2.4 Drive Usage Monitoring

The drive usage monitoring function adds up the power-on hours of a drive in this equipment.
If the total power-on hours exceeds the set value, this function notifies in the methods below.
By using this function, you can keep track of the appropriate timing of replacing a drive and
prevent drive failure caused by using the drive for too long.
(1) Hardware status window
(2) Event notification
(3) Popup notification
(4) Remote notification
(5) The hfwDiskStat function in the RAS library
For details about (1) to (4), see "CHAPTER 4 CHECKING THE HARDWARE STATUS".
For details about (5), see "6.1.9 Get function for the drive condition (hfwDiskStat)".
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
• This monitoring function is active while the OS is running, that is, from OS
startup to OS shutdown. When the OS is not running, the amount of the drive
power-on hours is not monitored.
• This function records the serial number (unique ID) of a drive in the equipment
in a drive management information file. If you mount a drive that does not
match the serial number recorded in the drive management information file,
the cumulative power-on hours for the drive is automatically reset.
• This function is not designed to anticipate drive failure, but we recommend
replacing a drive when the power-on hours exceeds the set value from the
viewpoint of preventive maintenance for components with limited life span.
For information about how to replace a drive, refer to "HF-W7500 Model 40
INSTRUCTION MANUAL (manual number WIN-62-0065)".
• 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.
