Failover Cluster with two hosts - Format disks with disk managment from both hosts, or one host?

I'm creating a failover cluster that will use a cluster shared volume via iSCSI.  Went through the process of creating the iSCSI targets on both host nodes.  From host number one I used Disk Management to bring the disks (to be used for CSV and Quorum) online, initialize the disks and format with NTFS.  Before moving forward, do I need to do that same process from the other host?  There is contradicting info online.  Looking for some clarification.

Example of statement to not do anything to the disks from host two:

On the first Hyper-V Server, open the iSCSI initiator and connect the Server to both LUNs. Open the Server Manager and navigate to the Disk Management section. Bring both disks online (when needed), create two partitions and format them. Assign drive letters F:\ and G:\ to the partitions.  On the second Hyper-V Server, open the iSCSI initiator and connect the Server to both LUNs. Do not access the LUNs using the Server Manager, just connect the Server to the LUNs and that’s it.

Example of statement to do the same process to the disks from host two:

After this all those iSCSI disks will show up in each node's Disk Management console (diskMgmg.msc).  While in there, we need to right click on each disk and bring them Online. Then initialize all the disks and assign them Drive letters. This has to be done on all nodes that are going to be joined to the cluster.

You don't need to format from both nodes, you can, but it would be redundant.

However, surprisingly enough, the second option is more accurate. It doesn't instruct you to format the disk on both nodes, it does however instruct you to bring the disk online and assign them drive letters, which if you don't do, the cluster does it for you. And sometimes cluster might chose different drive letters on different nodes. So its better to assign them manually.
