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 ever occurs. 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; functional tests such as track-to-track seek time, one-third stroke, and full stroke seek time. Drive parameter tracking enables the Smart Array 3200 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.
