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
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.
The system processes for some time, and then the server appears inside Fluid Cache Clusters in the
Storage tab.
The Add Devices to Cluster dialog box is displayed. By default, all devices compatible with Fluid Cache
are selected.
6 Clear the option next to unwanted cache devices or click the Unselect All option, and then select the
cache devices to be added. (Select the Select All option to use all available cache devices again.)
CAUTION: Any existing data on a cache device is lost when the device is added to the Fluid Cache
cluster. Back up this data before proceeding.
7 Click OK.
The device now appears in the list in the Devices section.
If you have a shared data application such as a cluster file system or clustered application, you may want to
add the server to a server cluster (a “subcluster”) inside the Fluid Cache cluster. See Mapping Volumes. To
create a subcluster, refer to the
Enterprise Manager Administrator’s Guide.
