The nodes cannot access the Dell PowerVault storage sys- tem, or the cluster software is not functioning with the stor- age system.

The PowerVault storage system is not cabled prop- erly to the nodes or the cabling between the PowerVault components is incorrect.

The length of the interface cables exceeds the maxi- mum allowable length.

Make sure that the cables are connected properly from the node to the PowerVault storage system. See the cabling instruc- tions in “Cabling the Cluster Hardware” in Chapter 4 of this guide.

Ensure that copper cables do not exceed 30 meters (m).

One of the cables is faulty.

Replace the faulty cable.

One of the nodes takes a long time to join the cluster.

The node-to-node network has failed due to a cabling or hardware failure.

Long delays in node-to-node communications may be normal.

Check the network cabling. Ensure that the node-to-node interconnection and the public local area network (LAN) are con- nected to the correct network interface controllers (NICs).

Verify that the nodes can communicate with each other by running the ping com- mand from each node to the other node. Try both the host name and Internet Pro- tocol (IP) address when using the ping command.
