HP MR Gen10 Plus User Manual

Consistency checkConsistency check
A consistency check operation verifies the correctness of the data in logical drives that use RAID levels 1, 5, 6, 10, 50, and 60. For
example, in a system with parity, checking consistency means calculating the data on one drive and comparing the results to the
contents of the parity drive.
Periodically run a consistency check on fault-tolerant logical drives. Because RAID 0 does not provide data redundancy, you cannot run
a consistency check on RAID 0 logical drives.
To run a consistency check, you must first set the consistency check properties, and then you can either:
Schedule a consistency check to be run at an interval that you define.
Start the consistency check operation immediately.
The consistency check priority value ranges from 1 to 100.
You can use the following modes for the consistency check:
Concurrent - Run consistency check concurrently on all logical drives.
Sequential - Run consistency check on one logical drive at a time.
Disable - Disables consistency check.
Access the consistency check rate by selecting Set Adjustable Task Rate under the More Actions menu then locating it under the
Priority Percentage column. Enter a number from 1 to 100. The higher the number, the faster the consistency check is performed (and
the system I/O rate might be slower as a result).
