Class introduction
This class represents an instance of a snapshot virtual disk. There will be one instance of this class for
each snapshot on the system.
Virtual disks can be identified using their keys or by using a globally unique WWN. See the Name
and NameFormat properties.
Indications
• Snapshot creation:
• Filter: "SELECT * FROM CIM_InstCreation WHERE SourceInstance ISA CIM_StorageVirtualDisk"
• Description: VirtualDisks can be created using the CreateVirtualDisk() API or the
HPSVSP_StorageConfigurationService CreateOrModifyElementFromStoragePool() method.
When the system detects a new VirtualDisk, generate a CIM_InstCreation indication.
• Snapshot deletion:
• Filter: "SELECT * FROM CIM_InstDeletion WHERE SourceInstance ISA CIM_StorageVirtualDisk"
• Description: VirtualDisks can be deleted using a proprietary management service or by the
HPSVSP_StorageConfigurationService ReturnToStoragePool method. When a Snapshot is de-
leted, a CIM_InstDeletion indication is generated.
• Snapshot status change:
• Filter: "SELECT * FROM CIM_InstModification WHERE SourceInstance ISA CIM_StorageVirtu-
alDisk AND SourceInstance.OperationalStatus <> PreviousInstance.OperationalStatus"
• Description: When the SnapshotDetails.Status or SnapshotDetails.State changes, a CIM_Inst-
Modification instance is generated by the provider.
• Snapshot health state change:
• Filter: "SELECT * FROM CIM_InstModification WHERE SourceInstance ISA CIM_LogicalDevice
AND SourceInstance.HealthState <> PreviousInstance.HealthState"
• Description: A CIM_InstModification indication is emitted when a Snapshot.HealthState has
changed.
