2. Points of concern
When using the RAID function
■
Make backup copies of important data and programs periodically. In some failures,
■
rebuild of RAID and the data restore from the backup media may become necessary.
To ensure data integrity in time of power failure, it is recommended to use an UPS.
If you require higher availability such as the controller or the data path redundancy,
■
use the dedicated RAID system.
When building or deleting a RAID 1 array
■
The data in the disk is not secured during the build or the deletion of a RAID array.
■
When you newly build a RAID array while the system is running, or delete the built
RAID array once, do not fail to make backup copies of the data. After building a
RAID, you need to install data newly or restore data from the backup media.
The RAID build or the synchronization associated with maintenance takes about an
■
hour for a 146GB HDD.
If there is a system restart during the RAID build or synchronization, the
■
build/synchronization must be started again from the beginning.
When the RAID applied, the volume size is smaller than the size of original disk.
