Configuring Disk Group Compatibility Attributes

Specify a Disk Compatibility value for the disk group to enable your system to use the latest Oracle ASM features.

Note:

You cannot reverse the setting of a disk group compatibility value.

  • ASM Compatibility

    Specify the value that is the minimum software version required for an Oracle ASM instance to mount this disk group.

  • Database Compatibility

    Specify a value that must be less than or equal to the Oracle ASM compatibility. This is the minimum software version that is required for a database instance to use the files in the disk group. If the database compatibility value that you use is greater than the Oracle ASM compatibility, then Oracle Enterprise Manager displays an error.

    Note:

    You cannot modify the database compatibility for an Oracle ASM cluster that is in a rolling migration state.

  • ASM Volume

    Specify a value that is 11.2 or greater to use the Oracle ASM Dynamic Volume Manager (Oracle ADVM) functionality. The ASM compatibility of the disk group must be set to 11.2 or greater to enable Oracle ADVM. Also, the Oracle ADVM volume drivers must be loaded in the supported environment.
