MegaRAID SAS Software User Guide Chapter 10: Maintaining and Managing Storage Configurations | Running a Consistency Check
10.1.1 Running a Group Initialization Initialization prepares the storage medium for use. You can run an initialization on
multiple drives at one time. Follow these steps to run a group consistency check.
1. Select Manage>>Initialize.
The Group Initialization dialog appears, as shown in Figure 267 .
Figure 263: Group Initialization Dialog Box
2. Either check the virtual drives on which to run the initialization, 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 9.21,
Monitoring Rebuilds and Other Processes for more information.
10.2 Running a Consistency
Check
You should periodically run a consistency check on fault-tolerant virtual drives (RAID 1,
5, 6, 10, 50, or 60 configurations; RAID 0 does not provide data redundancy). A
consistency check scans the virtual drive to determine whether the data has become
corrupted and needs to be restored.
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 must
run a consistency check if you suspect that the data on the virtual drive might be
corrupted.
