50 Maintaining and Managing Storage Configurations
Running a Consistency Check
You should periodically run a consistency check on fault-tolerant virtual disks
that are on Dell PERC 5/i controllers and Dell PERC 6/i controllers. It is
especially important to do this if you suspect that the virtual disk consistency
data might be corrupted. Be sure to back up the data before running a
consistency check if you think the consistency data might be corrupted.
You can use the Check Consistency stop on error option to select whether
Check Consistency stops when an inconsistency is detected or whether it
fixes the inconsistency, logs the event, and continues.
To run a consistency check, follow these steps:
1
Select Group Operations-> Check Consistency .
The Group Consistency Check window appears.
2 Select the virtual disks that you want to check, or click Select All to select
all of the virtual disks.
3 Click Start to begin the operation.
You can monitor the progress of the consistency check. See Monitoring
Rebuilds and Other Processes
for more information.
NOTE: You can also run a consistency check by selecting the virtual disk icon in
the left panel of the Dell SAS RAID Storage Manager window and selecting the
option on the Operation tab in the right panel. If you select the Automatically fix
errors check box, Dell SAS RAID Storage Manager automatically fixes any
consistency data errors that it finds.
NOTE: Running consistency check impacts the system performance. Make sure to
perform this maintenance task during periods of lower usage.
Scheduling a Consistency Check
You can schedule a consistency check to run at a specified time on fault-
tolerant virtual disks that are on Dell PERC 5/i controllers and Dell PERC 6/i
controllers. This feature makes it easier to run consistency checks on the
virtual disks on a regular basis.
To run a consistency check, follow these steps:
1
Select the Physical View tab in the left panel of the Dell SAS RAID
Storage Manager window and select a controller icon.
