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 hfbDiskStat function in the RAS library
For details, 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
• 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, see "HF-BT1000 INSTRUCTION
MANUAL (manual number BT-62-0002)".
• This function can monitor only the drives on the drive bay1 and 2 recognized
at the 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.
