Cannot Assign or Remove a Storage Center
Possible Cause The Storage Center is already assigned to another Fluid Cache cluster.
Solution In Enterprise Manager, see whether or not a Storage Center is listed for the Fluid
Cache cluster.
Possible Cause Network connectivity issues are preventing Enterprise Manager from
communicating with Storage Center.
Solution Make sure the network is functioning properly. Refer to Checking Network
Connections, Checking Security Settings, and Checking Storage Center
Connectivity.
Cannot Determine Which Cache Device Failed
Possible Cause One of the cache devices has failed on a server with multiple cache devices
installed, and it is not clear which of them failed.
Solution In Enterprise Manager, in the Cache tab, the failed cache device is identified by a
red X through it. Note the last digits of the number for this cache device. This
number matches the serial number printed on the label of the failed cache device.
Events for Fluid Cache Are Not Shown in Enterprise
Manager
Possible Cause When Enterprise Manager was installed, the Data Collector was not configured for
the correct IP address.
Solution Make sure the IP address that the Data Collector uses is accessible by the Fluid
Cache nodes. To view the IP address, start the Data Collector Manager, select
General Information, and note the IP address within the URL in the Web Site field.
Change the address if necessary and restart the Data Collector.
Cluster or Application Has Performance Issues
Possible Cause One or more cache devices are uninstalled, have failed, or do not have the correct
firmware or drivers.
Solution Use Enterprise Manager to check the functionality of the cache devices. See also
Checking the Cache Device Firmware and Driver.
Possible Cause The Compellent storage array is overloaded.
Solution In Enterprise Manager, check the storage latencies and throughput on the cached
volumes. Add more capacity to the Compellent array if necessary.
Possible Cause The application is not making use of the cache.
