GetSupportedGroupFeatures method of the CIM_ReplicationServiceCapabilities class

This method, for a given ReplicationType, returns the supported group features.

Syntax

uint32 GetSupportedGroupFeatures(
  [in]  uint16 ReplicationType,
  [out] uint16 GroupFeatures[]
);

Parameters

ReplicationType [in]

A value representing the ReplicationType.

GroupFeatures [out]

An array of Supported Features.

One-to-many replication: One source element and multiple targets elements in a group.

Many-to-many: One or more elements in the source group and one or more elements in the target group.

Consistency enabled for all groups: All groups are considered consistent by default.

Empty replication groups allowed: A replication group can have zero elements.

Source group must have more than one element: A group with only one element is not allowed.

Composite Groups: Elements of a group may be from different arrays.

Multi-hop group replication: A group that is the target of a copy operation can be the source of another copy operation at the same time.

Multi-hop elements must have same SyncType: The SyncType of each hop must be the same as previous hop, e.g., mirror, snapshot, clone.

Group can only have one single relationship active: Only one StorageSynchronized association within a group can be active at a given time.

Source element can be removed from group: A source element can be removed even when the group is associated with another replication group.

Target element can be removed from group: A target element can be removed even when the group is associated with another replication group.

Group can be temporary: Group can have a persistence of false, which means the group -- not its elements, may be deleted if it no longer participates in a replication operation.

Group is nameable: In creating a group, it is possible to name the group.

Supports target element count: It is possible to supply one source element and request more than one target element copies.

Synchronized clone target detaches automatically: The clone target group detaches automatically when the target group becomes synchronized; otherwise, the client needs to explicitly request a detach operation.

Reverse Roles operation requires Read Only source: The Reverse Roles operation requires the source element to be in the Read Only mode.

Reverse Roles operation requires resync: For the copy operation to continue, resync of source and target elements is required.

Restore operation requires fracture: The copy operation has completed; however, the synchronization relationship must be fractured.

Resync operation requires activate: For the copy operation to continue, the synchronization relationship must be activated.

Copy operation requires offline source: Instrumentation requires the source element to be offline (not-ready) to ensure data does not change before starting the copy operation.
