Do I have to make all storage (about 3-5 TB / lpar) visible to all nodes or just to the nodes that are intended to takeover the resources.
You'll have to make storage visible for prod nodes and backup nodes of course so they can takeover in case.
So zoning and masking should assure following:

S1 can see disks of A1, A4, A5
S2 can see disks of A2, A3, A5.

But I don't know if a node can be in more than 1 cluster which would be the case for S1 and S2. I guess Shockneck will tell Smilie

NAME
cmrunnode - run a node in a high availability cluster SYNOPSIS
cmrunnode [-v] [node_name...] [-t | -w none] DESCRIPTION
cmrunnode causes a node to start its cluster daemon to join the existing cluster. This command verifies the network configuration before causing the node to start its cluster daemon. To start a cluster on one of its nodes, a user must either be superuser(UID=0), or have an access policy of FULL_ADMIN allowed in the clus- ter configuration file. See access policy in cmquerycl(1m). Starting a node will not cause any active packages to be moved to the new node. However, if a package is DOWN, has its switching enabled, and is able to run on the new node, that package will automatically run there. If node_name is not specified, the cluster daemon will be started on the local node and will join the existing cluster. Options cmrunnode supports the following options: -v Verbose output will be displayed. -t Test only. Provide an assessment of the package placement without affecting the current state of the nodes or packages. The -w option is not required with the -t option as -t does not validate network connectivity, but assumes that all the nodes can meet any external dependencies such as EMS resources, package subnets, and storage. node_name... Start the cluster daemon on the specified node(s). -w none By default network probing is performed to check that the network connectivity is the same as when the cluster was configured. Any anomalies are reported before the cluster daemons are started. The -w none option disables this probing. The option should only be used if this network configuration is known to be correct from a recent check. RETURN VALUE
cmrunnode returns the following value: 0 Successful completion. 1 Command failed. EXAMPLES
Run the cluster daemon on the current node: cmrunnode Run the cluster daemons on node1 and node2: cmrunnode node1 node2 AUTHOR
