Dell PowerStore Configuring Volumes

Add new volumes to a volume group

1. Under Storage, select Volume Groups.
2. Click the check box next to the volume group to which you want to add volumes.
3. Select More Actions > Add New Volumes.
   NOTE:You can also open the Create Volumes for Volume Group slide-out panel using the Members tab of the volume group.
4. Enter the volume information in the Create Volumes for Volume Group slide-out panel:
   • Name (or Prefix): When you create a single volume, this name is the name of the volume. When you create multiple volumes, this name is the base name to which a number is appended.
   • Quantity: You can add up to 100 volumes that have the same properties. The system appends the volume name with a number when creating multiple volumes.
   • Size: The size is the quantity of storage that is subscribed for the volume. After you create the volume, you can increase its size but not decrease it. PowerStore supports the creation of thin volumes up to 256 TB in size.
   • Volume Protection Policy (optional): Select a protection policy that contains snapshot and replication rules applicable for the volume. You can add a protection policy after creating the volume.
     NOTE:You cannot assign a protection policy to a volume if it is added to a volume group with an assigned policy. You can assign a policy to a volume group with no assigned policy. In that case, the new volume will not be protected at the volume group level.
   • QoS Policy: Select a QoS policy to set maximum limits on IOPS or bandwidth, or both, on the volume.
   • Volume Performance Policy: Limit I/O throughput and bandwidth to provide more predictable performance. You can select or create a Performance Policy consistent with the I/O priority (High, Medium, or Low).
   • Available Hosts/ Host Groups (optional): Select the hosts/host groups that can access the volume. When you connect the volume to a host/host group, you can specify a Logical Unit Number. If a Logical Unit Number is not specified, the system assigns one by default. You can add the host/host group after creating the volume.

   NOTE:When you add volumes to a volume group or change the size of the volume group during an asynchronous replication session, the changes do not immediately appear on the destination. You can either perform a manual synchronization or wait until the synchronization occurs based on the RPO.
