dual SD Module SD2 Ours are populated with two 2 GB SD cards from the factory, and set to Mirror Mode in the BIOS. It works great, and saves us a bunch of money per server in that we don’t need RAID controllers, spinning disks, etc. We use the Dell Internal Dual SD module (IDSDM) for our VMware ESXi hosts.
