Run the qio_convertdbfiles command (with no options specified) to rename the file
filename to .filename and creates a symbolic link to .filename with the Quick I/O
extension. By default, the symbolic link uses a relative path name.
The qio_convertdbfiles script exits and prints an error message if any of the database
files are not on a VxFS file system. If this happens, you must remove any non-VxFS files from
the mkqio.dat file before running the qio_convertdbfiles command again.
3. Start up the database.
You can now access these database files using the Quick I/O interface.
▼ To undo the previous run of qio_convertdbfiles and change Quick I/O files back to regular
VxFS files
1. If the database is running, shut it down
2. Run the following command from the writable directory where the mkqio.dat list resides:
$ cd /extract_directory
$ /opt/VRTSdbed/bin/qio_convertdbfiles -u
The list of Quick I/O files in the mkqio.dat file is displayed. For example:
.file1::cdev:vxfs: --> file1
.file2::cdev:vxfs: --> file2
.file3::cdev:vxfs: --> file3
.file4::cdev:vxfs: --> file4
.file5::cdev:vxfs: --> file5
The qio_convertdbfiles command with the undo option (-u) specified renames the
files from .filename to filename and undoes the symbolic link to .filename that was
created along with the Quick I/O files.
