Converting From HFS to VxFS With Quick I/O
If you are currently using HFS file systems, you can use the following procedure to upgrade each
file system used by the database to a VxFS file system with Quick I/O.
▼ To convert an HFS file system to VxFS with Quick I/O
1. Shut down the database.
2. Create a backup of the HFS file system.
3. Unmount the HFS file system.
4. Remove the entry for the HFS file system from the /etc/fstab file.
5. Create a VxFS file system of the same size as the original HFS file system, using the mount
point where the HFS file system was originally mounted. Use the procedure described in
“Creating a VxFS File System” on page 67 to create a VxFS file system.
6. Preallocate Quick I/O files using qiomkfile. Use the procedure described in “Creating
Database Files as Quick I/O Files Using qiomkfile” on page 88.
7. Restore the backup created in step 2 to the Quick I/O files in the new VxFS file system.
8. Restart the database.
