Linux on Marvell 88SE9230. How to get stats?

I use Marvell 88SE9230 controller on my home Linux server. HP does have utility to setup raid and get some stats. But I'm wondering how to get any status from a Linux system. Quick googling shows only Linux drivers for accessing array itself on previous versions of kernel, but I want to know SMART status of drives. Smartctl doesn't work: root@iris:~# smartctl -a -d marvell -T verypermissive /dev/sda smartctl 7.1 2019-12-30 r5022 [x86_64-linux-5.4.0-96-generic] (local build) Copyright (C) 2002-19, Bruce Allen, Christian Franke, www.smartmontools.org Read Device Identity failed: Unknown error === START OF INFORMATION SECTION === Device Model: [No Information Found] Serial Number: [No Information Found] Firmware Version: [No Information Found] Device is: Not in smartctl database [for details use: -P showall] ATA Version is: [No Information Found] Local Time is: Thu Jan 27 19:11:54 2022 MSK SMART support is: Ambiguous - ATA IDENTIFY DEVICE words 82-83 don't show if SMART supported.
