The kernel can see the drives, and I am able work with /dev/sda and /dev/sdb
(the logical drives under the RAID controller) right of the Crux 2.3 CD
Here is the problem that I currently have: I want to monitor the health of
the RAID arrays. After booting the system, I removed one of the drives from
the Array. I was expecting to see an entry in /var/log/messages.
The RAID controller handled the loss of a physical drive correctly (the
logical drive was still accessible), but no messages were logged in
I then rebooted. When the system initiated the RAID controller, the
controller stated that the logical drive has been degraded. This is what I
expected to see...but that same message does not appear in dmesg or
I then replaced the drive and the RAID control re-synchronized the drives
So, my question is: How can I get messages from the RAID controller that
there is a drive failure in the RAID system?

For this controller you'll have to enable CONFIG_MEGARAID_SAS in the kernel.
There seems to be a DMA bug with firmware versions less than *-0095 , so
you happen to get one of these, try to update the firmware version, or
this workaround .
