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 Configuration Utility program" on page 65. 2. On the main interface of the program, select Objects ➙ Adapter ➙ Chk Const Rate. 3. Set the consistency check rate by typing a desired value from the keyboard directly.
