9-10 Upgrading Your Server
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 RAID10 disk array configuration.
NOTE:
Onboard RAID controller (HostRAID) supports RAID levels
RAID0 and RAID1.
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.)
