PERC RAID adapters hang during boot.

The controllers for the shared storage system have the same SCSI ID as their peer adapters in the other system (that is, the same SCSI ID as the controllers connected to the other side of the shared

storage system).

Change one of the controller SCSI IDs so that the ID numbers do not conflict. Set the controller in the primary node to SCSI ID 7 (default), and set the controller in the secondary node to SCSI ID 6. See the PERC RAID adapter documentation for more information about setting SCSI host adapter IDs.

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

One or more nodes may have the Internet Connection Firewall enabled, and the RPC communication between the nodes has been inadvertently blocked.

Check the network cabling. Ensure that the node-to-node interconnection and the public network are connected to the correct network adapters.

Verify that the nodes can communicate with each other by running the ping command from each node to the other node. Try both the host name and IP address when using the ping command.

Configure the Internet Connection Firewall to allow communications that are required by the cluster service and the clustered applications or services. For more information see KB883398 at support.microsoft.com.
