Key |
CreationClassName
|
string
|
|
CreationClassName indicates the name of the class or the subclass used in the creation of an instance. When used with the other key properties of this class, this property allows all instances of this class and its subclasses to be uniquely identified. This value is set to'IBMTSDS_SEVolume'. |
DeviceID
|
string
|
|
An address or other identifying information to uniquely name the LogicalDevice. Is of the form'<StorageSystem.Name>-<DeviceID>'. |
SystemCreationClassName
|
string
|
|
The scoping System's CreationClassName. |
SystemName
|
string
|
|
The scoping System's Name. |

BlockSize
|
uint64
|
|
For Fixed Block volumes, BlockSize is 512. Even if the format is Block520, the actual data is stored in blocks of 512 bytes. For CKD volumes, BlockSize is bytes/cylinder, which is 712140 for 3380 volumes and 849960 for 3390 volumes. |
ConsumableBlocks
|
uint64
|
|
The maximum number of blocks, of size BlockSize, which are available for consumption when layering StorageExtents using the BasedOn association. All blocks on a Volume are usable, so this is set to NumberOfBlocks. |

Type of data organization used. The valid values are Fixed Block and Count Key Data. |
DataRedundancy
|
uint16
|
|
Number of complete copies of data currently maintained. Since the allocation of a Volume on each Rank is not exposed, the DataRedundancy will be set to 1 |
DeltaReservation
|
uint8
|
|
Current value for Delta reservation. This is a percentage that specifies the amount of space that should be reserved in a replica for caching changes. Set to 100. |
ElementName
|
string
|
|
A user-friendly name for the object.For DS, machines the Nickname in the Storage Manager. The maximum length is 16 characters. |

ExtentStatus is'Data Lost'when the StorageVolume has had an indeterminate data loss. ExtentStatus is Broken when the Volume is not online and fully accessible. ExtentStatus is'In-Band Access Granted'when a FULL path to a host is defined (i.e. the volume has an association to a ProtocolController which has an association to an AuthorizedPriviledge which has an association to StorageHardwareID). Otherwise the ExtentStatus is'None/Not Applicable'. It is possible for a volume to be'Broken'and'In-Band Access Granted'simultaneously. |

IsBasedOnUnderlyingRedundancy
|
boolean
|
|
True indicates that the underlying StorageExtent(s) participate in a StorageRedundancyGroup. This is false because the Extent Composition Subprofile is not supported. |
LSS
|
string
|
|
A two-digit hex string representing the LSS of the volume. |
Name
|
string
|
|
A unique identifier for the Volume. Same as DeviceID. |

NoSinglePointOfFailure
|
boolean
|
|
Indicates whether or not there exists no single point of failure. This is true because RAID0 is not supported, and there must be two StorageProcessorSystem's in each DS storage device. |
NumberOfBlocks
|
uint64
|
|
Total number of logically contiguousblocks, of size Block Size, which form this Volume. The total size of the Volume can be calculated by multiplying BlockSize by NumberOfBlocks. For CKD volumes, this is the number of cylinders. |

OtherIdentifyingInfo
|
string
|
|
OtherIdentifyingInfo captures data, in addition to DeviceID information, that could be used to identify a LogicalDevice. For example, you could use this property to hold the operating system's user-friendly name for the Device. |
PackageRedundancy

Number of complete copies of data currently maintained. Since the allocation of a Volume on each Rank is not exposed, the PackageRedundancy will be set to 1 |
