ServeRAID M5210e passthroughand syspd corruption

[Steven Hartland]

mfi is a raid card it doesn't really have a true passthrough mfisyspd is
the best you'll get. I'd recommend you switch to an HBA card which uses
mps driver instead.

When you said you're seeing mfisyspd corruption what specifically are
you seeing?

    Regards
