Creating disk groups

Last published : Jul 06, 2026
The Management Server console lets you create a disk group using one or more disks that are available on the hosts in your data center. These disk groups can be used to create volumes.
While creating a disk group, you also have the option of enabling encryption for the disk group.
You cannot create a disk group if there are no free disks available on the host.
This operation can be launched from the contexts of hosts and disks.
To perform this task, your user group must be assigned the Admin role on the host or the Server perspective. The permission on the host may be explicitly assigned or inherited from a parent Organization.
You can also create a shared disk group for a CVM cluster from the Storage Clusters node. More information is available on permissions required for performing operations from the cluster view.
See Permissions required for views and operations on CVM cluster objects.
