You can determine whether Cached Quick I/O is enabled or disabled for individual files by displaying the file's cache advisory setting using the qioadmin command.

Note:

To verify caching, always check the setting of the flag qio_cache_enable using vxtunefs, along with the individual cache advisories for each file.

To display the current cache advisory settings for a file

Use the qioadmin command with the -P option as follows:
```
    $ /opt/VRTS/bin/qioadmin -P filename /mount_point
```
For example, to display the current cache advisory setting for the file dbfilein the /db01file system:
```
    $ /opt/VRTS/bin/qioadmin -P dbfile /db01
```
```
    dbfile,OFF
```
