To enable or disable individual file settings for Cached Quick I/O automatically

after a reboot or mount

◆

Add cache advisory entries in the /etc/vx/qioadmin file as follows:

device=/dev/vx/dsk/<diskgroup>/<volume>

filename,OFF

filename,ON

For example, to make the Cached Quick I/O settings for individual files in the

/db01 file system persistent, edit the /etc/vx/qioadmin file similar to the

following:

# List of files to cache in /db01 file system

device=/dev/vx/dsk/PRODdg/db01

cust.dbf,OFF

system.dbf,OFF

stk.dbf,ON

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.
