Hmmm, maybe you have the same problem I have with the LSI-1064E .
I was able to see a disk though, even though the RAID did not come up.
I had to enable the port otherwise the IOC page 2 did not indicate max
disks of non-zero, and also not valid RAID info.
It also did not help when I executed (enabled the port) afterwards ...
strange, you might ask Matthew's opinion on this , I just recently
ported his driver to FreeBSD 2.2.X (including required CAM code) for a
project I am working on, I did not develop it.
In the file mpt.c (location /usr/src/sys/dev/mpt/mpt.c) I had to make a
change to enable the port, otherwise the RAID will not get probed
because the pages do not contain valid info.
Go to function mpt_enable_ioc.
Scroll down until you see this snippet:
------------------------- snippet
----------------------------------------
/*
* Enable the port if asked. This is only done if we're
resetting
* the IOC after initial startup.
*/
//if (portenable) {
if (1) {
/*
* Enable asynchronous event reporting
*/
//jjk moved it down a bit ?
//mpt_send_event_request(mpt, 1);
if (mpt_send_port_enable(mpt, 0) !=3D MPT_OK) {
printf("failed to enable port 0\n");
return (ENXIO);
}
mpt_send_event_request(mpt, 1); //jjkhack=20
}
return (MPT_OK);
-------------------------- snippet
---------------------------------------
Change from:
if (portenable) {
change to:
if (1) {
You will se I moved down the mpt_send_event_request, but you do not need
to do that.

I described in my first message, that RAID was setup in BIOS, but
FreeBSD can't see it's raid. It is main problem! ...not "event 0x16"
problem
Once again:
---
In system BIOS I set
Mass storage controllers menu
SAS controller - Enable
SAS configure as SW RAID - Enable
RAID was build in controller's BIOS (CTRL+E during boot).
---
We talking about Intel 5000PAL + SAS backplane
There is LSISAS1054E chip and 3 SAS Ports 1U Active Backplane and Intel
Embedded Server Raid
Technology II for RAID setup (CTRL+E during boot)
FreeBSD can't see raid
