Operational
Status
Indicates how the device is functioning. See Operational states.
Service Status Indicates whether I/O can proceed on the device. See Service states.
Add capacity to virtual volumes
Use this dialog box to expand a virtual volume using concatenation.
Add Capacity to
Virtual Volume
The selected virtual volume that you want to expand.
Current Capacity The size of the selected virtual volume.
Additional
Capacity Needed
Enter the amount of space to add to this virtual volume. Metro node will look for volumes with at
least that available capacity. To enter the value using a different unit, select the correct unit from the
drop-down list. When you enter the amount of space needed, you can click Show Available to list the
storage volumes with a minimum capacity equal to the additional capacity needed. If you change the
capacity needed, click Show Available again to update Available Storage Volumes list.
Total New
Capacity
The new size of the virtual volume based on the additional capacity needed.
Available storage
volumes
The list of available storage volumes to choose from based on the additional capacity needed. The name
of the storage volume and the largest free chunk available in the storage volume are displayed.
Extent properties
Extent Name
The name of the extent. You can change the name of the extent from this dialog box. By default, extents
are named after the underlying storage volume with the prefix "extent_".
Use Indicates whether the extent is currently in use. Possible values: Claimed or Used.
Used By The name of the device created from the extent.
Storage Volume The name of the underlying storage volume.
Block Count The number of blocks in the underlying extent.
Block Offset The starting block number for the extent. If not specified, extents are created using sequential block
numbers on a storage volume. To specify the starting block number, use the CLI.
Block Size The size of the data blocks used internally when managing I/O. The block size determines the granularity
of disk I/O and the rebuild rate of distributed devices.
Capacity The size of the extent.
Thin Capable Indicates if the underlying storage volume is thinly-provisioned.
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.
● 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 Indicates the overall health of the extent. See Health states.
Health
Indications
Displays the reasons for the extent's unhealthy state.
I/O Status The status of I/O to the underlying storage volume. See I/O states.
