There is no -d megaraid,N device type in the FreeBSD version of smartmontools because in the past it worked with the mfip. See TracTickets for help on using tickets. 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. From what i see – adding megaraid or mrsas? Now what I get:

With the above design in place, the mfi 4 driver will attach to a MR-Fusion card given that it has a higher priority than mrsas. Before changing this default driver selection policy, LSI advises users to understand how the driver selection policy works. Want to link to this manual page?
mfi driver performance too bad on LSI MegaRAID SAS i
The user may see different device names when switching from mfi 4 to mrsas. The mfi 4 driver does not understand the cam 4 layer and it directly associates storage disks to the block layer.
Ok, i got access to such hw one of my BSD servers works with a such controller and will try to work on this. Whom shall I ask for details? Skip site navigation ,si Skip section navigation 2 Header And Logo.

Can anything be done about this? The following bits have the described effects: FreeBSD has a cam 4 layer which attaches storage devices and provides a common access mechanism to storage controllers and attached devices. 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.

Dear chrfrankethank you much for your responsive reaction.
TODO The driver does not support big-endian architectures at this time. Do we need any modifications to mrsas 4 in order to support the syntax like: Oldest first Newest first Threaded. To change the firmware fault check timer value for a specific mrsas driver instance, set the following tunable value in loader. Need to find some time to play with dtrace and find the problem As usual – help is wanted.
LSI recommends setting hw. For those customers who are using a MR-Fusion controller for the first time, LSI recommends using the mrsas driver and setting hw. See TracTickets for help on using tickets.
Powered by Trac 1. I will attach my patch to this ticket. There is a native ioctl interface defined here: Now server reboots on issuing identify command. From what i see – adding megaraid or mrsas? To continue, add one or more ‘-T permissive’ options.
Recommended and supported driver for this newer controller freebsdd mrsas 4 and old mfi 4 freebsd is neither supported by LSI nor actively developed, it supports new controllers in some obsolete ineffective way. By default, the mfi 4 driver will detect these controllers. Last modified 15 months ago. 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.
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 lssi. I badly need to monitor S.
