Maintaining storage systems in clusters

Use the Edit Cluster menu to perform cluster maintenance tasks.

Adding a storage system to a cluster

Add a storage system to an existing cluster to expand the storage for that cluster. If the cluster
contains a single storage system, adding a second storage system triggers a change for the volumes
in the cluster to go from Network RAID 0 to Network RAID 10, which offers better data protection
and volume availability. The window which opens describes the data protection offered by this
change, and allows you to override the change for selected volumes, if necessary.
NOTE: Adding a storage system to a cluster causes a restripe of the data in that cluster. A restripe
may take several hours or longer.
Adding a new storage system is not the same as replacing a repaired storage system with a new
one. If you have repaired a storage system and want to replace it in the cluster, see

1. First add the storage system to the management group that contains the cluster.

5. Click OK.
6. Click OK again in the Edit Clusters window.
A confirmation message opens, describing the restripe that happens when a storage system

7. Click OK to confirm adding the storage system to the cluster.

Upgrading the storage systems in a cluster using cluster swap

Use cluster swap to upgrade all the systems in a cluster at one time. Using cluster swap allows
upgrading the cluster with only one restripe of the data.
1. Add the storage systems to swap to the management group that contains the cluster.
2. Select the cluster in the navigation window.
3. Click Cluster Tasks, and select Edit Cluster Swap Storage Systems.
4. To review the list of available storage systems along with the storage systems that are in cluster,
click View Storage System Details.,
5. In the Swap Cluster Storage Systems window, for each storage system being replaced in the
left column, select an available storage system from the list in the right column, as shown in
Figure 54 (page
