Unable to form a 16-node cluster when all nodes are booted up at the same time (6320429)

Attempting to boot up all nodes of a 16 node cluster at the same time results in node panics and nodes hanging waiting for quorum.

This bug was caused due to incorrect configuration of the private interconnect switches. It is required to disable spanning tree for the switch ports used for the Sun Cluster private interconnects. This was not done for the switches on the 16 node cluster and hence this bug. The cluster cannot be brought online due to this bug.

In order to resolve this issue it is required to disable the spanning tree for the switch ports used for the Sun Cluster private interconnects.

Solution None.
