this tool help to unify different disk controller output to storcli like format, which is json.
this tool include three basic scripts: sas.py, megacli.py, storcli.py,
which turn disk controller tool(sas3ircu, MegaCli64, storcli64) output into storecli output like format.
disk_utility.py is an example tells you how to use the 3 basic scripts.
by running python disk_utility.py -c you will get this if there's no error:
{
"PD Errors": {},
"PD Not ok": [],
"VD Not ok": []
}
if there's error output will like this (megacli).
