Online Capacity Expansion or Extension
In certain cases, the Smart Array 3200 Controller and the Array Configuration
Utility also facilitate storage capacity changes online, without downing the
server or storage system. These cases are:
■ Windows NT 1 or NetWare operating system (NetWare 3.11 not supported)
and
■ Hot-plug drives
Because the Array Configuration Utility reconfigures the Smart Array 3200
Controller, online reconfiguration can only take place if the Array Configuration
Utility is running in the same environment as the normal server applications.
Hot-plug drives are required for online storage changes because non-hot-plug
drives require that the server be powered-down to add or remove the drive. All
ProLiant servers and storage systems support hot-plug drives.
Disk Drive Upgrades
Additional storage space can be gained with the same number of physical drives
in a fault-tolerant configuration by replacing these drives with higher-capacity
drives. By replacing the drives one at a time, the data on the new drive is
recreated from redundant information on the remaining drives. After one new
drive has been rebuilt, the next drive can be replaced. After all drives have been
replaced and rebuilt, the additional capacity on each drive can be used by
increasing an existing logical drive or adding a new logical drive. The Array
Configuration Utility automatically recognizes the unused space and guides you
through the procedures to use it.
1 Online capacity extension under Windows NT requires version 5.0 or later.
