Why is TCRP "generating fake SMART data?"

[Autastic]

Latest TCRP, tried on two different boards, one of which has been running DSM6 on Jun's loader for five years with SMART working properly. Disks are WD Reds connected to an LSI 9211-8i controller flashed to IT mode, the same card and drives used in the DSM6 NAS. lspci says it’s an “LSI SAS2008” controller though. This hardware has been producing non-fake SMART data all along, but now all my data is fake. How do I get my non-fake SMART capability back?

Wrong HBA model number

A 'google' of the command 0xd0 (uncorrected read errors?) shows up some results that might help you diagnose;

I'm not an expert but I wonder if there is a difference between smart reporting modules between DSM6 and 7 due to kernels? and or the hba firmware/modules? You might want to look for any firmware updates to the HBA at broadcom if your firmware is 'old'  https://www.broadcom.com/support/download-search

So upgrading DSM from 6 to 7 caused my BIOS to change settings and cause SMART reporting to fail?

I would not say 'update caused bios to change settings', but lets imagine the hba bios, dsm6 kernel and modules were all 'mutually compatible' with correct smart data being shown in v6. update to v7 has somehow 'broken' this, be it the kernel, driver module or hba bios. you may need to get them 'back in sync' and if this was my setup i'd look to update the hba bios, if it is not the latest. I had a problem a while ago with a marvell sas hba not seeing correct drive size/type/features. updated the hba bios and it fixed it.
