Megacli does not want to talk to a PERC H200 adapter on one of our systems. This is what happens (all commands run as "root"):
megacli -AdpAllInfo -aAll
Exit Code: 0x00
System description (I did not configure this system):
CentOS release 6.6 (Final)
Rocks release 6.2 (SideWinder)
Relevant (probably) dmesg lines:

All other megacli commands tried return nothing but "Exit Code: 0x00".
Is some other tool needed to talk to an H200?
