mpt2sas issues

[ladinek]

I have server board Intel S1200V3RP with Xeon E3-1230v3, 32GB RAM, controller LSI SAS 2008 (1000:0072, subsystem [1734:1177] which is Fujitsu, flashed to IT. I was unable to finish the 10.0 TCRP process, but with 9.4.9c WITHOUT update/fullupgrade - just serialgen, identifyusb and realmac, I was able to build DS3622xs+ version 7.1.1-42962 update 1. I have one drive on SATA port and some drives on HBA. The SataPortMap was properly detected as 58, as the board has 5 onboard SATA ports and the HBA is 8-channel.  Everything works fine, until power off. On cold start, BIOS sees all drives as well as those on the HBA, however after boot, only the drive on the onboard SATA is visible. Listing PCI, the device is seen, but no kernel driver associated.

The asterisked line is missing. However, lsmod shows mpt3sas module.

After warm reboot, the mpt3sas driver gets loaded and disks are visible. Minor consequences are that controllers order probably changes due to missing driver, because drives enumeration changes and the SataPortMap is therefore wrong. But this is not the issue for now, I just need fix the stability of the boot process before I will proceed with loading some valuable data. I tried even patch DSM to update 6, which was success without any touching of the loader, but behavior is the same.

Any idea?
