Dell EMC PowerEdge RAID Controller S130 User’s Guide

Consistency check (CC) is a background operation that verifies and corrects the mirror or parity data for fault-tolerant physical disks. It is recommended that you periodically run a consistency check on the physical disks.

By default, CC corrects mirror or parity inconsistencies. After the data is corrected, the data on the primary physical disk in a mirror set is assumed to be the correct data and is written to the secondary physical disk mirror set.

The CC operation reports data inconsistencies through an event notification. A CC cannot be user-initiated in the BIOS configuration utility, accessed using Ctrl + R. However, CC can be initiated using OpenManage Server Administrator Storage Management. For more information, see the OMSA user’s guide at www.dell.com/openmanagemanuals.
