I downloaded kernel source from https://github.com/torvalds/linux.git extracted the drivers/scsi/aacraid/ and recompiled it with dkms this new module now see the card... it bugs, I guess 'cause I "force-compiled-it" (I had to add -Wno-incompatible-pointer-types and I had to comment out part of the source as /var/lib/dkms/aacraid/1.2.2/build//linit.c:1480:14: error: initialization of ‘int (*)(struct scsi_device *, int, void *)’ from incompatible pointer type ‘int (*)(struct scsi_device *, unsigned int, void *)’ [-Werror=incompatible-pointer-types] .ioctl = aac_ioctl, ^~~~~~~~~ /var/lib/dkms/aacraid/1.2.2/build//linit.c:1480:14: note: (near initialization for ‘aac_driver_template.ioctl’) /var/lib/dkms/aacraid/1.2.2/build//linit.c:1482:20: error: initialization of ‘int (*)(struct scsi_device *, int, void *)’ from incompatible pointer type ‘int (*)(struct scsi_device *, unsigned int, void *)’ [-Werror=incompatible-pointer-types] .compat_ioctl = aac_ioctl, ^~~~~~~~~ /var/lib/dkms/aacraid/1.2.2/build//linit.c:1482:20: note: (near initialization for ‘aac_driver_template.compat_ioctl’) /var/lib/dkms/aacraid/1.2.2/build//linit.c: In function ‘aac_probe_one’: /var/lib/dkms/aacraid/1.2.2/build//linit.c:1730:8: error: ‘struct Scsi_Host’ has no member named ‘max_segment_size’ shost->max_segment_size = shost->max_sectors << 9; ^~ /var/lib/dkms/aacraid/1.2.2/build//linit.c:1732:8: error: ‘struct Scsi_Host’ has no member named ‘max_segment_size’ shost->max_segment_size = 65536; ^~ so I just got it to compile to see if it will see the card, and it does... so there is def. something wrong with the aacraid module that comes with centos 8 ( 4.18.0-301.1.el8.x86_64 is running attm) |

You can test the latest in-kernel driver by installing kernel-ml from ELRepo. I see: filename: /usr/lib/modules/5.11.16-1.el8.elrepo.x86_64/kernel/drivers/scsi/aacraid/aacraid.ko.xz version: 1.2.1[50983]-custom license: GPL description: Dell PERC2, 2/Si, 3/Si, 3/Di, Adaptec Advanced Raid Products, HP NetRAID-4M, IBM ServeRAID & ICP SCSI driver |

@toracat don't I need kernel 5.11 to load them ? never used this kernel-ml package, how to load the driver from /usr/lib/modules/5.11.16-1.el8.elrepo.x86_64/kernel/drivers/scsi/aacraid/aacraid.ko.xz instead a default location /lib/modules/4.18.0-301.1.el8.x86_64/kernel/drivers/scsi/aacraid/aacraid.ko.xz ? thanks |

installed kernel-ml from elrepo new driver works (shows the same version but "modinfo aacraid" shows it's loading it from the 5.11.16-1 tree) no clue how kernel/modprobe now decides what driver to load, will have to check that out (will appreciate link to some doc if you have one to share) but this works :) thanks |

@arhi In the RHEL/CentOS kernel, many device IDs have been removed from the aacraid driver. Your device [9005:0285] must be one of them. This is why the driver in the upstream (kernel.org) kernel works. The best solution for you is to use ELRepo's kmod-aacraid package. There, the ones removed from the distro kernel have been added back. So please give it a try. |

@toracat, yes, elrepo kmod works, thanks |

@arhi That is great to hear. Now closing as 'resolved'. If you have any question regarding the kmod, you can go to ELRepo's venues (mailing list or bug tracker). |
