mfiutil does not find controller

[oskarn97]

Hey!
I am using LSi-9260-8i which perfectly works with OS X - it also lists up under SAS.
However, I am not able to monitor the controller using mfiutil, I only get
mfiutil: mfi_open: No such file or directory

What can I do?
Thanks!

Hi!
Try sudo mfiutil

Hi,
thanks, yeah I tried that but does not help.
Any idea what else I can do?
Everything but the monitoring works fine.

What is the output of ls -la /dev | grep mfi with kext loaded?

[oskarn97]

Does not return anything. com.apple.driver.SASMegaRAID is loaded.
It is visible in the profiler tough...

Probably Apple changed something related to device creation in macOS. Which OS version do you use?
Other reason may be that I broke something during recent changes. Have you tried old version like https://github.com/dukzcry/osx-goodies/releases/download/1.0/SASMegaRAID.zip?
P.S.: The problem is that I don't use Macs anymore, so can't test things myself. Also I'm out for 4 days. Will continue after that, if you're interested.

I am on OS X 10.13.4 - the old version of both the kext and mfiutil do not work either for monitoring.
Yeah would be great if you could have a look at it again. I can provide you with more details if needed.
Thanks!
Best

Exact same problem on 10.12.6. Tried mfiutil packaged in release 1.2 and the one built using the mfiutil.sh script. The kext loads and works; I've been playing with all sorts of drives on my LSI 9261-8i. There is nothing with mfi in /dev/.

[dukzcry]

Patches are welcome. Unfortunately I can't fix that issue myself, because a) I don't use Macs for quite some time 2) I don't know what Apple has changed since in their OS. It worked in the past.

Its strange that you have nothing with mfi in /dev. Otherwise you could try the following solution.

This is super weird... I have not been collecting kernel logs (may do it afterwards, but since this is an AMD Ryzen Hackintosh I cannot guarantee if those logs are good) but /dev/mfi0 seems to pop up iff I manually load the driver with kextload. Upon accessing it with mfiutil, however, leads to immediate freeze (kernel panic). Tested under 10.15.1 with LSI MegaRAID 9260-8i (IBM ServeRAID M5015 flashed with vanilla firmware).

Edit: I think I got the wrong error report...
