I actually don't run unRAID. However if it runs a relatively recent version of the Linux kernel I don't see why it wouldn't work. I've found that I need to load the Linux sg module for it work correctly: # modprobe sg It doesn't have very many dependencies. Here is the list of libraries it's linked with: linux-vdso.so.1 (0x00007ffc8d98b000) libdl.so.2 => /lib64/libdl.so.2 (0x00007f5043b5b000) libpthread.so.0 => /lib64/libpthread.so.0 (0x00007f5043b3a000) librt.so.1 => /lib64/librt.so.1 (0x00007f5043b30000) libstdc++.so.6 => /usr/lib64/libstdc++.so.6 (0x00007f504395b000) libm.so.6 => /lib64/libm.so.6 (0x00007f504380f000) libgcc_s.so.1 => /usr/lib64/libgcc_s.so.1 (0x00007f50437f5000) libc.so.6 => /lib64/libc.so.6 (0x00007f5043617000) /lib64/ld-linux-x86-64.so.2 (0x00007f5043b8d000)

The original post states that an HP Service Pack, and thus a license, is required to put the controller into HBA mode. Here is a legal way to do it without requiring the service pack disk. I recently purchased a DL360e GEN8 with a P420 controller from EBAY. Here is the method I used: 1) Install the latest system BIOS. Not strictly necessary for this procedure, but I always prefer to have the latest BIOS on a system before upgrading RAID firmware.

This requires the host to be running a Windows OS for the flash procedure. Since my hypervisor is Linux I installed a small Windows 10 installation for this purpose. You don't need to activate Windows for this purpose. I deleted the Windows partition after upgrading the controller firmware. I couldn't find a method to upgrade the P420 firmware directly from Linux. I'd be interested to hear if that's possible. Link to the P420 firmware install image: https://support.hpe.com/hpsc/swd/public/detail?swItemId=MTX_71b2939cd1d84aada5afece82b 2.1) I have since located a Linux version of the P420 firmware update tool. So no Windows required for updating. Link to the latest firmware: 8.32 https://support.hpe.com/hpsc/swd/public/detail?swItemId=MTX_42b6aa58956a438aa85bd73d0f 3) The ssacli command referenced in the original post can be downloaded separately from HP. Download any Linux live USB image of your choosing. Place the ssacli command on the USB disk. Boot the USB disk and issue the ssacli hbamode= command as stated above.

Did you remove the remove the raid configuration from the physical drives? If the drives were part of a previous raid configuration the controller will detect this state and prevent the OS from accessing the drive. This is a safety measure. The "ssacli" utility can be used to remove the raid config block from physical drives. Here is the associated documentation from the "ssacli" utility: <target> modify [clearconfigdata] In HBA mode, physical drives with RAID configuration data are masked from the operating system. The "clearconfigdata" command clears RAID configuration data and allows the drive to be exposed to the operating system. If a controller is specified as the target, all physical drives on the controller with RAID configuration data will be cleared. Individual physical drives can also be specified. The target can be any valid controller or physical drive which supports this feature.
