Chapter 10: Maintaining and Managing Storage Configurations | Running a Consistency Check MegaRAID SAS Software User Guide 10.2 Running a Consistency Check Figure 194: Group Initialization Dialog Box 2. Check the virtual drives to run the initialization on or click Select All to select all of the virtual drives. 3. Click Start. You can monitor the progress of the group initialization. See Section 9.9, Monitoring Rebuilds and Other Processes for more information. The Consistency Check operation verifies correctness of the data in virtual drives that use RAID levels 1, 5, 6, 10, 50, and 60. (RAID 0 does not provide data redundancy). For example, in a system with parity, checking consistency means computing the data on one drive and comparing the results to the contents of the parity drive. You should run a consistency check on fault-tolerant virtual drives periodically. You must run the consistency check if you suspect that the virtual drive data might be corrupted. Be sure to back up the data before running a consistency check if you think the data might be corrupted. To run a consistency check, first set the consistency check properties and then schedule the consistency check. This section explains how to set the properties, schedule the check, and run the consistency check. Page 314
