Cache Device Does Not Appear in List of Cache Devices

Possible Cause The cache device you are trying to add is not supported by Fluid Cache.

Solution Refer to the list of supported devices in Requirements for Fluid Cache.

Possible Cause The cache device is not functioning properly.

Solution To check device function, select the device in Enterprise Manager and in the Event

tab, look for a device failure message. Replace the cache device if necessary, using

instructions in the Dell Compellent Enterprise Manager User’s Guide.

Cache Device Cannot Be Added to a Cluster

Possible Cause The cache device is not functioning properly. Under some conditions, the process

of adding a device completes normally even though the device being added is not

functioning properly.

Solution

To check device function, select the device in Enterprise Manager and in the Event

tab, look for a device failure message.

If necessary, replace the cache device by following the instructions provided in the

Dell Compellent Enterprise Manager User’s Guide.

Cannot Select a Specific Cache Mode

Possible Cause There is an existing cache mode configured for the volume mapping. The cache

mode chosen for a volume mapping cannot be changed. The existing mapping

must be deleted, and a new mapping created. A new cache mode can be selected

while creating the new mapping.

Solution Remove the volume mapping and create a new mapping. When you create the

new mapping, you can then select a different cache mode (“cache policy”). See

Removing Volume Mappings and Mapping Volumes.
