SCSI drives not listed in /dev/


Goal:
Take 3 SCSI hard drives, connect them to a PCI SCSI controller (Startech.com pciscsiuw), create software RAID 5 array.

Current State:
The drives are instaled, and the SCSI controller appears to be functioning properly.

lspci shows the SCSI controller like this:

# lspci -vv -s 00:08.0
00:08.0 SCSI storage controller: Initio Corporation 360P (rev 02)
Subsystem: Unknown device 9292:0202
Control: I/O+ Mem+ BusMaster+ SpecCycle- MemWINV- VGASnoop- ParErr- Stepping- SERR- FastB2B-
Status: Cap- 66MHz- UDF- FastB2B- ParErr- DEVSEL=medium >TAbort- <TAbort- <MAbort- >SERR- <PERR-
Latency: 32, Cache Line Size 08
Interrupt: pin A routed to IRQ 11
Region 0: I/O ports at e000 [size=256]
Region 1: Memory at df000000 (32-bit, non-prefetchable) [size=4K]
[virtual] Expansion ROM at 40020000 [disabled] [size=32K]


No SCSI devices are listed:
# ls /dev/sd*
ls: /dev/sd*: No such file or directory

lsmod does not show sd_mod or scsi_mod unless modprobe sd_mod is run, then they show up:
# lsmod |grep sd_mod
sd_mod 20545 0
scsi_mod 136169 1 sd_mod

I believe I have compiled enough SCSI support into the kernel using make menuconfig, but I'm not enirely certain.

What am I missing? Help is appreciated in advance.

Is the SCSI controller module loading? Check the output of lsmod, it should be initio or was it compiled into the kernel?

initio was not loaded, running "# modprobe initio" has corrected the issue. It has also started sd_mod and scsi_mod. After the systemd reboots, the changes are lost. How do I make the modprobe command auomatically execute?

Also, when I go to make the RAID 5 array, is this the proper command?:
# mdadm --create --level=5 --raid-devices=3 /dev/md0 /dev/sda /dev/sdb /dev/sdc

Do I have to do anything special to format /dev/md0?

Thanks a lot!
