As i said, early storcli versions work fine. Also, MegaCLI has worked just 
fine, as well. but i haven't updated since 8.07.10, so maybe they did the same 
disablement on SubVendorID to later version (but LSI/Avago stopped updating 
MegaCLI a while back in favor of storcli)

Change to storcli made sometime between 1.03.11 and 1.04.07.

finds my PERC in 1.03.11

 Storage Command Line Tool  Ver 1.03.11 Jan 30, 2013

Controller Count = 1

doesn't in 1.04.07

Example of much older MegaCLI using a relatively recent PERC H730 Mini :

If you can't get your head around 'storcli/perccli' syntax or have existing 
scripts that parse MegaCLI (so much fun), realize it has the entire MegaCLI 
parser secretly hidden inside ;)

megacli/storcli won't work, use perccli instead

Alternating green/amber is a predictive failure.

FWIW, sometimes the MegaRAID kernel drivers get wonked (esp when something is 
quite screwed up on the RAID itself), requiring a reboot for megacli to work, 
if you haven't done that.

There was also a split a few years back in LSI/Avago/Broadcom/whatever land 
where 'storcli' and 'perccli' split functionality depending upon whether it was 
a pure LSI device or Dell/other sub-brand.  ('storcli' used to work for Dell 
controllers but then LSI/Ava... switched it to (i presume) look at the PCI 
SubVendor ID and will report "No Controller" if it was a Dell model.

I continue to use MegaCli64-8.07.10  for all my PERC controllers and haven't 
had an issue with anything even current. (It Works For Me)
