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
|
Empty | 0 |
Not Empty | 1 |
Corrupt | 2 |
|
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
|
|
The copy's native operational status. Can be either 0("Offline"), 1 ("Online"), |
Sync
|
boolean
|
|
Whether the copy is synced |
Type
|
uint32
|
Sequential | 0 |
Striped | 1 |
Router | 2 |
Image | 3 |
|
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 |
