Fluid Cache License File is Invalid
Verify that the license didn’t expire or that a system change caused the license to be invalidated.
• The Fluid Cache license status can be veried on either the Fluid Cache clusters’ Events tab or Cache tab.
• An evaluation license is valid for only 90 days. Contact your Dell sales representative to purchase a Dell Fluid Cache for SAN
license.
Option to Create Cluster Not Available
All of the prerequisites for creating a Fluid Cache Cluster must be satised before the option to do so appears.
• Must be running Storage Manager 6.5.1 or later.
• Must have a Storage Center attached that can support Fluid Cache.
• Must have a minimum of one Fluid Cache server congured for use with Fluid Cache.
• Must be running Dell Fluid Cache for SAN 2.0 later.
Unable to Add a Volume to a Fluid Cache Cluster
To verify the issue, check to see that both of the following items are true.
• Make sure all the Fluid Cache servers are on the same network as the Storage Center that is serving the volume.
• Make sure that the volume is not in use on another server or cluster.
Event Messages Are Not Being Delivered
The Storage Manager Data Collector is responsible for receiving alert messages and transmitting them to congured users. When
setting up Storage Manager on a multi-homed system, make sure to set messaging to use a NIC that is on the same network as the
Fluid Cache server(s), or congure routing on the cache server to be able to get to the address on the NIC the Storage Manager
Data Collector was congured to use.
Storage Center is Not Available
If you receive an error that you don’t have a Storage Center or you don’t see any Storage Centers, make sure that the Storage
Center
(s) is running version 6.5.1 or later.
Fluid Cache Server is Not Available
If you do not see a Fluid Cache server that you expect to be listed, click the Rescan button as the server may not have been
discovered by the other servers in the cluster.
Information Displays Dierently Between Storage Centers and Fluid Cache Clusters
The Fluid Cache Clusters display shows information from the Fluid Cache server perspective while the Storage Centers display
shows information from the
Storage Center perspective. If there is a communication issue between the Fluid Cache servers and the
Storage Center, they may each show that condition dierently.
There is some latency in gathering information from the Fluid Cache servers by both Data Collector and the Storage Center as well
as from the Dell Storage Manager Client gathering information from Data Collector. It could take several minutes for all parts of the
system to synchronize and show a consistent view.
Verify That All Parts of the Fluid Cache Cluster are Communicating with Each Other
If the Dell Storage Manager Client displays a "reconnect" message in the Fluid Cache display for a Fluid Cache cluster it means that
Storage Manager is no longer able to communicate with the Fluid Cache cluster through the management network.
• Verify that the network is operational between the Data Collector server and the Fluid Cache servers using a network tool such
as ping.
• If ping works but a reconnect to that address continues to fail, make sure that the Fluid Cache software is operational on the
server.
