Preparing for Online Capacity Expansion under NetWare 4.2 About Capacity Expansion under NetWare 4.2 Normally, to add capacity you must shut down the server to reconfigure and then restore data, or you must add the new storage space as a new volume. The Online Capacity Expansion feature allows you to expand an existing logical drive without shutting down the server. Under NetWare 4.2, use virtual sizing to prepare for online capacity expansion. Virtual sizing is enabled separately on each logical drive. When enabled, the controller presents to the operating system a logical drive of 144 GB, which is the default size. Only a part of the 144 GB logical drive exists as actual physical storage; the remainder is virtual storage. You configure volumes to use only the actual physical space, while the virtual space allows room for online expansion. NOTE The 144 GB default size of the logical drive that the controller initially presents to the operating system is the minimum size. The size can be increased. 80
