Drive Carrier Indicators
Each drive carrier has two LED indicators: an activity indicator and a status indicator. For RAID
configurations using a controller, the meaning of the status indicator is described in the table
below. For OS RAID or non-RAID configurations, some LED indications are not supported,
such as hot spare. For VROC configurations, refer to the VROC appendix in this manual.
