Converting From HFS to VxFS For Oracle Disk Manager
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. You can then use the Oracle Disk Manager
feature.
Caution Do not upgrade your root file system to VxFS.
Prerequisites
◆ Configure Oracle Disk Manager according to “Setting Up VERITAS Extension for Oracle
Disk Manager” on page 130.
▼ To convert an HFS file system to VxFS for Oracle Disk Manager
1. Shut down the database.
2. Create a backup of the HFS file system.
3. Unmount the HFS file system.
4. Remove the HFS entry in 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 ODM files using odmmkfile. Make the files the same size or larger than what
they were on the original HFS file system.
7. Restore the backup created in step 2 to the new VxFS file system.
8. Restart the database.
