[CentOS] LSI MegaRAID system status -- SOLVED

[Raymond Lillard]

Thanks to both of you who replied.

Mr. Vilensky's approach seemed easiest and his google powers
exceed mine.

The link he provided was the key.

The only issue for me was that the megarc URL has been
changed.  I found the package at:
http://www.lsi.com/DistributionSystem/AssetDocument/files/support/rsa/utilities/megaconf/ut_linux_megarc_1.11.zip

Problem solved.

Best to all,
Ray
