January 29, 20206 yr Author The seller of controllers had the needed quantities of these two: https://www.ebay.com/itm/Genuine-LSI-6Gbps-SAS-HBA-LSI-9211-8i-9201-8i-P20-IT-Mode-ZFS-FreeNAS-unRAID/163846248833 https://www.ebay.com/itm/HP-H220-6Gbps-SAS-PCI-E-3-0-HBA-LSI-9207-8i-P20-IT-Mode-for-ZFS-FreeNAS-unRAID/162862201664 Which of these two models would you all recommend I buy ? Kind regards, Kjetil
January 29, 20206 yr Community Expert Main difference between is that 9207 supports PCIe 3.0, since your board is PCIe 2.0 they will work the same, and like mentioned for normal HDDs 9211 is more than enough, unless using a SAS expander which is not the case, so unless you're thinking on some future upgrade I would go with the cheaper 9211.
January 29, 20206 yr Author Thanks for the feedback. So I guess I will order these. When it comes to switching these out, will the server understand which drive is which after change of controllers ? Or do I need to write down the serial number of each drive and tell the server manually which drive is which ?
January 29, 20206 yr Community Expert Devices are tracked by serial number, you just need to replace the controller and power back on.
January 29, 20206 yr Author Sounds good Do I need new cables, or are the cables and connections the same ?
January 29, 20206 yr You also need SAS to Sata cables (SFF-8087). And you should flash the controllers to the latest firmware in it mode. I also flashed mine without the bios to speed boot times a little bit. And it is also good to attach a small 40mm fan to the heatsink to keep things cool. Edited January 29, 20206 yr by RedReddington
January 29, 20206 yr Author Am I not using SAS to Sata cables now on the SASLP controllers ? I have no idea how to update firmware, should I ask the seller about this ? What exactly should I ask him ? There are some info in the ebay add, but I dont understand much about it: https://www.ebay.com/itm/Genuine-LSI-6Gbps-SAS-HBA-LSI-9211-8i-9201-8i-P20-IT-Mode-ZFS-FreeNAS-unRAID/163846248833
January 29, 20206 yr These cards from this Ebay seller are pre flashed with it-mode firmware and ready to go. Cooling the cards is importent if there is no airflow in your case. Edited January 29, 20206 yr by rl2664
January 29, 20206 yr Author The server has ample cooling with fans, so that should be ok. Does not feel hot inside. But just wanted to clarify about cables, so I need to buy new cables ? The cables for SASLP, are they not also SAS to Sata cables ?
January 29, 20206 yr I also have lots of airflow in my case, but the card still ran very hot. If your saslp card also has the sff-8087 connector, then you can keep the cables. You could ask the ebay seller to flash the card without the bios. You only need that, if you want to boot from the sas controller, otherwise it is useless in my opinion.

January 29, 20206 yr Author From what I can see I have these controllers, are they sff-8087 ? https://www.supermicro.com/en/products/accessories/addon/AOC-SASLP-MV8.php Add a few photos too here...
January 29, 20206 yr Author Reading a bit more - yes it seems they are SFF 8087 - which is great as the cables would be quite a work to exchange. It would have required me to disassemble most of the server... Edited January 29, 20206 yr by Kjetil
February 20, 20206 yr Author Hi again. Finally new controllers have arrived and I have installed them (9211i). The server is turned on, and up and running. But I have not started the array yet. How shall we proceed to start fixing the parity problem and the disc error ?
February 20, 20206 yr Community Expert If the status is the same as last screenshot you need to re-enable both disks, you can do both at the same time: https://wiki.unraid.net/Troubleshooting#Re-enable_the_drive
February 20, 20206 yr Community Expert Damn! You're using 5 LSI controllers! 😛 Everything looks fine so far, all are in IT mode and using latest firmware, no errors for now, make sure there's some airflow on the controllers, especially if they are stacked together, and some must be for so many.
February 20, 20206 yr Author All 5 cards are all close together, so there is not much I can do about that. Fans are running so not sure what more I can do ? Should I do a smart test of the discs before I proceed ?
February 20, 20206 yr Community Expert I don't know what type o case you're using but as long as there's some airflow around them it should be fine, e.g. server cases usually have fans at the front for fresh air intake and then at the back for exhaust, that's enough to create some airflow, depending on the fans used and speed they rotate. 15 minutes ago, Kjetil said: Should I do a smart test of the discs before I proceed ? Seems unnecessary to me in this case.
February 20, 20206 yr Author Ok, so what do I do next ? Do I rebuild both drives with error at once ? It would be great with a step to step description, so I dont do anything wrong at this point
February 20, 20206 yr Community Expert -Unassign both disabled disks -Start array -Stop array -Re-assign both disks (to their original slots) -Start array to begin parity sync/data rebuild If there are any issues grab diags before rebooting or shutting down.
