Replacing a device on RAID1 or RAID5 is done by first removing the faulty device and then
adding a new one. The new device's size must be at least the size of the existing one.
To remove a faulty device from RAID1:
1. In the 'RAID Properties' screen, click the faulty device's Delete icon.
2. Click OK.
To add a new device instead of the one removed:
1. In the RAID Device table in the 'Disk Management' screen, click the Edit icon of
the RAID device; the 'RAID Properties' screen appears with a drop-down list allowing
you to choose the new partition to be added.
2. Choose the partition, and then click OK.
After adding a new device, RAID1 starts a recovery process in which the content of the
existing partition is mirrored to the new device. If the addition or recovery fails, the device
status is set to inactive (this status appears in the 'RAID Properties' screen. In such cases,
the device should be removed and another may be added. You can manipulate your disk
partitions. However, it is recommended to configure your disks before setting up RAID.
Once RAID is configured, you will not be able to delete an underlying partition, or create a
new partition on a disk that one of its partitions is underlying RAID, unless you disable or
delete the RAID device. Changing a disk's partition table when its partitions are under
RAID (even if RAID is disabled) may result in the need to reconstruct the RAID.
