D-20 Understanding Drive Arrays Disk Drive Upgrades Additional storage space may be obtained with the same number of physical drives in a fault-tolerant configuration by replacing these drives with others of higher capacity. By replacing the drives one at a time, the data on the new drive is recreated from redundant information on the remaining drives. After each new drive has been rebuilt, the next can be replaced. After all drives have been replaced and rebuilt, the additional capacity on each drive can be utilized by adding a new logical drive. Array Configuration Utility will automatically recognize the unused space and guide you through the procedures to make use of it.
