Chapter 6. Volume configuration 305
In this example, the Create option has been selected (the volume-to-host mapping can be
performed later). At the end of the volume creation, following confirmation window appears as
shown in Figure 6-15.

Success is also indicated by the state of the Basic volume being reported as formatting in the
Volumes pane as shown in Figure 6-16.

Notes:
Fully allocated volumes are automatically formatted through the quick initialization
process after the volume is created. This process makes fully allocated volumes
available for use immediately.
Quick initialization requires a small amount of I/O to complete, and limits the number of
volumes that can be initialized at the same time. Some volume actions, such as moving,
expanding, shrinking, or adding a volume copy, are disabled when the specified volume
is initializing. Those actions are available after the initialization process completes.
The quick initialization process can be disabled in circumstances where it is not
necessary. For example, if the volume is the target of a Copy Services function, the
Copy Services operation formats the volume.The quick initialization process can also
be disabled for performance testing, so that the measurements of the raw system
capabilities can take place without waiting for the process to complete.
