Creating volume groups and assigning source volumes

Create a volume group and add source volumes.

Using the management GUI

To create a volume group, complete these steps:

In the management GUI, select Volumes > Volumes Groups.
Click Create Volume Group.
On the Create Volume Group page, enter the volume group name. If you do not specify a volume group name, the system automatically assigns the name.
To assign volumes, select the following options:
Choose existing volumes
Select this option if you want to add existing volumes to a volume group by completing these steps:
1. Select Choose existing volumes and click Next.
2. From the list, select the volumes that you want to add to the volume group.
3. Click Create Volume Group.

To create and configure a new volume group and assign volumes to that group, complete these steps:

To create the new volume group, enter the following command:
```
mkvolumegroup -name volumegroup_name -external
```
where volumegroup_name specifies a volume group name. The external defines that the policy is scheduled by an external scheduling application. This command creates the volume group and assigns the policy to the volume group.
After creating the volume group, either create new volumes or change existing volumes and assign them to volume group that you created in Step 1.
If you are assigning a new volume to the volume group, enter the following command:
```
mkvolume -pool <pool_name_or_id> -volumegroup <volumegroup_name_or_id> -size <disk_size>
```
where <pool_name_or_id> is the name or identifier of the parent pool that contains the Safeguarded backup location; <volumegroup_name_or_id> is the name or identifier of the volume group; and <disk_size> indicates the capacity that is provisioned for the volume from the parent pool.
If you are assigning existing volumes to the volume group, enter the following command:
```
chvdisk -volumegroup <volumegroup_name_or_id> <name_or_id>
```
where <volumegroup_name_or_id> is the name or identifier of the volume group and <name_or_id> of the volume.
