Fault Management Features

The array controller and the network operating system support several fault
management and data reliability features that minimize the impact of hard drive
defects on the system.
•
Auto Reliability Monitoring (ARM) is a background process that scans hard
drives for bad sectors in fault-tolerant logical drives. ARM also verifies the
consistency of parity data in logical drives that are using RAID 5. This process
assures that you can recover all data successfully if a drive failure occurs in the
future. ARM operates only when you select RAID 1 or RAID 5.
•
Dynamic sector repair by the controller automatically remaps any sectors that
have media faults (detected either during normal operation or by auto reliability
monitoring).
•
Drive parameter tracking monitors more than 15 drive-operational parameters
and functional tests, allowing the array controller to detect drive problems and
predict drive failure before it occurs. This feature makes possible the Pre-Failure
Warranty on HP hard drives.
Parameters that are tracked include:
— Read and write errors
— Spin-up time
— Cable problems
— Functional tests such as track-to-track, one-third stroke, and full-stroke time
•
Drive failure alert features cause an alert message to be displayed on the
system monitor when drive failure occurs. Different server models use different
messages for different situations.
