Key |
CreationClassName
|
string
|
|
CreationClassName indicates the nameof 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_RankExtent'. |
DeviceID
|
string
|
|
An address or other identifying information to uniquely name the LogicalDevice. Is of the form'<StorageSystem.Name>-R<RankID>'. |
SystemCreationClassName
|
string
|
|
The scoping System's CreationClassName. Set to'IBMTSDS_StorageSystem'. |
SystemName
|
string
|
|
The scoping System's Name. |
Read Only |
BlockSize
|
uint64
|
|
Size in bytes of the block which form this Storage Extent. Since the DataType on the Rank is unknown, this is set to 1. |
DataRedundancy
|
uint16
|
|
Number of complete copies of data currently maintained.Value is 1 for RAID5 and 2 for RAID10. |
ElementName
|
string
|
|
A user-friendly name for the object. |
ExtentInterleaveDepth
|
uint64
|
|
Number of StorageExtents to stripe as a collective set. In SCC, this value is defined as the number of stripes to count before continuing to map into the next contiguous set of Extents, beyond the current stripe. |

ExtentStripeLength
|
uint64
|
|
Number of contiguous underlying StorageExtents counted before looping back to the first underlying StorageExtent of the current stripe. It is the number of StorageExtents forming the user data stripe. |

Health state. |
IsBasedOnUnderlyingRedundancy
|
boolean
|
|
True indicates that the underlying StorageExtent(s) participate in a StorageRedundancyGroup. |
IsConcatenated
|
boolean
|
|
True indicates that the data is concatenated across the various StorageExtents in the Group. |
NoSinglePointOfFailure
|
boolean
|
|
Indicates whether or notthere exists no single point of failure. This is true, since DS requires the Array to be RAID5 or RAID10. |
NumberOfBlocks
|
uint64
|
|
|
NumOfDataDisks
|
uint16
|
|
Number of data disks used in this Rank/Disk Group (as opposed to parity and spares) |

PackageRedundancy
|
uint16
|
|
How many physical packages can currently fail without data loss. Value is 1 for both RAID5 and RAID10, 2 for RAID6. |
Primordial
|
boolean
|
|
By definition, Primordial is false. The DiskDriveExtents are considered to be the Primordial extents. |
