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 /var/log/*. 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 /var/log*. I then replaced the drive and the RAID control re-synchronized the drives correctly. So, my question is: How can I get messages from the RAID controller that there is a drive failure in the RAID system?

We are considering the purchase of a DELL 2950 Power Edge server.
Does anyone have any experience getting the PERC5/i RAID controller working with Crux2.3?
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 [1], so if you happen to get one of these, try to update the firmware version, or follow this workaround [2].
