Removing Volume Mappings from a Subcluster

1. Make sure the volume is no longer in use and unmounted in vCenter.

2. In Enterprise Manager’s Storage view, expand Storage Centers if necessary and select the

appropriate Storage Center. (Do not select

Fluid Cache Clusters or its contents.)

3. In the Storage tab, expand Servers, and then the Fluid Cache clusters if necessary and select the

subcluster whose mappings you want to remove.

4. In the right pane, below the list of servers, select the volume and click Remove Mappings.

There may be some delay while the mapping is removed and dirty data in the cache is flushed to

main storage. When the mapping removal is complete, the volume’s icon in the Storage tab turns

from blue to gray color. You may need to manually refresh the display.

NOTE: The Fluid Cache mappings for the subcluster are listed in the Volumes area at the

bottom of the page.

NOTE: All Fluid Cache volume mappings must be removed before an ESXi host can be removed

from a Fluid Cache cluster.

Deleting a Volume From a Fluid Cache Cluster

Use Enterprise Manager to completely delete a volume from a Fluid Cache cluster while maintaining just

the cluster.

1. Click the Storage view.

2. In the Storage pane, expand Fluid Cache Clusters if necessary and select the cluster with the mapped

volume to delete.

3. In the Cache tab, expand Volumes, select the volume to be deleted and click Delete. The Delete

dialog box appears.

4. (Optional) Select Do you want to delete the Storage Center volume associated with the selected

Fluid Cache volumes?

to also delete the volume on the Storage Center.

CAUTION: If you select this option, it will delete the logical volume from the Storage Center

and all the data contained in that volume will be permanently lost.

5. Click OK.

Adding Servers to a Fluid Cache Cluster

NOTE: You should not add 2.1.0 hosts to a Fluid Cache cluster that contains 2.0.10 hosts because

the results will be indeterminate. This operation is not supported.

To add servers to a Fluid Cache cluster:

1. Log in to Enterprise Manager as a user with Administrator or Volume Manager privileges.

2. In the Storage view, expand Fluid Cache Clusters if necessary.

3. Right-click the Fluid Cache cluster (not Fluid Cache Clusters itself) and click Tasks → Add Servers to

Cluster.

The Add Servers to Cluster dialog box is displayed. By default, all servers are selected that have Fluid

Cache installed.

4. Clear the check boxes next to unwanted servers or select the Unselect All option, and then select

the servers to be added. (To use all available servers again, select the

Select All option.)

5. Click OK.
