But I see only 3: Samudrala Prasad 54 2. By default, the mfi 4 driver will detect these controllers. FreeBSD has a cam 4 layer which attaches storage devices and provides a common access mechanism to storage controllers and attached devices.
This way we can utilise all the disks The mfi 4 driver does not understand the cam 4 layer and it directly associates storage disks to the block layer. LSI recommends setting hw.

The following bits have the described effects: Before changing this default driver selection policy, LSI advises users to understand how the driver selection policy works. Changing the default behavior is well tested under most conditions, but unexpected behavior may pop up if more complex and unrealistic operations are executed by switching between the mfi 4 and mrsas drivers for MR-Fusion. Maybe it’s fmi differently, not disable raid but something else?

Switching drivers is designed to happen only one time. The mrsas driver is cam 4 aware and devices associated with mrsas can be seen using camcontrol 8. Raspberry 3, 8 In that way create RAID0 arrays for remaining drives. The user may see different device names when switching from mfi 4 to mrsas. Islam Sabyrgaliyev 12 1 5.
For those customers who are using a MR-Fusion controller for the first time, LSI recommends using the mrsas driver and setting hw. Sign up using Facebook. Although multiple switching is possible, it is not recommended. Home Questions Tags Users Unanswered.
