What warning message?11.2 RC2 is the only update from 11.2 to include this message warning.
The one you have highlighted in yellow on your last screenshot.What warning message?
I have the two hb-1235 controllers almost here (Canada Post on Strike) and will test with them when they arrive.
i also bought a used Netapp ds4246 on ebay a couple of weeks ago. I put a couple of SATA 8x8 TiB raidz2 pools in it . I have a flashed M1015 IT mode (p20) SAS HBA adapter in my main chassis. I notice there is some SAS negotiation errors on boot-up. I have both IOM6 adapters engaged. I watched a video on youtube by Morten Hjorth that has the same or similar chassis with one IOM6 module unplugged. I think unless you have SAS multipath drives you only need one IOM module engaged. The throughput I observed so far with scrubbing was good - although something locked up once, I believe my HBA card overheated during the scrub. I needed to power cycle the ds4246 to recover. I turned the fans up on my supermicro chassis, this may have been unnecessary.
It would be helpful if we could pool our knowledge on this device.
It is not the LSI card. It might be those NetApp enclosures but I have hundreds of drives running from LSI cards at work, 124 drives in one server alone, and they just work. You are barking up the wrong tree blaming the controller. The SAS expander in the drive shelf has got to be where the problem is, but even then, it isn't really a problem since the lower speed is still faster than the mechanical speed of the drive.Open to any suggestions on non 2008 and 2308 cards I could try.
This is the chassis I use for my primary home NAS:Chris, You referenced in another post that you are running 2 24 bay backplanes. What make/model?
Thanks

should produce a listing like the one below. If you will share that with us, it might help with the troubleshooting.root@Emily-NAS:~/scripts # sas2flash -c 0 -list LSI Corporation SAS2 Flash Utility Version 16.00.00.00 (2013.03.01) Copyright (c) 2008-2013 LSI Corporation.

Did you try this with a single link to each disk shelf?
Mine case is a little bit different. If drives were hot plugged they are 1.5Gb/s, if they are there on boot they will be 3Gb/s. There is no randomness like what you have seen. Granted that I only got 3 drives for now though.Basically your experiencing the same issue as I am but with the IOM3. I shucked 10 x8TB Elements drives yesterday and plugging them in most of them were at 6Gbps. One I plugged in negotiated to 3Gbps and I reseated it and it went to 6Gbps. Another would only stay at 3Gbps. It's not related to specific slots either as on reboot a different set would go to 3Gbps. Results with the 9207-8e card were significantly worse than with the 9200-8e. The 9200-8e (sas2008) would negotiate about 19/23 drives correctly on reboot. The 9207-8e(sas2308) would only negotiate 8/20 at full speed on reboot.
I think there is something with lsi card/driver in combination with sata drives and this enclosure causing an issue. I have a 9300-8e and a 9305-16e coming to test with and will see if things change with either of those cards. In my case it's not really an issue as the lowest speed (IOM6) is 3Gbps and that is more than enough for the drives I am running. However in your case it is an issue as the drives are capable of faster than 1.5Gbps. An option for you would be to the the IOM6 controllers. They work with the DS4243 chassis and can usually be had on ebay for cheap.
Will keep this thread up to date.

What's interesting is that it is always halving the max speed. I wonder if it was because it tried to multi-path the SATA or something like that. It would be interesting to see if you put 4 IOM6 into one shelf and speed goes down to 1.5Gb/s...
I have 24 of them, but they have their own problems. The LSI chip ones would not work with SSDs for some reason, you can see the drive, SN and so forth, but it shows up as 0B capacity. The other one just plainly don't work. I spent weeks trying to troubleshoot the problem. The seller even send me a Dell H200E and a SSD they tried and worked, but somehow it didn't on mine. It was not even NetAPP because I got a 9211-8i in my desktop with SAS breakout cable and if I put the interposer between the SSD would become 0B in size.Mine were also all negotiating all fine with a small number of drives like 3. Put in 20 drives and I bet your results will be more like mine.
You can't multi-path the sata without using sata interposers in the trays. I don't have any of those (yet) to test with.
