5. Log in to the Web Management Interface and select Storage-Shelves. The status of the failed disk
should now be OK. The RAID will rebuild automatically but can take up to 5 hours. The RAID
State field on the Storage-RAID tab displays the Percentage Complete.

After replacing the failed disk

When you replace a disk, the RAID initialization process starts. The D2D is fully functional during this
time, however may have reduced performance until the process completes and initialization progress
is 100%.

Email alerts and Log

If you have configured recipients for email alerts on the Web Management Interface, they will be
notified that physical disk(s) added, RAID is being rebuilt and when the rebuild has completed.
The Log also contains an entry when the RAID rebuild completes.

If several disks fail

NOTE:
If the System State shows that RAID has failed catastrophically and no RAID devices are available,
the HP Smart Array RAID controller has failed and needs replacing. See the relevant "HP D2D Backup
System Maintenance and Service Guide" for more information.
