Auto Reliability Monitoring

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 drives with data guarding or distributed data
guarding. 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 , RAID 4, or RAID 5.

Dynamic Sector Repairing

Using the dynamic sector repairing process, the controller automatically
remaps any sectors with media faults it detects either during normal operation
or during auto reliability monitoring.

Drive Parameter Tracking

Drive parameter tracking monitors more than 15 drive operational parameters
and functional tests. This includes parameters such as read, write, and seek
errors, spin-up time, cable problems, and functional tests such as track-to-
track seek time, one-third stroke, and full stroke seek time. Drive parameter
tracking allows the SMART-2DH Controller to detect drive problems and
predict drive failure before they actually occur. It also makes pre-failure
warranty possible on Compaq disk drives.

Drive Failure Alert Features

Drive failure features produce various drive alerts or error messages
depending on the Compaq server model. Refer to the documentation included
with your server to determine what drive failure features are included on your
server model.
Other Compaq options such as Compaq Insight Manager and Compaq Server
Manager/R provide additional drive failure features. See your Authorized
Compaq Reseller for more information on these products.
