Summary0000904: CCISS kmod module not working with CENTOS 7.6, kernel 3.10.0-957.1.3
DescriptionHi,

I am using DL360p Gen8,

Running CENTOS 7.6,

kernel version: 3.10.0-957.1.3.el7.x86_64.
 
The kernel boots up with hpsa module by default.
Instead of hpsa driver I want to try use cciss driver module.
But the booting is failing with error "couldn`t find root partitions".
I have attached the screenshot of the booting error(Error Boot.png).
I have added cciss.ko.xz as a part of initramfs.
I have attached the screenshots of grub.cfg file which comes along with standard OS installation with hpsa as a module (Dracut-hpsa.png)
I have attached the screenshots of modified grub.cfg file to use cciss driver at the time of booting (Dracut-cciss.png).

I am looking for help to boot up linux kernel using cciss driver.

If any solution to resolve this booting issue will be a great help.

Thanks in Advance!!

Will you try installing kernel-lt and see if that works for your hardware?

As per your suggestion I have installed the kernel-package from the link shared- http://elrepo.org/tiki/kernel-lt

It has been observed that the hpsa.ko and cciss.ko files gets copied when we installed the kernel-package.

We have also observed that the initramfs has entry for hpsa.ko.

After rebooting the system gets booted with the newly installed kernel and hpsa.ko driver.(with-hpsa.txt)

I have done some changes so that system can boot up with cciss driver.I have used attached dracut.conf to create new initramfs with entry for cciss.ko (no hpsa.ko in initramfs).

But the system failed to boot up when I rebooted the system.

Please find the attached file for booting error (booting-error-cciss.PNG).

I think I am missing out some setting in grub.cfg or kernel boot-time parameters specific to cciss.ko driver.

I have also attached grub.cfg and dracut.conf for your reference.

If you need any more information please let me know.

It will be great if you can help me to resolve this booting issue with cciss.ko driver.
