R730xd - CBL0009: Backplane 0 connector A0 is not connected (rear flexi-bay drives)

Hello

You are connecting the rear backplane to the integrated S130 connector. If you are using an H730 then the rear backplane should be connected to the front backplane.

Thanks

Many thanks for the quick reply... sorry for the stupid question but which connector would that be on? Can it be seen in the images posted up?

which connector would that be on?

Cabling instructions for the 3.5" backplane start on page 195 of the Hardware Owner's Manual:

www.dell.com/support/home/product-support/product/poweredge-r730xd/manuals

There are multiple configuration options, so find the 3.5" configuration that applies to you and follow that cabling guide.

Thanks

I'm having the same issue. We have two r730xd systems, both with the 24x2.5 inch backplane plus flex bay. We are receiving this error only on one system. Both systems have all the latest recommended firmware and are all cabled the exact same. One odd thing I noticed is when viewing the system summary in the idrac settings. Not sure what settings I need to modify to get this working on both systems. The system with 2 downstream logical slots works as expected. 

@jgrazulis Did you find a solution for this?
I have the same problem.

I'm having this EXACT same problem... I even posted a new thread in the forum before I found this one

Did you ever get this resolved?  

Start with checking the backplane mode through the iDRAC GUI: iDRAC > Storage > Enclosure > Setup, then edit from Split to Unified mode.

You will need to Power Off (Restart won’t be enough) the server to apply the change.

Hope this helps.

Chris,
I checked and I am already in "Unified" mode on my enclosures.  Could it be the SAS cable itself?  Do they do some sort of addressing in the cable?

Hello,

We are having the same issue as the first poster but in our case the front backplane is already connected to 2 H730p cards.

So we tried to connect the rear backplane to one of the J_SATA_* connectors but we get the error:

    "backplane 0 connector is incorrectly connected to Ctrl SATA B".

In our chase the ENCLOSURE config as noted above is set to 'SPLIT', which I assume means that the backplanes work independently. 

So.. how do we use 'backplane 0' and the rear drives when we have 24 drives and 2 x H730p cards?

Thanks

Chris

Hi,

The cable installation would be a mixture of diagrams shown here in the link between

https://dell.to/2xMM3Ah

I don't think it's possible to attach the rear flex bay to the onboard J_SATA as it will make use of the onboard S130 which might not be possible. 

I’m having the same problem.  Any solutions?   I don’t think it’s the sas cable. I unplugged it and the error was still there. Then if I unplugged the other 2, error was gone and obviously it wouldn’t see the flex drives 

I ran into this same issue and was able to open a case with Dell support, and they were able to determine the problem. I have a couple 24 bay (2.5") R730xd's, and I added the rear backplane myself. The rear backplane worked just fine but it had the CBL0009 boot error message. It turns out the rear backplane kit I used was originally for an R730xd with the 3.5" front drives, which is an entirely different front backplane. Somehow the iDrac/LC can determine which SAS cable is installed and will complain if the wrong one is installed. There is a different SAS cable for the rear backplane depending on what front backplane you have.

For the 24 2.5" front backplane, the cable part number is 8KX9H.

For the 12 3.5" front backplane, the cable part number is 8RJM1.

The wrong SAS cable will work and may fit, but the connector end angle on the front backplane may be less than ideal and the cable labeling won't be correct, and it will throw the CBL0009 error. Once I swapped to the correct cable everything worked great. The other two rear backplane cables - the signal cable and the power cable - are the same between the different R730xd configurations.

Hope this helps.

Hi!

Can you please tell me if the rear backplane can be used together with the front ones in the same RAID5 for instance? Or it is not connected to the H730P RAID Controller? If not, is there still somekind of possibility to create RAID1 for those drives?

Thanks,
Daniel

Danb,

You can use the drives in the front along with the drives in the rear flexbay, in the same Virtual Disk, as long as they are going to the same controller and are of the same drive type (SAS, SATA, etc).

Let me know if this helps.

Hi Chris!

Thanks very much, that's what I was curious about, exactly. And I guess that by default it is on the same controller, because I do not have any other in the server, just a H730P which manages the front bay, so it should work.
Great stuff, thanks very much!

Regards,
Daniel
