How to switch HBA driver?

[ejprice]

Greetings everyone!

We're running OpnSense on a Dell T340 with a PERC H730 controller. OpenSense is giving some hardware errors with the mfi driver.

Code: [Select]

mfi0: I/O error, cmd=0xfffffe00d9307540, status=0x3c, scsi_status=0
mfi0: sense error 0, sense_key 0, asc 0, ascq 0
On the 21.7, fixing it was as simple as adding mrsas_load="YES" to the /boot/loader.conf.local file and that resolved the issue.

The file still exists on the system after a command line upgrade to 22.1 - HOWEVER, FreeBSD/OpnSense is back to loading the mfi driver, causing the above error.

Code: [Select]

Does anyone know how to force the loading of the mrsas driver over the mfi driver?

Thanks in advance!
