disk_controller

this tool help to unify different disk controller output to storcli like format, which is json.

Usage

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).

{
  "PD Not ok": [

        "DID": "13",
        "Drive Temperature": "53C (127.40 F)",
