Fault Notification and Recovery
Fault Notification and Recovery features combine innovative hardware and software technology
to prevent the loss of critical data and minimize unplanned downtime.
When a fault occurs, the computer displays a Local Alert message containing a description of the
fault and any recommended actions. You can then view current system health by using the
Compaq Management Agent. If the computer is connected to a network managed by Compaq
Insight Manager LC, Compaq Insight Manager or other management products from Compaq
Management Solutions Partners, the computer also sends a fault notice to the network
management application.
3.3.1
Processor Fault Prediction and Prefailure Warranty
When the processor encounters an excessive number of error checking and correcting (ECC)
cache memory errors, the computer displays a Local Alert Message. This message contains
detailed information about the faulty processor, allowing you to take action before you experience
non-correctable cache memory errors. The Prefailure Warranty allows you to replace these
processors, free of charge, before they actually fail. Processors with ECC cache memory are
available on select Compaq products.
3.3.2
SMART Hard Drive Fault Prediction for IDE Drives
The SMART hard drive monitors hard drive activity to predict failures and, in some cases, fix
faults before failures occur. Fault prediction and failure indication parameters, such as abnormal
variations in spinup and seek times, or non-correctable read and write errors, are tracked to
determine the hard drive condition. Should these errors become significant, the computer displays
a warning message. The warning gives you time to back up the hard drive and replace it prior to
experiencing downtime or loss of data. The Prefailure Warranty for SMART hard drives allows
you to replace these drives, free of charge, before the drives fail.
SMART hard drives are compliant with the Small Form Factor Committee Specification for Self-
Monitoring, Analysis, and Reporting Technology (SMART). SMART is the industry standard
technology, pioneered by Compaq and originally called IntelliSafe, that allows you to prevent
data loss and minimize downtime, in concert with Compaq Management Agents.
3.3.3
Drive Protection System for IDE Drives
The Compaq Drive Protection System (DPS) is a diagnostic tool built into the hard drives
installed in select Compaq products. DPS is designed to help diagnose problems that might result
in unwarranted hard drive replacement. When Compaq products are built, each installed hard
drive is tested using DPS and a permanent record of key information is written onto the drive.
Each time DPS is run, test results are written to the hard drive. You can use this information to
help diagnose conditions that caused you to run the DPS software.
3.3.4
Ultra ATA Integrity Monitoring
Ultra ATA Integrity Monitoring monitors the integrity of data as it is transferred between an Ultra
ATA hard drive and the system’s core logic. If the computer detects an abnormal number of
transmission errors, the computer displays a Local Alert message with recommended actions. An
alert is also sent over the network to the system administrator.
