Running a consistency check

This topic provides instructions on how to run a consistency check for virtual drives using the LSI Software
RAID Configuration Utility program.

The consistency check operation verifies that all stripes on a virtual drive with a redundant RAID level (RAID
1, RAID 5, and RAID 10) are consistent and the date on the virtual drive is correct. 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. It is recommended that you
run a consistency check at least once a month. You must run a consistency check if you suspect that the
virtual drive data might be corrupted. Ensure that you back up the data before running a consistency check
if you suspect that the data might be corrupted.

To run a consistency check using the LSI Software RAID Configuration Utility program, do the following:

1. Start the LSI Software RAID Configuration Utility program. See “Starting the LSI Software RAID

Configuration Utility program” on page 65.

2. On the main interface of the program, select

Check Consistency

and follow the instructions on the

screen.

The consistency check rate is the rate at which consistency check operations are run on a system. The
consistency check rate can be configured between 0 percent and 100 percent. At 0 percent, the consistency
check is done only if the system is not doing anything else. At 100 percent, the consistency check has a
higher priority than any other system activity.

To configure the consistency check rate using the LSI Software RAID Configuration Utility program, do
the following:

Note:

Using a consistency check rate of 0 or 100 percent is not recommended. The default value is 30

percent.

1. Start the LSI Software RAID Configuration Utility program. See “Starting the LSI Software RAID
