Shutting Down and Restarting a Cluster
Shut down a cluster if, for example, you need to perform system maintenance but do not need to make any
configuration changes to the cache network itself.
To shut down a cluster:
1 Exit any applications that access cached volumes.
2 In Enterprise Manager, click Storage.
3 In the Storage pane, expand Fluid Cache Clusters if necessary, and then select the Fluid Cache cluster.
4 Click Shutdown.
The Shutdown window is displayed.
5 Click Yes.
The system processes for some time while data is flushed. There may be a significant delay for large
amounts of data.
NOTE: While a cluster is shut down, all cached volumes and their data are inaccessible. If you need
to maintain access to these volumes while the cluster is shut down, remap the volumes before
shutting down the cluster.
To restart a cluster:
1 Make sure the SAN and Storage Center are fully operational, and the cache network is configured and
running.
2 In Enterprise Manager, click the Storage view.
3 In the Storage pane, expand Fluid Cache Clusters if necessary and select the Fluid Cache cluster.
4 Click Restart.
Uninstalling the Fluid Cache Software
Uninstall the Fluid Cache software if a server will no longer be used for Fluid Cache.
Before uninstalling the software, you must remove all volume mappings and remove the server from its Fluid
Cache cluster. See Removing Volume Mappings and Removing a Server from a Fluid Cache Cluster.
To uninstall the Fluid Cache software, run the command:
rpm -e $(rpm —qa | grep FLDC)
Although this command removes all configuration information, in some cases you may want to remove all
components of Fluid Cache from your installation by also deleting the installation directory: /opt/dell/
fluidcache/
