Determining Individual File Settings for Cached Quick I/O Using
qioadmin
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
Example
To display the current cache advisory setting for the file cust.dbf in the /db01 file system:
$ /opt/VRTS/bin/qioadmin -P cust.dbf /db01
