A pseudo-client is a logical CommCell entity that represents one or more GPFS clusters. A user-defined instance, which contains a default subclient, is automatically created when you create a pseudo-client. This instance protects all the data on your GPFS cluster.
Warning: To ensure that a path that you specify as subclient content is accessible from all nodes of a GPFS cluster, do not add nodes that belong to two different GPFS clusters to the same instance.
