do the following:
1. Make at least one VMS backup of the disk.
2. Use the Set Volume command:
$ SET VOLUME /STRUCTURE_LEVEL=5 < device-name >
Example:
$ SET VOLUME/STRUCTURE_LEVEL=5 $2$DKC100:
Formatting a New Disk
If you plan to use a new (empty) disk, then use the Initialize command to format the
new disk to ODS-5 format, as follows:
$ INITIALIZE/STRUCTURE=5 < device-name >: < volume-label >

INITIALIZE/STRUCTURE=5 $2$DKC100: TESTVOL
Oracle9i Release 2 New Directory Structure
Beginning with this release, the directory structure of Oracle9i for HP OpenVMS
closely resembles that of Oracle9i on UNIX systems. Database Administrators will
more quickly become familiar with Oracle9i as the platform by being able to make
file locations more consistent and predictable.
