GetSupportedThinProvisioningFeatures
uint32 ReplicationServiceCapabilities.GetSupportedThinProvisioningFeatures(
[IN] uint16 ReplicationType,
[OUT] uint16 SupportedThinProvisioningFeatures[] );
For a given ReplicationType this method returns the supported features related to thin provisioning.
Possible SupportedThinProvisioningFeatures are:
1. Thin provisioning is not supported: Feature is unavailable.
2. Zeros written in unused allocated blocks of target: In copying thin to full, the unused blocks
of target will be written with zeros.
3. Unused allocated blocks of target are not initialized: In copying thin to full, the unused blocks
of target will remain uninitialized.
For “Synchronous Clone Local”, “Asynchronous Clone Local”, “Synchronous Mirror Remote” and
“Asynchronous Morror Remote” ReplicationTypes, the SupportedThinProvisioningFeatures shall
contain only 2 (if the target volume has a policy of tp_bzero) and 3 (if the target volume has a
policy of no_tp_zero).
For Synchronous Snapshot Local ReplicationType, the SupportedThinProvisioningFeatures shall not
contain anything since the options seem to apply only to physical copy.
GetSupportedMaximum
uint32 ReplicationServiceCapabilities.GetSupportedMaximum(
[IN] uint16 ReplicationType,
[IN] uint16 Component,
[OUT] uint64 MaxValue );
This method accepts a ReplicationType and a component, it then returns a static numeric value
representing the maximum number of the specified component that the service supports. A value
of 0 indicates unlimited components of the given type. In all cases the maximum value is bounded
by the availability of resources on the computer system. If the information is not known, the method
returns 7, which indicates, Information is not available.
If ReplicationType parameter contains an unsupported value, an error of Not Supported (2) shall
be returned.
The following table shows the list of components that can be specified:
