Embedded / PCI HBA LSI RAID monitoring utility for Linux / RHEL on Sun hardware (eg. x4200)?

We're kickstarting RHEL on a number of Sun x4NNN systems --
x4100/x4200/m2/x4150 etc. and soon likely x4170m2.  I've not been able to find
a good CLI tool to monitor the state of HBA/hardware mirror volumes.  Under
Solaris we grudgingly use raidctl for this purpose.  lsiutil seems to be able
to see these HBA's on at least some systems, but doesn't seem to provide a
convenient way to check for failed disks via script.

I need to either identify a usable tool, or figure out the Linux MD system.
Ohhhhhh how I miss ZFS.

One advantage of the HBA mirroring approach is avoiding the hassle of BIOS
boot devices if the primary mirror disk were to frotz.

Thanks for any experiences here that can be shared.  Sun seems to distribute a
graphical tool, which obviously isn't suitable.
