hi, my name is javagyt,we discussed some problems about raid in github.The reasoning for that is that the iDrac6 initializes before the raid controller does, so that information isn't available to it yet. information for a percentage field called Media_Wearout_Indicator, or other jargons indicators like Longterm Data Endurance - which don't exist - Yes I did check two SSDs, both lack these fields.
For the command line I suggest you install the smartmontools package and play around with smartctl. Specifies the frequency of performing consistency checks. Storcli check disk health In my setup, this will make the activity LED blink really fast.
