Enabling DMAPI

Whether or not the file system can be monitored and managed by the GPFS Data Management API (DMAPI) may be specified at file system creation by using the -z option on the mmcrfs command or changed at a later time by using the -z option on the mmchfs command.

The default is not to enable DMAPI for the file system.

For further information about DMAPI for GPFS, see the Programming reference section.
