Vmctlmc
This option specifies the management class to use when backing up virtual machine control files.
By default, virtual machine control
files are bound to the default management class. The vmmc option
can be used to specify a different management class to which virtual machine data
and virtual machine control
files are bound. The vmctlmc option overrides the
default management class and the vmmc option for
the virtual machine control
files.
Under certain conditions, it might be desirable or necessary to bind the control files to a different management class than the data files.
The vmctlmc option is required if virtual machine data files are backed up to tape. Virtual machine control files must be backed up to a disk-based storage pool that does not migrate to tape. The storage pool can be composed of random access volumes and sequential file volumes; the storage pool can also be a deduplicated pool. Use the vmctlmc option to specify a management class that stores data in such a storage pool.
Restriction: The
management class that is specified by the vmctlmc option
determines only the destination storage pool for virtual machine control
files. Retention of the control files is determined by the vmmc option,
if specified, or by the default management class. The retention for
the virtual machine control
files always matches the retention of the virtual machine data
files.
Options File
Place this option in the client options file dsm.opt.
