P410i /dev/sg0 report error when enabling HBA mode #7

Hi,

I tried to use this tool on Smart Array P410i, to enable its HBA mode, and here is my environment:
HP DL380 Gen7 server,
Ubuntu 18.04 LTS HWE, installed on a SATA SSD connected to system via the SATA port for the optical drive, which should be bypassing the P410i card.
Kernel 5.3.0-53-generic

Before running "hpsahba -E", I have three relevant devices which are /dev/sg0, /dev/sg1 and /dev/sg2.

I was able to run "hpsahba -E /dev/sg1" without any error, but when I run "hpsahba -E /dev/sg0", the system gave the following error:
FATAL ERROR: /dev/sg0: ioctl(CCISS_PASSTHRU) failed with command BMIC_IDENTIFY_CONTROLLER, rc == -1: 25 Inappropriate ioctl for device
After running this, no changes are observed on the output of lsblk and the number of sgX device under /dev/

After running "hpsahba -E /dev/sg1, I noticed that two hard disks that connected to the P410i has gone from the output of lsblk command. And the sg2 device has gone under /dev/ folder.

I enabled hpsa.hpsa_use_nvram_hba_flag=1 in grub, and hpsa module is showing up in lsmod output.

What I did not do is patching the kernel patches that you provided. If the issue is with the kernel patch, could you advise how should the patching by done in my case?

Best Regards,
Terry YIN

You need to patch the kernel for it to work. I have created a branch with DKMS support that allows for simpler patching of hpsa driver https://github.com/artizirk/hpsahba/tree/dkms/kernel/dkms
It should work with 5.4 kernel in Ubuntu 20.04, don't know about other versions.

Hi Artizirk,

Thanks a lot for the help, and I just tested it and it works after some tweaking for my system.

As spoken, my system is Ubuntu 18.04 LTS HWE, so I first upgrade kernel to version 5.4.0-050400.

And because the location of the kernel source file for Ubuntu is /lib/modules/ rather than /usr/lib/modules/, so I adapt your KDIR variable in your Makefile accordingly.

One issue that I noticed is that it does not stay effective across reboot. Everytime I reboot the system, I have to "modprobe hpsa" again, otherwise there will be no RAID card connected drives showing up in lsblk. I'm pretty sure that the updated HPSA modules are automatically loaded after rebooting, but I still need to modprobe it again. Have you seen anything similar on your side?

Regards,
Terry

Old driver is probably loaded in initramfs and needs a rebuild, you may also need to add the module option to /etc/modprobe.d folder.

I actually did update initramfs using update-initramfs after loading dkms modules. I also checked dmesg output but did not find any outstanding error.

I kind of checked & tried a few different methods, however, without knowing what happened, in one of my attempts, it suddenly works. I mean the bare drives could be exposed to OS now even across reboot. I'm still trying to figure out what happened here and will shall it out when it's confirmed.

Still waiting an answer from experts.
My ubuntu version is 20.xx desktop I rolled back the kernel to 5.4xxx from 5.8 and patched again with kernel headers and repeated all the steps but no luck in HPSAHBA -i I get the Hba Enabled and working, but no disks attached showing in lsblk, any clue or help what wrong I am doing ? thanks
