If you have to use the same server names then your options are limited. The least disruptive way to do this then would be to evict BNODE01 from the cluster, remove the server from the server from the B NODE 01 storage group, and shut down that server. Now if the HBAs from BNODE01 will work in the new server then this gets a lot eaiser, as you can just install them in the new server, name it BNODE01, install the OS, drivers, and Navi agents/cli and all your zoning is done.  If everything is new then you will have to build the server from scratch, name it BNODE01, do all the routine work of zoning to the array and registering with the array. Once the registration is complete you follow the standard process for adding a node to the cluster using the add cluster node wizard. Before you start this you will need to add BNODE01 to the B NODE 01 storage group, and do a quick rescan in diskpart to ensure it sees all the disks. Once the disks are visible (but not mounted or assigned a drive letter) then you can run the add node wizard.  Once BNODE01 is successfully in the cluster, then you can repeat the process for ANODE01 and then do the same on the second cluster.
we have 2 windows cluster A with two nodes and Cluster B with two nodes.  we are planing to refresh the hardware. these four nodes(old) are registered in the CX4- clariion and having storage allocated to it.  Now during the Cut over, ie activating the new zones for the new server and removing the old zone.(cisco switch)  What all step do I need to follow so that during the reboot  new servers sees the old storage.
