Drive Failure Prediction Function (Smart Monitoring) - Hitachi HF-W6500 60 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. If the drive is an SSD, SMART can also
monitor for the status in which the rate of writes to the SSD increases and exceeds a certain
value. 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 details about (1) to (5), see "CHAPTER 4 CHECKING THE HARDWARE STATUS".
For details about (6), see "6.1.8 Get function for the drive condition (hfwDiskStat)".
When failure of a drive is predicted, a drive hardware failure is likely to occur in
the near future. We recommend you to back up the data and replace the drive.
For information about how to replace a drive, refer to "HF-W6500 Model 60
INSTRUCTION MANUAL (manual number WIN-62-0074)".
NOTE
• It is not possible for the Drive Failure Prediction Function to anticipate all
failures. Therefore, a drive may fail before the Drive Failure Prediction
Function anticipates any failures.
• 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.
