NOTE: The Fluid Cache mappings for the server are listed in the Volumes area at the bottom of

the page.

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.

Removing a Server from a Fluid Cache Cluster

1. Make sure that no cached LUNs are in use by the ESXi server. Unmount VMFS datastores if present,

remove any RDMs or VMDKs, and so on.

2. If the server belongs to a server cluster (a “subcluster”) within a Fluid Cache cluster, remove the

server from the subcluster:

a. Prior to removing the server from a Fluid Cache cluster, you must shutdown the host or stop the

Fluid Cache service.

b. In Enterprise Manager’s Storage view, select the appropriate Storage Center. (Do not select Fluid

Cache Clusters or its contents.)

c. In the Storage tab, expand Servers if necessary and locate the server.

d. Right-click the server and select Remove Server from Cluster.

e. When asked to confirm the action, click OK.

In the Storage tab, the server now appears outside of the subcluster, but is still inside the Fluid

Cache cluster.

NOTE: Removing the server from the subcluster removes all mappings created for the

subcluster.

3. Power off the VSA:

a. Log in to the Windows vCenter client and in the Hosts and Clusters view, navigate to the VSA’s

ESXi host.

b. Right-click the VSA and select Power → Power Off. There is a delay while the system writes

cached data to disk. For a large quantity of data, this could take a considerable amount of time.

Periodically refresh the display until the VSA’s status shows that powering off is complete.

c. If you want to delete the VSA entirely, right-click the VSA again, select Delete from Disk, and

when prompted to confirm the action, click OK.
