CAUTION:
The default snapshot space allocated by the system is two times the size of source
virtual disk. That is the best value of our suggestion. If user sets snapshot space by
manually and lower than the default value, user should take the risk if the snapshot
space is not enough and the clone job will fail.
Clear Clone
To clear the clone job, please follow the procedures.
1.
Select the source virtual disk, and then click
▼
-> Clear Clone.
2.
Click OK button to clear clone job.
Clone Constraint
While the clone is processing manually, the
increment data of the virtual disk is over the
snapshot space. The clone will complete the
task, but the clone snapshot will fail. At the
next time, when trying to start clone, it will
get a warning message “This is not enough
of snapshot space for the operation”. The
user needs to clean up the snapshot space
in order to operate the clone process. Each
time the clone snapshot failed, it means that
the system loses the reference value of
incremental data. So it will start a full copy
at the next clone process.
When running out of the snapshot space, the
flow diagram of the virtual disk clone
procedure will be like the following.
System Buzzer
The system buzzer features are listed below:
The system buzzer alarms 1 second when system boots up successfully.
The system buzzer alarms continuously when there is error occurred. The alarm will be stopped after
error resolved or be muted.
The alarm will be muted automatically when the error is resolved. E.g., when RAID 5 is degraded and
alarm rings immediately, user changes / adds one physical disk for rebuilding. When the rebuilding is
done, the alarm will be muted automatically.
