Rebuild a Logical Drive (RAID set)
If a physical drive in a logical drive fails and a hot spare is not available to
automatically replace it, the logical drive goes into a critical state. In this
state, the logical drive does not protect the data with redundancy. All data
on the logical drive is lost if another drive fails.
Note If you replace a failed drive with a new drive, you must use the same slot
that the failed drive used.
To recover the logical drive from critical state, replace the failed hard
drive with a new one and rebuild the logical drive:
1 Replace the failed drive. (Follow the instructions that come with the
drive.)
2 Using the NetStorage web interface, click the Storage tab, then select
Physical Drives.
3 Verify that the drive is recognized by the system. Click Actions, then
select Refresh to update the table. If the drive is not recognized (as
unassigned), reboot the system.
4 Once the drive is recognized and is in an unassigned state, click
Actions, then select Rebuild Logical Drive.
5 You are prompted to select a logical drive to rebuild. Normally, there is
only one drive to select. Select the desired logical drive to rebuild.
6 Click OK.
The rebuilding process may take one or more hours. To monitor the status
of the drive on the Physical Drives page, click Actions, then select
Refresh to update the table. When the drive is rebuilt, its status changes
from Rebuilding to Online.
