I was able to resolve this with info found at the following two links: [URL] lists.us.dell.com/.../043896.html I'm using megactl after running 'mknod /dev/megadev0 c 10 57' and all is well.
Hello, I'm ripping my hair out now. I've been trying for the past week to get a simple monitoring solution in place for an older PE 1850 that has Perc4 RAID. I realize that OMSA is out of the picture, after going back as far as 5.5 with i386 versions and having no success. I've also tried mpt-status, raidmon2, raidmon, megarc and megamon, with no luck. I have not tried Nagios yet. I'm hoping that I'll reach someone here who is familiar with the exact problem kernel releases after (I think) 2.6.24 have with all of these tools. I'm happy to PayPal $100 to the person who can get RAID monitoring setup on this server.
PE 1850 / Monitor Perc4 / Centos 6.4 (x86_64) / $$$
