Hard Drive Installation and Replacement You can now check the new drive configuration by running ORCA or the Array Configuration Utility (see Chapter 7 for details). Upgrading Disk Drive Capacity You can increase the storage capacity on a system even if there are no available drive bays, as long as a fault-tolerance method is running. CAUTION: Since a data rebuild takes about 15 minutes per gigabyte, your system is unprotected against drive failure for many hours, or even days, while the rebuild is in progress. To upgrade disk drive capacity: 1. Back up all data. 2. Replace any drive. The data on the new drive is re-created from redundant information on the remaining drives. CAUTION: Do not replace any other drive until data rebuild on this drive is complete. 3. When data on the new drive has been rebuilt (the Activity LED is no longer illuminated), repeat the previous step for the other drives in the array, one at a time. 4. When all drives have been replaced, you can use the extra capacity to create new logical drives or extend existing logical drives. Expanding and Extending Capacity Array capacity expansion is the addition of physical drives to an array and the redistribution of the pre-existing logical drives over the enlarged array.
