Data Integrity

This chapter discusses various firmware mechanisms that help to

secure the integrity of array data.

No system is completely safe from the threat of hardware faults.

For example, although the chance of occurrence is considerably low,

the occurrences of bad blocks on two (RAID 5) or three (RAID 6)

hard drives can fail a whole data set. When properly configured,

the functions below help to minimize the chance of data loss:

1. Event Triggered Operations (refer to Chapter. 9)

2. Failed Drive Detection

3. Scheduled Maintenance

4. Regenerate Logical Drive Parity

5. Rebuild Priority

6. Verification on Writes

NOTE:

Some of the configuration options may not be available to all sub-

revisions of firmware.

NOTE:

All figures in this chapter are showing examples using the management

hyper terminal screen.
