That's assuming the MegaCli utility will work against IBM's version of
the card.  They use an LSI chipset for the RAID parts, but I don't know
if the card is so similar that it will talk using that utility or not.

The main useful site here is
http://tools.rapidsoft.de/perc/perc-cheat-sheet.html ; here's how to
dump all the main config info from an LSI card:

MegaCli64 -LDInfo -Lall -aALL

You want to see a line like this:

  Current Cache Policy: WriteBack, ReadAheadNone, Direct, No Write Cache
if Bad BBU

For the arrays.  And then check the battery like this:

MegaCli64 -AdpBbuCmd -aALL
