while

megasasctl -H ( V0.4.3) reports:
a0 IBM ServeRAID-MR10i SAS/SATA Controller encl:1 ldrv:1 batt:FAULT, unknown charge state

which looks wrong for me.

Same problem here with an IBM x3550 M3 (LSI MegaSAS 9260):

# megasasctl -H
a0 ServeRAID M5014 SAS/SATA Controller encl:1 ldrv:2 batt:FAULT, low voltage

Does anyone have an idea why megasasctl is not reporting correctly the battery status?

Hi,

I'm sorry, but I'm not the author of megactl... I'd suggest you to use megacli instead, or report this bug directly on sourceforge megacli's homepage, but the project looks really dead...

If someone has good low level programming skills, I'd be glad to integrate your patch ;-)
