7-12 Upgrading Your System

When the hard disks are in the disk array configuration, you can restore the state before an error using the auto-rebuild feature that stores the data in the old hard disk into a new one.

The auto-rebuild feature is available for the RAID1, RAID5, or RAID0+1 disk array configuration.

Auto-rebuild is carried out when you hot-swap a failed hard disk with a new one (replace the disk while the server is powered). While auto-rebuild is in progress, the DISK lamp flashes green and amber alternatively to indicate it.

IMPORTANT:

!When auto-rebuild fails, the DISK lamp lights in amber. Remove and install the hard disk again to restart auto-rebuild.

!If the disk array monitoring utility is installed, it may display or act as follows. If the DISK lamp does not light in amber after auto-rebuild, however, auto-rebuild has completed successfully.

Displays "Rebuild was cancelled" on the screen while auto-rebuild is in progress.

Appears to stop and restart auto-rebuild.

Observe the following notes for auto-rebuild.

!Do not power off the server in the period between a hard disk error and completion of auto-rebuild.

!When you removed a hard disk, wait at least 90 seconds before installing the hard disk back again.

!Do not replace another hard disk while rebuilding is in progress. (The DISK lamp flashes in green and amber alternatively while rebuilding the hard disk.)
