HW RAID disks seen separately by TrueNAS

[Axl_fzetafs]

I have a 24x bays SuperMicro with mixed SATA disks.
I would like to reserve two disks for the system (the rest for the data) and I connected them to the built-in LSI controller of the X8ST3-F.
I wanted to go for one device manafged by the LSI controller and in the controller BIOS I did created the virtual device.

While installing 13.0-U3.1, I do not see such device but rather the two seprate units, this is totally irrational to me.
Anyway I tried to use those two disks for the boot system and I told the installed I wanted the SWAP.
Later in the procedure the installation stops saying it can find such device.

I know that without any logs/images is difficult to troubleshoto but I wonder if it is possible that I create a virtual device in the builtin LSI and then TRueNAS sees the two disks separately.

TIA, Alex

TrueNAS uses ZFS and ZFS shouldn't be used with HW raid controllers: https://openzfs.github.io/openzfs-d...uning/Hardware.html#hardware-raid-controllers

TrueNAS it is best to have direct access to disks, so passthru the controller directly and manage the disks as individual drives, you can merge them to one mirrored pool inside TrueNAS.

Thanks @Dunuin, @chrcoluk .
I'm speaking of the system disks, not data disks. I encountered problems in creating SW raid for the system disk and hence I went for HW RAID disk, but it is not seen by TrueNAS. The question is about the boot disk.

Do we talk about a TrueNAS-VM or a TrueNAS bare-metal installation?
For the latter, you might be better off posting on the official TrueNAS forum.
For the former, you should give more informations how exactly your whole setup (PVE and TrueNAS) looks like. E.g.: How is what to what connected and the VM-config (qm config VMID) would be a good start.

I encountered problems in creating SW raid for the system disk

What problems? vdisks from and managed by PVE or passthrough? If passthrough, which exactly?
TrueNAS uses also ZFS for its boot disk(s). So for these you should also not use any kind of hardware raid/controller.
If you have problems (on TrueNAS) with creating a software raid (ZFS in this case), you should check your hardware(-settings) and your whole setup (read: how you have things set up).
But to help here, as I said, more informations are needed...

@Neobin , facepalm for me . I definitely wrote on the wrong forum... it's TrueNAS baremetal installation.
Sorry for that , and stupid me: I wasted my time instead of going for the right support
