Smart Array Controller Technology: Drive Array Expansion and Extension volume extension Volume extension grows the storage space of a logical drive (see figure 3). During this process, an administrator adds new storage space to an existing logical drive on the same array, usually after the array has been expanded. An administrator may have gained this new storage space by either capacity expansion, as previously discussed, or by deleting another logical drive on the same array. figure 3. Volume extension grows the size of a logical drive. Unlike capacity expansion, the OS must be aware of changes to the logical drive size. The following operating systems support online volume extension: • Microsoft Windows 2000, NT 4.0 • Novell NetWare 4.2, 5.x • SCO UnixWare 7.1.x Offline volume extension is possible for some operating systems by backing up data, reconfiguring the array, and restoring the data from backup. Refer to the OS documentation for additional information. 5
