Not enough storage

What to do when storage is full

You can add a DS14 disk shelf to a cluster that is made up of DS14 disk shelves without powering down your cluster. This enables you to add disk shelves without a service interruption. However, you cannot add more disk shelves to your cluster than your cluster can support. See the NOW Web page at http://now.netapp.com for the amount of storage your cluster can support.

Considerations for adding storage to a cluster

The following list specifies the requirements and restrictions you need to be aware of when adding storage to an existing cluster:

Mirrored cluster--if you add a disk shelf to one plex, you should add the same storage capacity disk shelf to the other plex.
Standard cluster--If you add a DS14 disk shelf to a cluster that has FC9 disk shelves, the DS14 disk shelf must be the last disk shelf in the loop.
Note
See the System Configuration guide on the NOW Web page at http://now.netapp.com for additional restrictions.

Adding storage to a standard cluster

To add storage to an existing cluster, complete the following steps.
