Properties

IdTypeRangeDescription
Key
ClusterID string
Cluster ID
CopyID uint32
Copy ID of the mirror copy
StorageVolumeID uint64
Name of Storage volume of the mirror extent
Read Only
Autoexpand boolean
Space-Efficient property. Autoexpand attempts to maintain a fixed amount of unused real capacity on the VDisk. This amount is known as the contingency capacity. The capacity is initially set to the real capacity assigned when the VDisk is created. If the user modifies the real capacity then the contingency capacity is reset to be the difference between the used capacity and real capacity.
BackendVolumeID string
Backend Volume ID is only valid if IBMTSSVC_MirrorExtent.Type==Image or Sequential.Otherwise it will be null.
BackendVolumeName string
Backend Volume Name is only valid if IBMTSSVC_MirrorExtent.Type==Image or Sequential.Otherwise it will be null.
FastWriteState uint32
Empty0
Not Empty1
Corrupt2
Empty: No modified data exists in the cache, this is a normal good state.Not Empty: Some modified data might exist in the cacheCorrupt: Some modified data might have existed in the cache, but any such data has been lost.
FreeCapacity uint64
Space-Efficient property.
Grainsize uint32
Space-Efficient property. Valid options include 32 | 64 | 128 | 256
IsSpaceEfficient boolean
Indicates if this mirror copy is Space-Efficient
Overallocation uint64
Space-Efficient property. Percentage overallocation
PoolID string
The ID of the mdiskgrp on which the copy resides
PoolName string
The name of the mdiskgrp on which the copy resides
Primary boolean
Whether this copy is the primary read copy
RealCapacity uint64
Space-Efficient property. Total real capacity. Allocationson other storage volumes can affect how much space is available toexpand the real capacity.
Status uint16
Offline0
Online1
The copy's native operational status. Can be either 0("Offline"), 1 ("Online"),
Sync boolean
Whether the copy is synced
Type uint32
Sequential0
Striped1
Router2
Image3
The virtualization type of the vdisk copy.
UsedCapacity uint64
Space-Efficient property. Capacity currently allocated in bytes
Warning uint8
Space-Efficient property. Ratio of UsedCapacity vs StorageVolume capacity at which point an indication is triggered
