You can interrogate the config of the card and the raid 10 array using
the megaraid cli package - you need to read the (frankly terrible)
manual to discover which switches to use to determine battery and
cache status etc. If you email me privately I'll get you a link to the
relevant docs!
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
