Fault Management
Fault Management features combine innovative hardware and software
technology to prevent the loss of critical data and minimize unplanned
downtime.
When a fault occurs, the workstation displays a Local Alert message containing
a description of the fault and any recommended actions. You can then view
current system health by using Compaq Diagnostics for Windows NT. If the
workstation is connected to a network managed by Compaq Insight Manager or
other Simple Network Management Protocol (SNMP)-based management
products (for example, HP OpenView or IBM Tivoli TME10 NetView), the
workstation also sends a fault notice to the network management application.
SMART III Hard Drive Fault Prediction
SMART III is an extension of SMART II capability. A SMART III hard drive
is able not only to monitor and report on its own health, but to fix problems
before they become failures that result in data losses. The SMART III drive
periodically executes read scans of the entire disk. These read scans take place
during periods of inactivity. During the scan, the disk drive will determine the
“health” of each data sector and move data from questionable areas of the disk
to known good areas of the disk. To determine the “health” of the data during
the scan, the drive uses sophisticated methods of Cyclic Redundancy Codes
(CRC) and Error Checking and Correcting (ECC) codes to flag potentially bad
areas of the disk. With today’s multi-gigabyte hard drives, there are areas of the
disk that are not read or written by applications for long periods of time. The
SMART III technology will patrol the entire disk so that when unused or
infrequently used parts of the disk are called upon, the data will be available.
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
workstation detects an abnormal number of transmission errors, the screen
displays a Local Alert message with recommended actions. If the workstation is
on a network, an alert is also sent over the network to the system administrator.
