Many of our controllers support consistency checks. Patrol reads occur on most of our controllers automatically. Patrol reads check for faulty blocks, and a patrol read uses very little controller resources. A consistency check verifies the data within a block. The process of data verification also verifies if the block is accessible, so a consistency check also performs block checks like a patrol read. The controller will attempt block recovery if it finds any issues.

Most of our controllers require OpenManage Server Administrator or the RACADM toolset to initiate a consistency check.
