Fluid Cache Node Is Unavailable in
Enterprise Manager
Possible Cause The node failed during restart. The node was unable to perform a graceful shutdown
because the chkconfig command was used to shut down the Fluid Cache agent
service.
Solution Do not use the chkconfig command to disable the Fluid Cache agent service.
Perform normal node recovery procedures to return the node to normal operation.
Cached LUNs Are Unavailable
Possible Cause After restarting Fluid Cache or restarting a server, cached LUNs may not be immediately
available.
Solution Wait for the cached LUNs to reappear. It may take a significant amount of time to write
a large amount of data. The cached volumes reappear after the cache completes
recovery.
Possible Cause A fault in the cluster is preventing the volume from being recognized by Enterprise
Manager.
Solution Check the Enterprise Manager status page and event log for error messages.
Cannot Create a Fluid Cache Cluster
Possible Cause A minimum of three PowerEdge servers have not been configured for use with Fluid
Cache. Until at least three servers have Fluid Cache installed and configured, the option
to create a Fluid Cache cluster is unavailable.
Solution Add three or more nodes and configure the nodes before attempting to create a Fluid
Cache cluster in Enterprise Manager.
Possible Cause Network connectivity issues are preventing the creation of a Fluid Cache cluster.
Solution Check that the security settings are correct and the required ports and network
connections are open. See Checking Network Connections and
Checking Security Settings.
