Quick I/O is included in the VxFS package shipped with Veritas Storage Foundation for DB2. By default, Quick I/O is enabled when you mount a VxFS file system.
If Quick I/O is not available in the kernel, or the Veritas Storage Foundation for DB2 license is not installed, a file system mounts without Quick I/O by default, the Quick I/O file name is treated as a regular file, and no error message is displayed. If, however, you specify the -o qio option, the mount command prints the following error message and terminates without mounting the file system.
VxFDD: You don't have a license to run this program
vxfs mount: Quick I/O not available

You can use the qiomkfile command to preallocate space for database files and make them accessible to the Quick I/O interface.
See Creating database containers as Quick I/O files using qiomkfile.
You can use the setext command to preallocate space for database files and create the Quick I/O files.
