Q.
Why do the drive activity lights light up on some drives when my system is
idle?
A.
The Smart Array 5i Plus Controller and Battery Backed Write Cache Enabler
performs several different background activities on the drives when the controller
is otherwise idle. For example, the Auto Reliability Monitoring task scans
fault-tolerant volumes for defects and verifies the consistency of parity data. The
Drive Parameter Tracking task periodically checks the performance of all drives
on the controller, normally on an hourly basis.
