[TriLUG] SATA HD RAID5 Controller for linux

[Mike Seda]

Hi Jason,
I just found out that monitoring is achieved with the utility provided 
below:
http://lsilogic.com/files/support/rsa/utilities/megaconf/ut_linux_megarc_1.11.zip
You can just write a small wrapper for megarc that emails you if there 
is a problem with the array.
Regards,
Mike
