Automatic Rebuilding Function

The server supports the disk array automatic rebuilding function for data recovery.

Note: The automatic rebuilding function supports a disk array configuration of RAID levels, RAID1 or RAID5.

Rebuilding is to regenerate all data from a failed disk to a replacement disk. A rebuild is necessary after a failed disk drive is replaced with a new one.

In disk array configuration RAID levels, RAID1 or RAID5 the failed disk does not affect the operation. However, if another disk error occurs before automatic rebuilding, the data may be destroyed. To prevent such an accident, it will rebuild after the failed disk has been replaced.

In a conventional server, the user must select and execute automatic rebuilding using various utilities. The server executes rebuilding automatically. Since the server also supports hot-swapping function, the failed disk can be replaced while the power is on.

Observe the following when using an automatic rebuilding function.

!Do not turn the power off. If power is turned off, automatic rebuilding will not start.

!Use an interval of 60 seconds or more between mounting and dismounting the hard disk drive.

!If a hard disk is being rebuilt, do not replace the hard disk.

Expand Capacity Function

Disk pack capacity can be expanded by adding a disk drive while the system is running. This function is only supported if the server is in the disk array configuration mode.

This function does not utilize operations such as data backup, pack reconfiguration, initialization, restoring the data.

If a hard disk is added under the operation of the Global Array Manager, perform the following.

!After the hard disk is installed, wait for about 60 seconds and click the Scan Device key. Clicking the Scan Device key after the execution of the expand array operation, will display the added disk correctly.
