be congured between 0 percent and 100 percent. At 0 percent, the rebuild is done only if the system is not
doing anything else. At 100 percent, the rebuild has a higher priority than any other system activity.
To congure the rebuild rate using the LSI Software RAID Conguration Utility program, do the following:
Note: Using a rebuild rate of 0 or 100 percent is not recommended. The default value is 30 percent.
1. Start the LSI Software RAID Conguration Utility program. See “Starting the LSI Software RAID
Conguration Utility program” on page 75
.
2. On the main interface of the program, select Objects ➙ Adapter ➙ Rebuild Rate.
Note: Use up and down arrow keys to navigate between items and press Enter to select an option.
3. Set the rebuild rate by typing a desired value from the keyboard directly.
Running a consistency check
This topic provides instructions on how to run a consistency check for virtual drives using the LSI Software
RAID Conguration Utility program.
A consistency check is an operation that veries that all stripes on a virtual drive with a redundant RAID
level are consistent. The consistency check operation veries correctness of the data on virtual drives that
use RAID 1, 5, and 10 (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. 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. Be sure to back up the data before running a consistency check if you
suspect the data might be corrupted.
To run a consistency check using the LSI Software RAID Conguration Utility program, do the following:
1. Start the LSI Software RAID Conguration Utility program. See “Starting the LSI Software RAID
Conguration Utility program” on page 75
.
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 congured 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 congure the consistency check rate using the LSI Software RAID Conguration Utility program, do
the following:

percent.
