Hi,
I have a Dell PowerEdge 2850 that was running Debian with a 2.4 kernel.
I have just upgraded it to 2.6.26 and as part of that upgrade also begun
using udev. I am unsure whether this is a udev problem or a kernel
problem.
With 2.4 I used to have a block device "megadev" in /proc/devices which
the Dell/LSI scripts use to communicate with the PERC. However, since
the upgrade I have no block device and udev is not creating
/dev/megadev0.
The array is functioning fine. Would anyone be able to offer any
suggestions about how to get /dev/megadev0 back so I can use the
monitoring tools again? Some potentially useful output below.
Thanks,
Chris
