Information Displays Differently 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 differently.

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 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 Client displays a "reconnect" message in the Fluid Cache display for a Fluid Cache

cluster it means that EM 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.

If the EM client displays a red mark over the cluster in the Storage Centers view of the cluster, it means

that the Storage Center is reporting that it cannot communicate with the cluster servers over the

management network.

• Verify that the network is operational between the cluster servers and the Storage Center by using a

network tool such as ping.

• Note that it may take several minutes for the Storage Center to report the cluster status (down or up).

Verify the Data Path is Working

The Storage Centers server view is present if the Storage Center is able to see data connections to the

cluster. The HBAs will be have a red mark if there are problems.

The Fluid Cache Clusters server view will show the HBAs from the Fluid Cache Servers perspective.

Depending on the server and its operating system, conditions such as connectivity may not be visible

from this view.

When checking for data connectivity, always check the Storage Centers view first.
