You can give each volume a name. Assign names that indicate how the volumes are to be used. For example, if the first volume will be used to store your customer database, give it a name such as: cust_database. When you create a virtual disk, you can specify the number of volumes you want and their sizes. If the total size of the volume or volumes equals the size of the virtual disk, you will not have any free space, as shown in Figure 3-1. In this example, the volumes in VirtualDisk-1 are equal in size and use all of the virtual disk's space. Without free space, additional volumes cannot be created. You can also create fewer volumes that do not equal the virtual disk's size. This leaves free space in which you can add or expand volumes later as shown by VirtualDisk-2 in the following figure. VirtualDisk-1 VirtualDisk-2 Volume-1 Volume-1 Volume-2 Free space Volume-3 Figure 3-1 A Virtual Disk With Multiple Volumes and a Virtual Disk With One Volume and Free Space After expanding a virtual disk, you can either add a volume or expand a volume to use the new free space. You can also delete one or more volumes and expand a volume into the space. For information about mapping and masking volumes, see "Managing Host Access to Volumes" on page 94.
