Halo,

is there a way to get work LSI HBA in Linux VM on Truenas
I have a system with Supermicro A2SDi-H-TF board and Broadcom/LSI SAS1068E PCI-Express inside.
I use Truenas 12.2-RELEASE-p6 FreeBSD 12.2-RELEASE-p6.

I would like to use LTO drives in Linux Mint for backup.
pciconf -v -l shows:


mpt0@pci0:2:0:0: class=0x010000 card=0x03961014 chip=0x00581000 rev=0x08 hdr=0x00
vendor = 'Broadcom / LSI'
device = 'SAS1068E PCI-Express Fusion-MPT SAS'
class = mass storage
subclass = SCSI

Which steps (tunables) could I ad and which parameters within.

I found some hints in internet to get graphical interface or USB devices but they did not help me.

Maybe has anyone an idea.

You will need these loader tunables:
Code:
vmm_load="YES"
pptdevs="2/0/0"


After a reboot you should be able to configure the device in the UI.

Halo,

thank you for your help. I can see the device in vm list.
But there is an another problem - when I try to add the passthrough device the circle does not stop and after maybe 15 minutes the truenas crashes.
