Why does nobody bother enabling Degraded Performance Optimization, Inconsistency Repair, ....

Hello,

I have multiple P400/P412/P800 smart array controllers, and I am now in the process re-initializing one of them. So I had a look on configuration options, and came accross 4 parameters which nobody seems to bother to touch:

Degraded Performance Optimization: Disabled
Inconsistency Repair Policy: Disabled
Wait for Cache Room: Disabled
Surface Analysis Inconsistency Notification: Disabled

Probably because they are nowhere really explained? I only found references to those parameters in the Array Configuration Reference Guide. However, no explanation was added.

Can somebody explain why they are never brought up, and what they actually do?

I was specifically looking at scrubbing, described as "Dynamic Sector Repairing continually performs background surface scans on the hard disk drives during inactive periods and automatically remaps bad sectors, ensuring data integrity" in the Quick references.

Do I have e. g. to enable "Inconsistency Repair Policy" or 'Surface Analysis Inconsistency Notification" on my controller to have scrubbing functionality?

kind regards,
