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.
Largest Free
Chunk
The total number of bytes in the largest range of blocks available for use on the storage volume.
Health The overall health of the storage volume. See Health states.
Health
Indications
The overall health of the storage volume. See Health states.
I/O Status The status of I/O to the storage volume. See I/O states.
Operational
Status
Indicates how the storage volume is functioning in the cluster. See Operational states.
Create Virtual Volumes dialog box
Use this dialog box to create a virtual volume from an existing device. The Available Devices list shows all available top-level
devices. Select a device from the list and then click Add to add the device to the Selected Devices list.
To create thin virtual volumes, select the Create thin virtual volumes checkbox and make sure that all selected devices are
thin-capable.
NOTE:
Selecting a mix of devices (thin capable and not thin capable) will result in creating thin virtual volumes on thin
devices and thick virtual volumes on thick devices.
Consistency group
About consistency groups
Consistency groups allow a set of volumes to be grouped and have the same set of properties. Grouping volumes ensures
consistency of application data spanning multiple volumes, and provides an application consistent copy of the data that can be
used to restart the application at any metro node cluster in the event of a cluster failure or inter-cluster link failure.
See the Administration Guide for metro node for a detailed description.
Types of consistency groups
Consistency groups can consist of local, global, or distributed volumes. The following table describes the attributes that define
each type of consistency group.
Consistency Group Type
Storage at Clusters Visibility
Local (Local volumes only) cluster-1 or cluster-2 cluster-1 or cluster-2
Global (Local volumes that are visible at
both clusters)
cluster-1 or cluster-2 cluster-1 and cluster-2
Distributed (Distributed volumes only) cluster-1 and cluster-2 cluster-1 and cluster-2
