Before changing this default driver selection policy, LSI advises users to understand how the driver selection policy works. Now what I get: Skip site navigation 1 Skip section navigation 2 Header And Logo. Last modified 15 months ago. The mfi 4 driver does not understand the cam 4 layer and it directly associates storage disks to the block layer. Do we need any modifications to mrsas 4 in order to support the syntax like:

Ok, i got access to such hw one of my BSD servers works with a such controller and will try to work on this. Want to link to this manual page?
Powered by Trac 1. Dear chrfrankethank you much for your responsive reaction. Opened 2 years ago.
Need to find some time to play with dtrace and find the problem As usual – help lis wanted. The mfi 4 driver does not understand the rreebsd 4 layer and it directly associates storage disks to the block layer. I badly need to monitor S. Show comments Show property changes. See TracTickets for help on using tickets.
LSI’s policy is to provide priority to the mfi 4 driver to detect MR-Fusion cards, but allow for the ability to choose the mrsas driver to detect MR-Fusion cards.
Now server reboots on issuing identify command.

I will attach my patch to this ticket. Although multiple switching is possible, it is not recommended. I have smartctl 6. Switching drivers is designed to happen only one time. To continue, add one or more ‘-T permissive’ options.
Whom shall I ask for details?
If someone interesting to see progress on this ticket – please provide ffeebsd ssh access to hardware: TODO The driver does not support big-endian architectures at this time.
The user may see different device names when switching from mfi 4 to mrsas.
This behavior is Functions As Designed and the user needs to change the fstab 5 entry manually if they are doing any experiments with mfi 4 and mrsas interoperability. The following bits have the described effects: Best think is to implement smth freesd mrsasp which exports drives.
LSI recommends setting hw. From what i see – adding megaraid or mrsas? Oldest first Freebwd first Threaded. I think i can implement megaraid-like functionality if someone will provide me access to such hw.
There is no -d megaraid,N device type in the FreeBSD version of smartmontools because in the past it worked with the mfip. Recommended and supported driver for this newer controller is mrsas 4 and old mfi 4 driver is neither supported by LSI nor actively developed, it supports new controllers in some obsolete ineffective way. There is a native ioctl interface defined here: To change the firmware fault check timer value for a specific mrsas driver instance, set the following tunable value in loader.
