.
| Code: | ~ # lspci -nn | grep RAID

|
| Code: | ~ # cat /proc/devices
Character devices:
1 mem
4 /dev/vc/0
4 tty
4 ttyS
5 /dev/tty
5 /dev/console
5 /dev/ptmx
7 vcs

I have installed necessary kernel modules, gentoo packages and LSI software megactl-0.4.1 http://hwraid.le-vert.net/wiki/LSIMegaRAID#a3.4.Aboutdevmegadev0 for usage and monitoring the controller:
| Code: |

and megactl, megarpt commands not give me any output:
| Quote: |
~ # /root/megactl-0.4.1/megactl
~ # /root/megactl-0.4.1/megarpt
|
the device /dev/megraid0 seems to be 0
| Code: | ~ # ls -lah /dev/ | grep mega
crw-r--r-- 1 root root 252, 0 Aug 21 15:58 megadev0
cr-------- 1 root root 251, 0 Mar 20 19:57 megaraid_sas_ioctl_node |
after some internet research i have tried with command:
| Code: | | mknod /dev/megadev0 c `cat /proc/devices | gawk '/megadev/{print$1}'` 0 2>/dev/null |
without any changes.
Anyone can help me? any suggestion is appreciated, thanks in advance,
regards Maurizio

pigreco,
Do you have kernel support for the LSI Megaraid?
Is it built an a module but not loaded?
