Dell PowerStore Configuring Volumes

You can perform the following operations from the Volumes page within the PowerStore Manager:

• Create a volume.
  • Associate a specific application with a volume.
    NOTE:In PowerStore 2.1, this step is required when creating a volume. You can change the category of application and specific application at any time later.
  • Optionally, you can associate the volume with a volume group and with a host or host group.
• Modify volume properties.
• Delete a volume, after unmapping the volume from any hosts; and recover the volume from the recycle bin, if wanted.
• Delete a volume group; and recover the volume group from the recycle bin, if wanted.
• Expand the volume size.
• Modify the performance policy of a volume.
• Assign, unassign, and modify the QoS policy of a volume.
• Migrate a volume to a different appliance.
• Add a volume to or delete a volume from the dashboard watchlist.
• Map or unmap a volume to a host.
• Assign or unassign a protection policy.
• Restore content from a snapshot.
• Gather support materials.
• Create a thin clone of a volume.
• Refresh content from a related volume.
• Enable a Metro configuration for a volume.

To monitor the capacity, performance, alerts, protection status, and host mapping of a volume, click the name of the volume you want to view.

The following list describes some important considerations when creating volumes:

• Your system creates volumes as thin volumes.
• When a volume is created, the Resource Balancer determines on which appliance the volume is provisioned, although you can select the appliance from the drop-down list. If the Resource Balancer is choosing a default appliance, it does not choose a volume has been mapped to a specific host or host group. In such cases, the volume is created only on an appliance that sees this host or host group.
• Volumes can be between 1 MB and 256 TB in size.
• There is no redirection between appliances in a cluster, meaning that I/O is sent to one of the two nodes that contains storage for the volume.
