Drive Failure Prediction Function (Smart Monitoring) - Hitachi HF-W6500 45/40 Feature Manual

2.3 Drive Failure Prediction Function (SMART Monitoring)

The hard drives in this equipment have the Self-Monitoring, Analysis and Reporting
Technology (SMART) function, which constantly monitors the condition of the drives and
anticipates a failure before the failure manifests itself. The drive failure prediction function
notifies in the following methods when there is a possibility that failure may occur in a drive
in near future.
(1) Hardware status window
(2) Event notification
(3) Popup notification
(4) Outputs on the status display digital LEDs
(5) Remote notification
(6) The hfwDiskStat and GetHddPredict functions in the RAS library
For information about items (1) through (6), see "CHAPTER 4 CHECKING THE
HARDWARE STATUS".
This function can be enabled or disabled in the RAS Setup window. If this function is
disabled, notification using the methods above is disabled. For details, see "3.1.3 Using the
RAS Setup window".
NOTE
• It is not possible for the SMART to anticipate all failures. Therefore, a drive
may fail before the SMART anticipates any failures.
• When a failure of a drive is anticipated, back up the data immediately and
replace the drive. For information about how to replace a drive, see "HF-
W6500 Model 45/40 INSTRUCTION MANUAL (manual number WIN-62-
0064)".
• This function only monitors the internal drives that are recognized during OS
startup. If you connect a new drive or replace a drive with a new drive, for
example, for maintenance, it may take a long time to recognize the new drive
at the first startup after the new drive is connected, and the drive may not be
recognized as a drive to be monitored. If this situation happens, restart this
equipment.
• For D Model, the drive failure prediction function is always enabled. You
cannot disable this function.
