Welcome to the Community,
all you need to do is to present the storage LUNs to both hosts using the same LUN-ID, so that both of them have access to the same datastores.
I'm assuming that by presenting the storage LUNs you mean adding a datastore. Won't that process format the VMFS LUN and erase all the existing data?

No, I'm talking about presenting the LUN from the storage system.

Once you present a LUN to an ESXi host, which already contains a VMFS datastore (i.e. is formatted with VMware's VMFS file system), the host will detect the datastore, and there's no need to format it again.
hello and welcome!
first question: do you have vCenter Server?
If not--> how can you create a VMWare cluster? No need to have shared storage between hosts as you may not leverage features such as vMotion and HA ( and all the dependant features)
insert the two hosts in the cluster.
present external storage wwn or iscsi iqn to the two hosts the hosts (remember to zone / mask on the fabric)
create a VMFS volume.
also the other host will get the same partition(s)
If the external storage is NFS, repeat Mount NFS Mount point for each host; there's no need to format it as it's NFS
PS: there is no master status: VMWare cluster is not a "Failback" cluster by design. VMFS is a clustered FS that's designed for small big file and supports the "VMWare Way " of doing Clustering.
with HA you can achieve the three 9s availability. Now with FT on 5.5 you can achive 9s availability on critical VMs (max 4 per host)
remember to give points and set the question as answered..
