[ILUG] Monitoring of LSI Logic Megaraid controller

Heinz Mauelshagen's dmraid is useful only for (supported) fakeraid
(manufacturer-specific software RAID with BIOS assist) host adapter:
It fills the same role for 2.6 kernels that ataraid did for 2.4.  As you
noted in your original post, the dmraid documentation mentions that it
supports an LSI Logic  MegaRAID flavour of software RAID set, in
addition to the expected Adaptec HostRAID, SiI Medley, Intel ISWRAID,
etc.

As _I_ noted in my earlier comment, I'm familiar with the MegaRAID name
as a line of genuine RAID chipsets, this newer fakeraid variant being
news to me.  

It's certainly possible that your unspecified LSI Logic
MegaRAID-equipped board is indeed genuine hardware RAID, but that would
make your exploration of dmraid, and inquiry into its specifics,
irrelevant and an unfortunate waste of time, since it works with (most
varieties of) fakeraid stripe sets, only.

I hope it works out for you, anyway.
