Class CIM_DiskGroup
extends CIM_CollectionOfMSEs

A DiskGroup is a named collection of DiskDrives and the StorageExtent(s) accessed via those Drives. The collection is used to limit the BasedOn relationships of the Extents in the DiskGroup. Extents in the Group can NOT be BasedOn storage accessed from Drives outside of the Group. For example, a SoftwareVolume created 'within the DiskGroup' is restricted to be completely accessed using Drives in the Group. Actions such as 'replicate' or 'migrate' on an Extent must operate within the scope of the Extents present in the DiskGroup.

DescriptionstringThe Description property provides a textual description of the object.None TRANSLATABLE= true
ElementNamestring
DescriptionstringA user-friendly name for the object. This property allows each instance to define a user-friendly name IN ADDITION TO its key properties/identity data, and description information. Note that ManagedSystemElement's Name property is also defined as a user-friendly name. But, it is often subclassed to be a Key. It is not reasonable that the same property can convey both identity and a user friendly name, without inconsistencies. Where Name exists and is not a Key (such as for instances of LogicalDevice), the same information MAY be present in both the Name and ElementName properties.None TRANSLATABLE= true
