I could be wrong (as I don't work a lot with RAID) but I believe the status may refer to the status in the RAID array. I'm not sure if that's a standard in the industry or varies by RAID controller. Performing some research resulted in the following RAID statuses:
Normal, Abnormal, Degraded, Crashed, Crashed--Read-Only Mode
If I assign numbers to this and it starts with 0 it would indicate that the status of this drive in the RAID array is Normal. I hope this helps.
