ML10v2 Drive Cage

115 posts in this topic

OK, looking at the parts, I can see that my backplane is identical to LoneWolf's. Part numbers, etc., and the little black boxes at the top next to the connectors are actually covers that come off and the contacts are behind them just like LoneWolf's.

 

I'm wondering now if that is the reason I didn't appear to have power to the drives because the covers were keeping the sleds just a millimeter or so from being able to correctly contact the power contacts in the connectors. Drives appeared to be seated, but maybe they weren't.

 

Now I'm going to have to give it another go at the end of next week when I have some more time. Damn :)

 

On one side of my drive caddies you can see HP molded into them. Don't know if they are original HP parts though. I seem to remember the caddies from the HP ML350 Gen3 I was messing around with had very flimsy caddies also, so I don't think that is really an indicator.

Will try and post some pics of the finished install even though it didn't work (YET).

Icydock at top contains 3TB server backup drive. Icydock below contains half height DVD drive and 2 2.5" WD Black OS drives in raid 1. Connected to HP P120i

 

Now to hit preview and see how it looks :)

 

Great, works again. Thanks guys !

LOL, I'm sure it will work this time (fingers crossed) now that I discovered the plastic protective covers over the contact pins. Very strange there wasn't some kind of marking or warning to take covers off before using. 

 

I guess I could blame LoneWolf for not mentioning them, but maybe his didn't come with the covers :)

Mine did not come with covers.

I figures as much, your documentation has been great so I assumed when I finally figured out they were identical backplanes that yours must not have had them. Alls great now that I know what the problems is :)

Did the reinstall minus the protective covers today and same result. Can't figure out what the heck is going on. Maybe got a bad backplane. I'm going to leave well enough alone I think.

 

I might just trim off the bottom lip of the hot swap case so the stock power/data connectors fit and at least not have to pull everything apart to just change one drive. Can unplug it from the back and just pull it our from the front. At least that would be an improvement.

 

I've just ordered the backplane that uses the stock connectors. Don't really need hotswap. Just convenience when changing drives.

Well, it looks like linking pictures works again.  Let's see if this flies.  The one change is that all four drives in the IcyDock are now filled.

And, an image to show the connection of the backplane.  The two PCIe cards are my Smart Array P420 and an Intel Gigabit ET server NIC.  Anyone making the switch will need an SFF-8087 (both ends) cable to replace the SFF8087 <-> 4xSATA that is there; it just so happens I had one that came with an LSI RAID controller I acquired some time back.

LoneWolf, it was just plug and play with the power connector for the backplane? I don't remember anything being said about pinout issues, so I'm assuming my backplane didn't work because of some other issue.

It is just that.  There are three possible reasons yours didn't work that I can think of.  All involve the SFF8087 (MiniSAS) cable.

 

1)  The SFF8087 cable is loose either at the motherboard (or RAID controller) or backplane.  This can be touchy, getting it to click can take a bit of finessing.

2)  If the SFF8087 cable is plugged in the wrong way at the motherboard (not possible on the P222 controller, but it is on the B120i) or the backplane.  If so, things won't come up, though the server will power on, nothing's going to light and it won't find the drives.  Your picture looked correct on the backplane; the latch on the cable should be facing outward.

3)  You have a bad SFF8087 cable.  That'd do it too.

 

The less likely options would be if your drives aren't seated properly (I definitely had to seat mine with the cage and backplane outside the server the first time, they should be good from now on), or if the backplane is bad, but I'd doubt it, yours sounds new.  Mine looked new but was advertised "used" and came with no plastics as previously mentioned so it probably is.

I've got an RMA to send the backplane back. I've also got the steel backplane ordered that lets you just attach the standard ML10 sata/power connectors. So I'll just stick to those I think. About $100.00 cheaper too :)

Too bad you're in Oz.  I would have worked something out with you for mine. :D

I can always use a spare SFF8087 cable so maybe I'll order another one before I send the backplane back.

Oh.  I meant I would have made you a deal on the backplate and cable assembly. :) (now that I no longer need mine)

 

But trying another SFF8087 cable isn't a bad idea either.

I sat here trying to wait quietly, but now i'm just too curious to not ask:  What's the latest on your drive cage gibster??

Well the latest is :)

 

I did the reinstall of the cage, caddys, and the new SFF8087 cable and low and behold, all the lights flash on the caddys and then I wait and wait and wait but the P222 never shows up as being installed or active. So, I take off the backplane, reinstall the stock cable, hook the connectors up the drives in the new cage and then the P222 shows up with the drives and everything is working again, except of course the lights on the caddys.

 

So I don't know what the heck is going on. I don't know why the new backplane would keep the controller from registering with the system. I'm stumped. I would have though it there was some issue with the backplane the controller would have just said there were no drives attached to it, and not have the controller show as not even be installed in the system.

 

I'll RMA the backplane since the vendor said they would keep the RMA open until I had tried the new cable.

 

Weird problem.

Does your SFF-8087 cable have the optional sideband wires? The RAID controller uses those extra wires to communicate with the drive enclosure processor and this includes the extra LEDs on the caddy.

I think the first cable I had didn't. When powering on the server no lights would show up or blink.

 

With the new cable when powering on you can see all the lights cycle on the caddys. But after that there are no lights and no indication that you have a disk controller installed other then the stock P120i that shows up. You can see leds on the P222 illuminated so I know it's getting power. 

 

The controller doesn't show up in iLO.

I got my cage in last week, still not sure if i'm gunna buy the backplane or back plate, AFAIK the backplane does not work them leds with a LSI card anyway... so might as well save the money and go with the non-hot plug... did anyone ever used a non-hp controller with a hp backplane??
(yes the LSI does support SGPIO but HP most likely uses proprietary signal to get them leds going.)

By the way, why are the hd trays $33,- each (and above that if you buy them in a normal store) 
Does anyone know a cheap source for them trays??

In the US, the trays were $10USD each plus a buck or two for shipping. eBay was the easiest place to find them. Might be an international seller who offers similar pricing.

Wonder if this will work in MLOv2?

 

if it has all the parts needed, doesnt say how it connects...

 

The question is whether the picture is correct for the part, something I've seen vendors screw up.  Use the part number to do more research.  If it's the same part as used for the ML30 Gen9 or the ML310e Gen8/Gen8 v2 it will work.  Also, if the picture is correct, that should work, as that looks like the one for the ML30 Gen9.

 

The way it connects is that the power supply has a connector that goes straight to a power connector on the backplane board.  You use an SFF-8087 cable to go from the mainboard to the backplane.  Note, you will also need drive sleds.  See my pictures in this post from page 3.

I've ordered a hot-swap cage (PN 686756-002), 4 3.5trays and one minisas cable. Hopefully will get them by tomorrow.  Cost me about $50 in total.
