Chapter 3 Managing Storage 85
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.
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.
