10. SOFTWARE RAID1
10.6.4 Rebuild function of RAID1
If you manually select the direction of rebuild during a rebuild process, make
sure you select the right direction. Otherwise, the data stored in the HDDs may
be lost.
Until rebuild is complete, avoid shutting off the power for the Equipment or
attaching and detaching HDDs. Otherwise, the data may be corrupted or
failure may result.
If read or write error occurred during rebuild, it may take about one minute
after an error message is displayed until next input is allowed.
This function rebuilds RAID1 (copying data from the HDD mounted in the drive bay 1 or 2
to the other HDD). When the rebuild is complete, the status of the software RAID1 is set to
be normal.
This function is used for, for example, recovering from HDD failure during system
operation or fall-back operation due to power failure or reset.
In the case of aforementioned conditions, the direction of rebuild is automatically selected.
Otherwise, a message is displayed to prompt you to select the direction of rebuild. Follow
the message to select the direction and start rebuild.
Be noted that this function uses an HDD in the normal state as the copy source for rebuild.
Make sure that at least one of the mounted HDDs is in the normal state. An HDD is in the
normal state if and only if the status of the HDD is displayed as "ONLINE" on the status
display for RAID1.
The following shows how to use this function.
