It is known that the driver is closed source and is not included in Ubuntu.Īs far as we can see, these drivers are supported on SUSE and Redhat. The Ubuntu 12.04 certification was completed in SATA mode only for the HP D元20e Gen8 servers. The additional drivers for RAID controllers are usually for enabling some utilities to access additional data (that is not required in disk access).The current HP Dynamic Smart Array B110i/B120i/B320i controller driver for Ubuntu 12.04 does not work when configured as a RAID device with 2 or more disks. A boot from other array types requires that the fake/hardware RAID does enough to point the BIOS/UEFI to correct spot. Hence one can boot from (some) RAID arrays in both RAID and AHCI modes. If it is at the end, then for RAID1 (and presumbaly JBOD) the beginning of drive looks like regular non-raid volume the partition table and filesystem in first partition do start “as usual”. All RAID, (even fake,) do write metadata onto the drives. On boot the BIOS/UEFI read disk without being aware of any RAID. Was there only “Disable” and no “Enabled, AHCI” there? Since it is the only controller, you cannot disable it. In AHCI mode the controller is plain SATA controller. Typically, on consumer boards (and I’m pretty sure that also on HPE), the BIOS (or UEFI on recent generations) does have at least two modes on those controllers: AHCI and RAID. Websearch with “8086:1c04” finds “B110i”, so HPE has made more than one “setup” from the “C200 Series Desktop SATA”. Rocky has driver for it, the “ahci”.Īpparently some OEM’s (like HPE and Dell) do tag some devices and hence the “Subsystem” info. The device ID is 8086:1c04 (with “8086” meaning Intel) – an Intel SATA Controller. I want to know if in this setup I would, for example, still be able to move the disks to a different system (without any RAID controller) and access the data. So my question is, is it acceptable to use these disks in this configuration and use OS based software RAID? My main concern is reliability, perfomance is not important. In this configuration the 4 data disks still show up as /dev/sd* devices. The only way to get the system to boot is to add the SSD as a single volume to a virtual disk in the RAID configuration, for which I obviously need to enable the controller. However, when I disable the controller in the BIOS all disks are shown during the boot sequence, but the system no longer boots from the SSD. Moreover, many people recommend to not use the controller and use OS based Software RAID (mdadm) instead. This type of controller is referred to online as a FakeRAID controller, and it requires an OS driver (hpvsa) which does not appear to be available for RHEL8. The system boots from an SSD, and there are 4 identical disks for storage which I would like to configure in a RAID. I am running Rocky Linux 8 on a HP Proliant MicroServer gen8 which contains a HP Dynamic Smart Array B120i RAID controller.
