4. Background Initialize
The Background Initialize is automatically executed when RAID5 virtual disk is created in
the disk group composing of five or more HDDs.
The Background Initialize performs the parity generation processing to the area not
initialized in the background. The processing is equivalent to that of Consistency Check.
However, the Background Initialize is not performed in the following cases.
Full Initialize has already been executed and completed normally before
executing Background Initialize.
(*) Full Initialize is a function to clear the entire area of a virtual disk with "0".
Consistency Check has already been executed and completed normally before
executing Background Initialize.
Rebuild has already been executed and completed normally before executing
Background Initialize.
"Yes" is specified for "Disable BGI" in VD Definition.
The Background Initialize is executed again if any of the following cases occurred in the
virtual disk on which the Background Initialize has completed.
When the virtual disk is degraded or offline, you execute Make Online to HDD
being in offline status, and the virtual disk becomes Optimal state.
When you replace the disk array controller with the maintenance parts and others.
When you execute Reconstruction to existing virtual disk to make RAID5 VD with
five or more HDDs.
Notice
Note the following for Background Initialize:
During Background Initialize, the processing rate is decreased due to
much load.
Background Initialize will resume a few minutes later even if it is
interrupted.
