Creating virtual disks
Before creating a new virtual disk, decide from which storage pools you want to allocate capacity to
the virtual disk. You can allocate all the capacity for the virtual disk for one storage pool, or you can
allocate capacity from a combination of storage pools. To create a virtual disk, you need at least one
storage pool with available free capacity. For information about creating storage pools, see
“Creating storage pools” on page 85.
Aside from the initial allocation of capacity to the virtual disk, the virtual disk creation wizard enables
you to set various other virtual disk attributes. In most cases, these settings are optional and can be
modified later, as described in the following procedure.
To create a virtual disk:
1. In the navigation tree, expand the Entities node.
2. Right-click the Virtual Disk node.
