Virtual volume properties
Virtual Volume
Name
The name of the virtual volume. You can change the name in this field.
Supporting
Device
The device on which the virtual volume was created.
Consistency
Group
Identifies the metro node consistency group to which this virtual volume belongs.
Locality Designates where the virtual volume is located. Values can be cluster 1, cluster 2 or distributed.
Visibility Indicates where a virtual volume is visible: Global (both clusters) or Local (only at this cluster).
Expansion
Method
The expansion method available for this volume. Possible values:
concatenation — The volume can be expanded using Concatenation or RAID-C expansion.
storage-volume — The volume can be expanded to the Expandable capacity using storage volume
expansion.
not-supported — The volume does not support expansion.
Expandable By The amount of space that is available for volume expansion. A volume that has an Expandable by of 0 can
still be expanded using concatenation. A volume that has an Expandable by of > 0 can be expanded using
storage volume expansion.
Expansion Status The expansion status of the volume. The volume can be:
- (dash) — This volume can be expanded.
failed — The last volume expansion on this volume failed.
unknown — The volume expansion status is unknown.
in-progress — The volume cannot be expanded because it has a volume expansion in progress.
Block Count The number of blocks in the underlying extent.
Block Size The size of a single block, in kilobytes.
Capacity The size of the virtual volume.
Thin Enabled Indicates if the virtual volume is created as a thin volume. Possible values:
● Enabled — The volume was created as a thin volume.
● Disabled — The volume was not created as a thin volume although the underlying storage is
thin-capable.
● Unavailable — The underlying storage in not thin-capable.
You can change this property for XtremIO, VMAX and VNX virtual volumes only in the CLI. Refer to the
CLI Guide for information.
Storage Array
Family
The family of arrays that the supporting array belongs to. Possible values:
● XTREMIO — The array belongs to the XtremIO family of arrays.
● CLARiiON — The array belongs to the VNX or Unity family of arrays.
● SYMMETRIX — The array belongs to the VMAX or Symmetrix family of arrays.
● Mixed — The supporting arrays belong to different array families. For example, you might have a
RAID-1 device with one leg on a VNX array and the other leg on a VMAX array.
● Other — Metro node does not recognize the array or does not support creating thin volumes on the
array.
● - (dash) — The Storage Array Family property is not populated. There may be a connectivity
problem.
Health The overall status of the virtual volume. See Virtual volume states.
Health
Indications
The reasons for the virtual volumes unhealthy state. See Virtual volume status.
Operational
Status
Indicates how the virtual volume is functioning in the cluster. See Virtual volume status.
Service Status Indicates how the virtual volume is functioning in the cluster. See Virtual volume status.
